We report a 32-year-old female case of a right adrenal gland mass detected on CT scan at medical checkup. CT and MRI showed a mass of 5.1 cm made of fat and calcification in the right adrenal gland, leading to the clinical diagnosis of adrenal myelolipoma. Because of its relatively large size and the patient's desire, the patient underwent gasless single-port retroperitoneoscopic adrenalectomy ...

SUMMARY Castleman's disease is a rare condition. In its classic form Castlema's is a solitary lesion, two third of patients have tumour like mass in the mediastinum. Extrathoracic sites also could be affected including those where lymph nodes normaly occur ancl rarely tissues where lymph nodes are not found. More recently there have been several reports of patients with multi centeric involvem...

Schwannomas are tumors originating from Schwann cells in the nerve sheath. Although they can appear on many parts of the body, they occur most frequently in the head and neck. Furthermore, they are very rarely seen in the retroperitoneal region. Ancient schwannoma is a sub-type of schwannomas that is quite rare. In this study, the case of a retroperitoneal ancient schwannoma, which showed cysti...

A 58-yr-old woman was referred to our hospital for hematuria and a painless, rapidly growing abdominal mass. Computed tomography showed a rounded mass, 23x19cm in diameter, spread over the left retroperitoneal space. A thrombus was observed occupying the left renal vein until the vena cava. Total left nephrectomy with excision of the retroperitoneal mass was carried out. A cavotomy highlighted ...

INTRODUCTION Retroperitoneal leiomyomata are rare. They are either mistaken preoperatively for malignant retroperitoneal tumors or dealt with as cases of subserous leiomyomata that turn out intraoperatively to be huge retroperitoneal masses of unknown nature. CASE PRESENTATION We report the case of a 46-year-old nulligravid female patient of Middle Eastern ethnicity who presented to our unive...

Prevalence of pulmonary sequestration accounts for up to 6.4% of all congenital pulmonary malformations. We report on a 40-year-old woman who underwent excision of an aberrant solid retroperitoneal mass in the left subdiaphragmatic area. The mass was identified to be an extralobar pulmonary sequestration. The diagnosis could be made without surgery by percutaneous tissue biopsy and imaging. We ...

INTRODUCTION Primary retroperitoneal mucinous cystadenoma is a rare tumor prevailing specifically in female gender. Its histogenesis is still unclear and its diagnosis is mainly based on morphological characteristics. CASE PRESENTATION the subject is a 44 years old man presenting an abdominal pain on the right side, with a palpable mass which appeared four months ago. Abdominal ultrasound (ec...

The differential diagnosis of retroperitoneal mass includes liposarcoma, leiomyosarcoma, malignant fibrous histiocytoma, neurofibroma, stromal tumor, teratoma, and lymphoma. Leiomyosarcoma is rare with poorer prognosis than other soft tissue sarcomas. Soft tissue sarcoma of retroperitoneal origin often remains asymptomatic until tumor enlargement, leading to diagnosis at advanced stages.

Introduction: Retroperitoneum is the third most common extragonadal site for occurrence of teratoma in children, after sacrococcygeal region and gonadal sites. Although many authors have previously reported laparoscopic removal of benign retroperitoneal teratoma in adults, the experience in pediatric setting is extremely limited. Material and methods: We report our experience with laparoscopic ...

Angioleiomyoma (vascular myoma) is a rare type of leiomyoma originating from smooth muscle cells and containing thick-walled vessels. There are only a few cases of retroperitoneal angioleiomyoma reported in the literature. Herein, we present the ultrasonography, magnetic resonance imaging and histopathological findings of an asymptomatic patient with a pelvic retroperitoneal angioleiomyoma whic...
