Parathyroid cysts of the neck and mediastinum. Case report   总被引:1,自引:0,他引:1  
Five cases of parathyroid cyst are presented and the literature concerning this rare entity is reviewed. Three of the five cysts were located in the neck and were non-functioning. The other two were in the anterior mediastinum and functioning, and indeed were associated with hypercalcemic crisis. Four cases were treated surgically, and in one non-functioning parathyroid cyst both diagnosis and treatment were accomplished with fine-needle aspiration. The cystic appearance, color of the fluid contents, high content of parathyroid hormone and histologic features distinguish parathyroid cyst from the much commoner thyroid cyst. Non-functioning parathyroid cysts can be treated with fine-needle aspiration, whereas functioning cysts require surgical removal.  相似文献

BACKGROUND: We present our experience with thoracoscopic resection of mediastinal bronchogenic cysts in adults. METHODS: From November 1990 to September 1993, 20 patients with mediastinal bronchogenic cysts were operated on by thoracoscopy. The average cyst size was 4.9 cm, and the largest diameter was 10 cm. Ten cysts were located in the middle mediastinum and 10 in the posterior mediastinum. Two cysts were complicated. RESULTS: Thirteen bronchogenic cysts were resected completely by thoracoscopy. We had to convert thoracoscopy into thoracotomy because of bleeding in two cases and because of major adhesions to vital structures in five cases. There were no operative deaths and no postoperative complications. Mean hospital stay was significantly less in the completely thoracoscopically treated group. Long-term follow-up (range, 4.5 to 7.5 years) showed no late complications and no recurrence. CONCLUSIONS: Preoperative complications, intraoperative injuries, and major adhesions to vital structures seem to be the only unfavorable conditions to thoracoscopic treatment of bronchogenic cysts. This study found encouraging results for thoracoscopic excision of mediastinal bronchogenic cysts in selected patients.  相似文献

Fourteen new cases of parathyroid cyst are presented. Two distinct groups were identified: functioning and nonfunctioning. Patients with functioning cysts presented with hypercalcemia, tended to be men and were older. Patients with nonfunctioning cysts were all women, had normocalcemia and all presented with neck masses. Ultrasonography proved useful while radionuclide thyroid scans were often misleading. In the functioning group removal of parathyroid cysts resulted in postoperative normocalcemia in all cases. In the nonfunctioning cysts thyroid lobectomy was performed in five of six instances. Parathyroid cysts usually contain clear or serous fluid and are surrounded by a well-delineated plane of dissection. We believe that preoperative aspiration of cystic neck masses and consideration of the diagnosis of parathyroid cysts may avoid needless thyroid lobectomy.  相似文献

Parathyroid cysts are a rare situation, unusually in the mediastinum. The preoperative diagnosis could be more difficult in some atypical topographies and imaging characteristics in particular in case of huge mediastinal cyst. In the following years traditionally, in case of intrathoracic parathyroid cysts, sternotomy or thoracotomy have been the preferred approaches. We report a case of an older patient with a huge mediastinal parathyroid cyst removed successfully using videothoracoscopy.  相似文献

Hydatid disease remains a serious health problem for the Mediterranean countries, such as Turkey. Living in a rural area is an important risk factor for the disease. Hydatid cysts are usually located in the liver, lung, and brain. Mediastinal hydatid disease is very rare that have been only anecdotally in the literature. The objective of this study was to evaluate the clinical and radiographic findings and surgical treatment of this unusual lesion. Between 1985 and 2002, 11 cases with primary mediastinal hydatid cyst were treated surgically at our clinic. Median age was 28.4 and ranged from 19 to 46 years. Symptoms included chest pain in nine patients (82%), and cough in six patients (54%). The cyst was located in the anterior mediastinum in four patients (36%), in the posterior mediastinum in five patients (45%) and in the middle mediastinum in two patients (18%). All cysts were intact except one cyst that ruptured into right intrapleural space. Surgical approach was right thoracotomy in five patients (45%), left thoracotomy in three patients (27%), and median sternotomy in three patients (27%). Total pericystectomy was chosen as the surgical procedure in all patients except four (36%), who had cystectomy and local curettage for cyst located vital structures. There were no complications and mortality postoperatively. Primary hydatid cysts of the mediastinum are distinct clinical entity that must be considered when caring for a patient with a mediastinal mass in endemic regions. Because of surrounding vital structures the cyst should be treated without delay.  相似文献

Background:Most abnormal parathyroid glands can be removed through a standard cervical incision; even those in the superior mediastinum. Those located in certain areas of the mediastinum, for example posteriorly or in the aortopulmonic window, historically have required excision through a median sternotomy or thoracotomy. Angioablation is a nonsurgical alternative to management of these lesions.Study Design:We present two case reports of mediastinal parathyroid adenomas that were excised thoracoscopically, and review the literature regarding the management of mediastinal parathyroid adenomas.Results:Both patients who underwent precise localization and thoracoscopic excision of their mediastinal parathyroid adenomas had resolution of their hypercalcemia with minimal associated morbidity and shortened recovery periods.Conclusions:We suggest that thoracoscopic excision of mediastinal parathyroid adenomas is the better means of controlling hypercalcemia secondary to parathyroid adenoma in those patients considered for either median sternotomy, thoracotomy or angiographic ablation where the exact location of the lesion can be established preoperatively.  相似文献

A 29-year-old man had been diagnosed with an anterior mediastinal cyst 6 years earlier and was undergoing follow-up. At a follow-up visit, a newly developed cystic lesion was found in the middle mediastinum; therefore, the anterior mediastinal cyst and the middle mediastinal cyst were resected by thoracoscopic surgery. It was observed that the middle mediastinal cyst originated from the thoracic duct, and the thoracic duct was clipped. Pathologically, the diagnosis was a thymic cyst of the anterior mediastinum and a thoracic duct cyst of the middle mediastinum. The patient developed chylothorax after surgery, and a second thoracoscopic operation was performed. It revealed that part of the clipping of the caudal thoracic duct was incomplete, and leakage of chyle was observed. Hence, the clipping was performed again. The course after the second surgery was good. Thoracic duct cysts are rare even among mediastinal cysts and thus require caution due to their tendency to expand.  相似文献

Bronchogenic cysts are closed sacs considered to be the result of an abnormal budding of the respiratory system. They are lined by ciliated epithelium and have focal areas of hyaline cartilage, smooth muscle, and bronchial glands within their walls. They are seldom seen in the adult, and most are thought to be asymptomatic and free of complications. During a 20-year period, 86 patients underwent resection of a bronchogenic cyst of the mediastinum (66 patients) and lung (20 patients). There were 47 women and 39 men whose ages ranged from 16 to 69 years. Seventy-two percent of patients (67% with mediastinal cysts and 90% with cysts of the lung) were symptomatic at the time of operation, and the majority had two or more symptoms. Despite extensive investigations, which in some cases included computed tomographic scanning (n = 12) and angiography (n = 22), a positive diagnosis was never made preoperatively even if it was suspected in 57% of patients. In nearly all patients, the operative approach was that of a posterolateral thoracotomy. All but two mediastinal bronchogenic cysts could be locally excised, but all bronchogenic cysts of the lung required pulmonary resection (lobectomy, 13; limited resection, 6; pneumonectomy, 1). Major operative difficulties were encountered in 35 patients, all of whom were symptomatic preoperatively. Thirty-three patients had a complicated cyst; the complications consisted of fistulization (n = 16), ulcerations of the cyst wall (n = 13), hemorrhage (n = 2), infection without fistulization (n = 1), and secondary bronchial atresia (n = 1). Overall, 82% of patients had a bronchogenic cyst that was either symptomatic or complicated or both.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

OBJECTIVE: Primary cysts constitute 25% of all masses in the mediastinum. Because radiological investigations are often inconclusive, many adults require mediastinoscopy, thoracotomy, video-assisted thoracic surgery, or computed tomography-guided transbronchial, transesophageal, or transcutaneous aspiration to confirm the cystic nature of these lesions. Minimally invasive procedures fail when the cyst contents are gelatinous and mucoid (failure to aspirate) or when the cyst wall continues to secrete fluid. Though Pursel reported mediastinoscopic extirpation of benign cysts 35 years ago, it remains a "therapeutic curiosity" with sporadic reports of its usage. We report 2 successful mediastinal cyst extirpations performed as outpatient procedures and review the literature with regards to its management. METHODS: A rigid, 8-mm mediastinoscope was inserted into the anterior mediastinum following the creation of a 2-cm suprasternal incision and dissection along the anterior surface of the trachea. After aspiration, cytology of the contents revealed their benign nature. Right paratracheal cysts in 2 adult males were successfully removed mediastinoscopically by blunt and sharp dissection. RESULTS: Histopathology revealed benign mesothelial cysts in both instances. Both patients had an uncomplicated procedure and were discharged within 23 hours. No other pathology was detected on mediastinoscopy, and follow-up at 3 months and 6 months has revealed no recurrence. CONCLUSION: Mediastinoscopic cyst removal is a minimally invasive procedure with a very low morbidity and mortality rate. Morbidity, recovery, and discharge times are much less than those of more invasive procedures (video-assisted thoracic surgery / thoracotomy). We suggest that it should be the first-choice procedure for the excision of appropriately located benign mediastinal cysts.  相似文献

Parathyroid cysts are rare and even more rarely cause a neck mass resembling a goitre. Such large parathyroid cysts may involve the mediastinum, growing to a sufficient size to produce symptoms related to obstruction, and if functioning, primary hyperparathyroidism. Parathyroid cysts should be considered in the list of differential diagnoses of anterior neck masses to allow for appropriate preoperative investigation to avoid unnecessary confusion at the time of operation. We report a case where a functioning parathyroid cyst presented as a retrosternal goitre to emphasize the potential pitfalls associated with their diagnosis and management.  相似文献

Between 1965 and 1982, we treated 46 patients with cystic lesions of the thymus. Thirty patients had anterior mediastinal cysts, nine had cysts which were large enough to be both cervical and mediastinal, and seven had cervical cysts. The majority (40/46) presented with asymptomatic masses. Six patients presented with distinct complaints: dysphagia (four patients), hoarseness owing to vocal cord paralysis (one patient), and cervical pain (one patient). All six had benign thymic cysts. The diagnosis of a cystic mass was established prior to operation by ultrasonography and computed axial tomography in our last three patients. These two techniques delineated the capsule and the central fluid in those three cases. All 46 patients had the mass resected without mortality or significant morbidity, except for resection of the phrenic nerve in one patient with malignant cystic thymoma. Cervical cysts were excised through cervical incisions. Cysts located in the anterior mediastinum and cervical-mediastinal cysts required median sternotomy or right thoracotomy for successful resection. Pathological examination showed that 39 patients had benign thymic cysts, three had benign cystic thymoma, two had malignant thymoma, one had a seminoma arising in the thymus, and one had a lymphoblastoma. We believe that a cystic thymic mass which can be detected by ultrasonography and computed tomography, although usually benign, does not eliminate the possibility of malignancy, and resection, therefore, is indicated.  相似文献

INTRODUCTION: Hydatid disease, a clinical entity endemic in many sheep- and cattle-raising areas, is still an important health problem in the world. Extrapulmonary location of cysts in the thorax is rare. We report our experience with intrathoracic but extrapulmonary hydatid cysts and discuss concepts of treatment. METHOD: In our Thoracic and Cardiovascular Surgery Department at the Dicle University School of Medicine, 133 patients with thoracic hydatid cysts were managed surgically between January 1990 and October 2002. In 14 (10.5%), the cysts were extrapulmonary but within the thorax, located in the pleural cavity, mediastinum, pericardium and diaphragm, or in pleural fissures. Cysts were intact in 12 patients and ruptured in 2. Radiographs of the chest were the main means of diagnosis; all patients with mediastinal and diaphragmatic cysts and some with pleural cysts were also scanned with computed tomography. All patients were managed surgically. RESULTS: We operated on 3 mediastinal, 2 diapragmatic and 1 pericardial hydatid cyst, as well as 6 in pleural fissures and 2 in the pleural space. Lateral thoracotomy was chosen as the surgical incision in all patients except 1 (7% of the 14), who had median sternotomy for a pericardial hydatid cyst. Empyema developed in 2 patients (morbidity, 14%). No patient died perioperatively. CONCLUSIONS: Hydatid cysts may be found in many different sites. Surgery to obtain a complete cure is the treatment of choice for most patients with intrathoracic but extrapulmonary cysts; excision must be done without delay to avoid or relieve compression of surrounding vital structures.  相似文献

Variation in management based on type of choledochal cyst   总被引:6,自引:0,他引:6  
The management of 23 patients treated for choledochal cysts at the Oregon Health Sciences University between 1969 and 1990 is reviewed. The median age was 27 years, with a range from 1 month to 90 years. Seventy-eight percent of patients presented with abdominal pain, and 35% were jaundiced. Three patients presented with cholangitis, two with cyst rupture, and one with recurrent pancreatitis. Nine patients had had previous biliary surgery. The diagnosis was made in all patients with ultrasound and/or cholangiography. Fifteen patients (65%) had type I cysts, 2 had a type II cyst, 5 (22%) had type III cysts, and 1 had a type IV cyst. Stones were present in four (17%) cysts, and all excised cysts were benign. Seventeen patients with type I and II choledochal cysts had complete cyst excision and choledochoenterostomy. Four of five patients with type III cysts had endoscopic cyst incision and drainage, while the fifth patient had transduodenal cyst excision and sphincteroplasty. The patient with a type IV cyst had extrahepatic cyst excision and choledochojejunostomy. There were no operative deaths. Two postoperative complications occurred: cholangitis and a prolonged ileus. All patients had resolution of their pain and jaundice. Two patients had late cholangitis. Cyst excision and choledochojejunostomy are the treatment of choice for types I and II choledochal cysts. Extrahepatic cyst excision and choledochojejunostomy may be adequate treatment for type IV cysts. Endoscopic incision and drainage is appropriate for selected patients with type III cysts.  相似文献

Mediastinal exploration to resect ectopic parathyroid is required in approximately 2% of all cases of hyperparathyroidism. Traditionally, it has been performed through a midsternotomy or thoracotomy. A few reports about thoracoscopic resection of mediastinal parathyroid were published recently. We report here successful video-assisted thoracoscopic resection (VATS) of a mediastinal parathyroid and present a review of all previously reported cases. A 42-year-old woman presented with spontaneous fracture of the left femur and hypercalcemia. She had previously undergone cervical parathyroidectomy for primary hyperparathyroidism. A computed tomography (CT) scan of the chest and a technetium scan showed ectopic mediastinal parathyroid. The patient underwent successful thoracoscopic resection of ectopic parathyroid. A total of 26 patients were reviewed, 21 in the English literature and 5 in others. Of the 21 patients reported in the English literature, 16 had primary hyperparathyroidism (1 degrees HPT), whereas 5 had secondary hyperparathyroidism (2 degrees HPT). All but 3 patients had undergone previous cervical exploration. Ectopic mediastinal parathyroid was localized preoperatively in all by CT scans of the chest and nuclear scans. All 21 patients had successful thoracoscopic resection. All but 3 had parathyroid adenoma. Postoperatively, serum calcium (Ca ), phosphate (PO4 ), and parathormone (PTH) values returned to normal in all patients. Age and sex of the patient, type of hyperparathyroidism (1 degrees or 2 degrees ), size of the gland, its location within the anterior mediastinum, the approach used to resect it (right or left thoracoscopic), and final histopathology of the resected gland (adenoma or hyperplasia) had no bearing on the success of thoracoscopic resection. The data seem to suggest that thoracoscopic resection of mediastinal parathyroid is a less-invasive, effective, and safe procedure. Accurate preoperative anatomic localization by CT and nuclear scans of the chest is the key to success.  相似文献

Mediastinal cysts are rare anomalies. The purposes of this study were to present our experience with mediastinal cysts, which were thoracoscopically treated in our clinic, and to discuss our findings along with those from the literature. We retrospectively investigated 13 patients who were diagnosed and thoracoscopically treated for mediastinal cysts in our clinic between January 2008 and December 2011. Seven patients were female and six were male. The average age of the patients was 41.3?±?20.3 (7–82 years old). The mediastinal cysts comprised five pericardial cysts: four bronchogenic cysts, one hydatid cyst, one benign cystic teratoma, one thymic cyst, and one neurenteric cyst. In the case of a ruptured hydatid cyst, we passed it to thoracotomy intra-operatively due to the presence of advanced adhesion related to inflammation. Postoperative complications and mortality did not occur in any case. The average postoperative hospitalisation period was 3.8 days (2–7 days). Video-assisted thoracoscopic surgery in mediastinal cysts is a reliable and effective approach with low morbidity and a shorter hospital stay.  相似文献

Parathyroid cysts are relatively uncommon. They may be non-functioning or associated with primary hyperparathyroidism. Three patients are presented, including one with a large mediastinal parathyroid cyst, and these cases illustrate the range of pathological and clinical features.  相似文献

Analysis of the management of 7 cases of extradural arachnoid cyst is presented. A brief review of the literature on the subject is presented. Seven cases of extradural arachnoid cysts were treated surgically between the years 1996 to 2002. These patients were analysed retrospectively. The average follow-up period was 32 months. Three patients were males and four were females and their ages ranged from 12 to 35 years. The patients presented with predominant complaint of progressive motor deficits. There were two cysts in the dorsal region, four in the dorsolumbar region and one in the cervicodorsal region. The extradural arachnoid cyst was located posterior to the dural tube and in the midline in six cases and all these cysts had bilateral multiple intervertebral foraminal extensions. In the case with a cervicodorsal cyst, the cyst was anterolateral to the dural tube and there was no foraminal extension. The surgery comprised of wide exposure of the cyst and radical marsupialization or resection of the cyst wall. There was no recurrence of the cyst during the period of follow-up. Radical resection of the walls leads to a lasting cure from extradural arachnoid cyst. The site of communication of the cyst contents with subarachnoid CSF could not be identified during the surgery in the series.  相似文献

A case of hypercalcemic crisis secondary to a large functioning parathyroid cyst is presented. Because none of the theories about the origin of parathyroid cysts are well substantiated or accepted, these cysts should be referred to simply as parathyroid cysts, functional or nonfunctional.  相似文献

Atypically located pericardial cysts   总被引:1,自引:0,他引:1  
Pericardial cysts are uncommon benign abnormalities and are most often found in either cardiophrenic angle. We present the cases of 3 patients with a cyst in the mediastinum and review the literature. Pathological examination confirmed the diagnosis of pericardial cyst. Clinicians should include pericardial cyst in the differential diagnosis of mediastinal masses.  相似文献
