A primary retroperitoneal ganglioneuroma was found incidentally in a 44-year-old man. Computed tomography revealed a homogeneous mass just above the right kidney. T1-weighted magnetic resonance imaging demonstrated the homogeneous mass, but T2-weighted imaging revealed a heterogeneous mass with a markedly high intensity area. The tumor was resected through a transabdominal approach. The resected specimen measured 11 x 9 x 4.5 cm and weighted 270 g. Histological examination showed that the lesion was a ganglioneuroma composed of mature ganglion cells and nerve fibers. 相似文献

A 50-year-old woman was admitted under a diagnosis of abdominal tumor. Ultrasonography and CT scanning were performed, and a right retroperitoneal tumor was detected. Absolute curative resection was performed. The resected tumor was 13.5 x 11.5 x 9.0 cm, and histologically diagnosed as ganglioneuroma. To our knowledge, 99 cases have been reported in Japan. During a twelve-month follow-up period, the postoperative course was uneventful and no recurrence had been noted. 相似文献

The ganglioneuroma is a very rare tumor arising from sympathetic nerve system. An asymptomatic retroperitoneal ganglioneuroma was found incidentally in a 35-year-old woman. Ultrasonography, computed tomography, and magnetic resonance imaging showed a retroperitoneal mass extending to the left adrenal gland, and surrounding abdominal aorta, celiac axis, left renal and adrenal arteries, and veins. The tumor was resected and histologic examination showed ganglioneuroma. 相似文献

A 67-year-old woman was evaluated for asymptomatic microscopic hematuria. Intravenous urography and computed tomography demonstrated an adrenal mass, but the workup for a functional adrenal tumor was negative. The mass was surgically resected, with a histologic diagnosis of adrenal ganglioneuroma. No further treatment was necessary. After the diagnosis was made, the patient reported a family history positive for neuroblastic tumors. Two of her grandchildren had presented at early ages with a ganglioneuroblastoma and a third had presented with a ganglioneuroma. This presentation is unique because ganglioneuroma, especially that of adrenal origin, is rare in the adult population, and familial cases are extremely uncommon. 相似文献

A 35-year-old man presented with a 17-month history of abdominal distension and left upper quadrant pain. He had no episodes suggesting the presence of hypertension. Hormonal studies were insignificant. Imaging studies demonstrated a bulky tumor with cyst formation measuring 22 cm. Preoperative differential diagnoses included an adrenal tumor, extra-adrenal retroperitoneal tumor and pancreatic mucinous tumor. Intraoperatively, no abnormality was observed in the pancreas. A tight adhesion of the tumor to the left kidney necessitated an en bloc resection of the tumor with the left kidney. The resected specimen, 22 x 20 x 8 cm, weighed 5,050 g. Pathologically, the tumor was ganglioneuroma originating from the left adrenal gland. Convalescence was uneventful, and abdominal symptoms disappeared. The patient has been doing well without evidence of recurrece 48 months after the operation. 相似文献

A patient with an incidentally diagnosed adrenal ganglioneuroma is reported. A 37-year-old man who underwent abdominal computed tomography (CT) in the course of evaluating liver dysfunction was found to have a right adrenal tumor. Laboratory data including results of endocrinologic tests were normal except for a slight elevation of plasma aldosterone. With a preoperative diagnosis of non-functioning right adrenal tumor, resection was performed. The tumor specimen was noncystic weighing 150 g and measuring 10 x 8 x 3 cm. The histopathologic diagnosis was ganglioneuroma originating from the adrenal gland. Adrenal ganglioneuroma is relatively rare, 147 cases including ours have been reported in Japan. Increasing numbers of these tumors are being found incidentally by ultrasonography or CT. Ganglioneuroma is a benign tumor, and disagreement exists concerning diagnosis and indications for surgery. 相似文献

A 38-year-old man was referred to our clinic with the complaint of upper abdominal discomfort. Ultrasonography and computerized tomography showed a mass occupying the left retroperitoneal space. Endoclinological results were within the normal range except for 17-OHCS and 17-KS. Preoperative diagnosis was left non-functioning adrenal tumor. Exploration was done via transperitoneal approach. The specimen weighed 100 g and was 11 x 6 x 5 cm in size. Histopathological diagnosis was ganglioneuroma of the left adrenal gland. There have been 35 reported cases with ganglioneuroma of the adrenal gland including our case in the Japanese literature and we reviewed the pathogenesis and treatment of this rare disease. 相似文献

A case of malignant peripheral nerve sheath tumor of the bladder in a 57-year-old man with multiple neurofibromatosis type 1 is presented. The patient had a recent history of a transurethrally resected bladder ganglioneuroma. A probable histogenetic association between these two extremely rare neoplasms is proposed. 相似文献

Ganglioneuroma is relatively rare, and difficult to distinguish from other tumors due to lack of image findings specific for ganglioneuromas. In this report, two cases of ganglioneuroma preoperatively diagnosed as non-functioning adrenal tumor and retroperitoneal tumor are reported. A 25-year-old male and a 29-year-old male visited our institute with chief complaints of upper abdominal pain and asymptomatic microscopic hematuria, respectively. Computed tomographic scan and magnetic resonance imaging showed a 7 x 6 x 5 cm solid tumor above the upper pole of the right kidney in the former case, 8 cm poorly enhanced tumor grown surrounding the left renal artery in the latter case. Surgical resection was performed in both cases. In the latder case, since intraoperative histological examination showed no malignant finding, renal vessels penetrating in the tumor were preserved by transecting the tumor. Postoperative histological examination revealed an adrenal ganglioneuroma and a retroperitoneal ganglioneuroma in the former and latter cases, respectively. A ganglioneuroma can be surgically dissected with favorable prognosis, but preoperative differential diagnosis is sometimes difficult due to few specific radiological and laboratory findings. 相似文献

We herein present an exceedingly rare case of intrathoracic ganglioneuroma that was surgically resected in an elderly patient
over 70 years of age. A 74-year-old woman was asymptomatic, but a computed tomography (CT) scan of the thorax indicated the
presence of a posterior mediastinal mass paravertebrally. A thoracotomy was thus performed under a strongly suggested diagnosis
of a neurogenic tumor because of the appearance and position of the mass on the chest CT and magnetic resonance imaging findings,
and measuring 6.9 × 5.8 × 1.6 cm. Not only tumors originating from the nerve sheath, but also neurogenic tumors occurring
in young patients such as ganglioneuroma, should be included in the different diagnosis of posterior mediastinal tumor occurring
in elderly patients. 相似文献

A 67-year-old male presented for examination of a retroperitoneal tumor, incidentally found by abdominal computed tomography (CT). CT and magnetic resonance imaging (MRI) revealed a round heterogeneous tumor, 10 cm in diameter, at the left renal hilus and involving the left renal vein. The tumor was low-intensity on T1-weighted MRI imaging, and high-intensity on T2-weight MRI imaging. The tumor was easily resected via a transabdominal approach. The pathological diagnosis was ganglioneuroma. 相似文献

Ganglioneuromas are rare benign tumors of neural crest origin, arising from ganglia of the sympathetic nervous system and adrenal medulla. These masses are usually detected during the first 2 decades of life and are generally discovered incidentally. We present a 5-year-old boy with sickle beta-thalassemia whose hypertension is caused by a perihilar ganglioneuroma encasing the right renal artery and distorting the right renal vein. The tumor was resected and the child's blood pressure subsequently normalized. 相似文献

IntroductionGanglioneuromas are well-differentiated benign tumors that arise from sympathetic ganglion cells. In ganglioneuromas of the retroperitoneum, nonadrenal cases are resected by laparotomy due to the proximity to major vessels. There have been few reports of laparoscopic resection for retroperitoneal paraaortic ganglioneuromas. We experienced a case in which laparoscopic resection was required for a 90-mm ganglioneuroma adhered to the aorta and inferior mesenteric artery.Presentation of caseA 49-year-old female patient presented with epigastric pain. Computed tomography showed a 90 mm retroperitoneal tumor, partially located between the aorta and inferior mesenteric artery. A definitive diagnosis was not obtained, and laparoscopic excision of the retroperitoneal tumor was performed transabdominally. The patient recovered without postoperative complications and left the hospital on postoperative day 8. Postoperative pathological findings revealed a ganglioneuroma from the abdominal periaortic plexus.DiscussionWe searched the literature for nonadrenal ganglioneuromas resected laparoscopically using a transabdominal approach and summarized the tumor locations. The median age was 33 years, and the median tumor size was 50 mm. Regarding the surgical results, the median operative time was 170.5 min, median blood loss was 21.5 mL, and median postoperative stay was 7 days.ConclusionLaparoscopic resection of nonadrenal ganglioneuromas is feasible even when a tumor adheres to major blood vessels. 相似文献

Idiopathic aneurysm of the inferior vena cava is rare. Many aneurysms are asymptomatic; others are diagnosed after complications develop. Ganglioneuroma is an infrequently occurring benign tumor preferentially located in the mediastinum and retroperitoneum. Generally the clinical manifestations are symptoms of compression related to growth of the mass. We present a case report of idiopathic aneurysm of the inferior vena cava associated with retroperitoneal ganglioneuroma. The tumor was resected in combination with a procedure to correct the aneurysm that has not previously been described, ie, tangential resection and primary lateral venorrhaphy. The technique provided excellent short-term results. 相似文献

We report on a 23-year-old woman with a right adrenal tumor 13 cm in diameter who was treated by laparoscopy. The patient was asymptomatic, and the tumor was incidentally diagnosed on abdominal ultrasonography. A subsequent computed tomography (CT) of the abdomen confirmed a 12 x 7 x 8-cm homogenous mass of the right adrenal. Magnetic resonance imaging (MRI) showed a solid mass measuring 13 x 7 x 7.5 cm arising from the right adrenal. Laparoscopic complete excision of the mass was accomplished through a transabdominal lateral approach. The postoperative period was uneventful, and the patient was discharged on the second postoperative day. Histology was consistent with an adrenal ganglioneuroma. Two years later, there is no evidence of recurrence on abdominal CT scan. 相似文献

A 14-year-old girl was referred to our hospital for examination of a right adrenal tumor, incidentally found by abdominal ultrasound sonography. Computed tomographic scan and magnetic resonance imaging showed a 44 x 20 mm solid tumor in the right adrenal region. Endocrinological examination were within normal limits except for slightly increased serum aldosterone. Laparoscopic adrenalectomy was performed and the tumor was histologically diagnosed as ganglioneuroma originated from the right adrenal medulla. 相似文献
