Bronchogenic cyst of the posterior neck mimicking lymphatic malformation

Bronchogenic cysts are embryologic malformations of the foregut and are rarely found head and neck region. Here we present a case of an upper scapular/lower posterior neck cystic mass which was initially suspicious for lymphatic malformation but confirmed by pathology to be an ectopic bronchogenic cyst.     

A rare case of pelvic bronchogenic cyst treated by laparoscopic surgery

A 31‐year‐old man with pain in his thigh was diagnosed with a benign presacral cystic mass. We performed laparoscopic subtotal resection of the cyst utilizing mobilization of a total mesorectal excision procedure used in low anterior resection for rectal cancer. Histopathological findings showed that the cystic lumen of the specimen was lined with pseudostratified columnar ciliated epithelium and had glandular structures and smooth muscle in its wall, leading to a diagnosis of bronchogenic cyst. The postoperative course was uneventful, and as of 6 months after surgery, the patient was doing well with no evidence of recurrence.     

A retroperitoneal bronchogenic cyst clinically mimicking an adrenal mass: three case reports and a literature review

Bronchogenic cysts are a congenital primitive foregut-derived developmental malformation, generally occurring in the posterior mediastinum. Their development in the retroperitoneum is extremely rare. Imaging techniques, such as multidetector computed tomography (MDCT), are typically effective in the detection of these lesions. Here, we describe three cases of a retroperitoneal cyst presenting as a para-adrenal mass. Only one boy presented with abdominal pain, and the other two showed no clinical symptoms. Endocrinological evaluation of all three cases was performed, and no adrenal hormone secretion was detected. All three cases were misdiagnosed preoperatively. Each patient underwent surgery, and one symptomatic patient became asymptomatic after surgery. Pathologic examination confirmed all three masses as bronchogenic cysts. The three cases showed some similar MDCT imaging features, including a complete adrenal structure, a cystic or solid mass in the adrenal region, and no obvious enhancement. Therefore, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal masses, even though accurate preoperative diagnosis remains difficult. A contrast-enhanced MDCT scan may be useful for differentiating hyper-attenuated cysts from other soft tissue masses.     

Gastric bronchogenic cyst diagnosed by endosonographically guided fine needle aspiration biopsy

We report a case of a gastric bronchogenic cyst diagnosed via endosonographically guided fine-needle aspiration (EUS-FNA) biopsy. A 60-year-old woman was referred to our hospital for an endoscopic ultrasound (EUS) examination because of a gastric subepithelial lesion detected by upper gastrointestinal endoscopy. EUS examination revealed a lesion that appeared to originate from the gastric submucosa but seemed to extend beyond the gastric wall. The latter finding raised concerns that the lesion might represent a cystic neoplasm rather than a simple cyst. Subsequently, EUS-FNA was performed to establish a definitive diagnosis and to guide further management. Cytologic evaluation of aspirated material revealed the presence of benign-appearing ciliated columnar epithelial cells within a mucinous background. Based on imaging and EUS-FNA findings, a diagnosis of gastric bronchogenic cyst was made and surgical resection was avoided.     

Esophageal bronchogenic cyst excised by endoscopic submucosal tunnel dissection: A case report

BACKGROUND Esophageal bronchogenic cyst(EBC) is a rare congenital disease that is difficult to diagnose preoperatively, and treatment remains controversial.CASE SUMMARY We report a 53-year-old Chinese woman hospitalized in our hospital following the discovery of a submucosal protruding mass of the esophagus by upper endoscopy. A preliminary diagnosis of EBC was made by endoscopic ultrasonography(EUS), and treatment was accomplished by endoscopic submucosal tunnel dissection(ESTD). The pathological results verified the diagnosis. No scar changes or cystic lesion within the original lesion were found under EUS after a 3-mo follow-up.CONCLUSION EUS is valuable for the preliminary diagnosis of EBC and surveillance. ESTD is a safe and effective treatment for EBC. Further evaluation of complications and long-term follow-ups are required.     

Video‐assisted segmental resection of an intrapulmonary bronchogenic cyst mimicking a middle mediastinal cystic tumor

We report a case of an intrapulmonary bronchogenic cyst that radiologically mimicked a cystic tumor of the middle mediastinum. During video‐assisted thoracoscopic surgery, the lesion was confirmed to be in the lung parenchyma rather than in the mediastinum. A video‐assisted thoracoscopic anterior basal segmentectomy was eventually performed, and an intrapulmonary bronchogenic cyst was the diagnosis based on histology.

COPD与原发性支气管肺癌临床分析

目的 探讨慢性阻塞性肺病(COPD)合并原发性支气管肺癌的可能发病机制、临床特征及早期诊断。方法 对26例COPD合并肺癌患者与单纯COPD患者进行对照分析 。结果 与单纯COPD组症状、体征比较 ,胸痛、痰血、咳嗽性质改变、声音嘶哑、胸腔积液、进行性消瘦有显著性差异 ;X线表现中央型肺癌17例(65%) ,周围型肺癌8例(30.7 %) ,弥漫型1例(4.3 %)。结论 吸烟、COPD本身可能是COPD合并肺癌的主要原因 ;COPD患者伴胸痛、痰血、咳嗽性质的改变、声音嘶哑、胸腔积液、进行性消瘦应警惕合并肺癌的可能 ;定期X线和痰脱落细胞筛查对COPD合并肺癌的早期发现有一定的临床意义 ;胸部CT和纤支镜检查对COPD合并肺癌的临床诊断价值较大。     

Exogastric cystic gastric leiomyoblastoma with unusual CT appearance

Gastric leiomyoblastomas are rare tumors between leiomyomas and leiomyosarcomas in terms of their malignant potential. This article describes 2 cases of exogastric cystic gastric leiomyoblastoma with unusual location and computed tomographic (CT) appearance. The CT findings of these cases were unlike those of usual smooth muscle tumors, but closely simulated cystadenomatous tumor of the ovary or pancreas.

Sonographic diagnosis of gastric duplication cyst communicating with the gastric lumen

Gastric duplication cysts are rare congenital anomalies, which account for about 7% of all enteric duplications. We report the sonographic findings of a rare case of gastric duplication cyst, communicating with the gastric lumen in a 30-year-old woman.     

Inflammatory myofibrohistiocytic proliferation presenting as giant gastric pseudotumor

A 5-year-old boy presented with refractory microcytic anemia, growth failure, and markedly elevated sedimentation rate. Computed tomographic (CT) and upper gastrointestinal study disclosed an ulcerated 9-cm large gastric mass, which proved to be an inflammatory myofibrohistiocytic proliferation (IMP). The characteristic clinical and radiologic features of this rare entity are herein reviewed.     

Abdominal bronchogenic cyst: A rare case report

BACKGROUNDBronchogenic cysts are cystic masses caused by congenital abnormal development of the respiratory system, and usually occur in the pulmonary parenchyma or mediastinum.CASE SUMMARYA rare case of a bronchogenic cyst discovered in the abdominal cavity of a 35-year-old man is reported. Physical examination found a space-occupying lesion in the patient’s abdomen for 4 d. Laparoscopic exploration found the cyst tightly adhered to the stomach and its peripheral blood vessels; therefore, intraoperative laparotomy was performed. The cystic mass was resected en bloc with an Endo-GIA stapler. The final postoperative pathological diagnosis confirmed an abdominal bronchogenic cyst.CONCLUSIONThis is a rare case of a bronchogenic cyst that was discovered within the abdominal cavity of a male patient. The cyst is easily confused with or misdiagnosed as other lesions. Therefore, it is necessary to distinguish abdominal bronchogenic cyst from gastrointestinal stromal tumor, Meckel’s diverticulum, enteric duplication cyst, or lymphangioma. Although computer tomography and magnetic resonance imaging were the primary diagnostic approaches, endoscopic ultrasound-guided fine-needle aspiration could assist with clarification of the cytological or histopathological diagnosis before surgery.     

Isolated gastric varices: Splenic vein obstruction or portal hypertension?

The presence of isolated gastric varices without esophageal varices is thought to be highly suggestive of splenic vein obstruction. A review of our radiologic files revealed 14 patients with isolated gastric varices on barium studies performed during the past 10 years. Eight of the 14 patients had adequate clinical and/or radiologic follow-up to suggest the pathophysiology of the varices. Seven had evidence of portal hypertension, and the remaining patient had evidence of splenic vein obstruction. Six patients had signs of upper gastrointestinal (GI) bleeding. Double-contrast upper GI examinations revealed thickened, tortuous fundal folds in 6 patients and a lobulated fundal mass in 2. Thus, most patients with isolated gastric varices have portal hypertension rather than splenic vein obstruction as the underlying cause.
