Extrarenal angiomyolipomas (ERAMLs) are rare tumors that present as incidentalomas upon imaging for other conditions. Retroperitoneal ERAMLs present a unique challenge from a diagnostic and treatment standpoint as they can mimic other benign and malignant retroperitoneal tumors. We present a case of a 39-year-old female with a 19.3 cm × 13.5 cm × 10.7 cm left extrarenal retroperitoneal mass. Hi...

The author reported a 48-year-old female patient who presented right pelvic mass with urinary incontinence and lower abdominal discomfort. Based on the preoperative imaging, provisional diagnosis was mesenchymal sarcoma. In the intraoperative findings, huge mass abutting to ...

Primary retroperitoneal pseudocysts are rare entities. Though laparoscopic approach has been described in their treatment, open surgical excision is still the mainstay of treatment for these lesions. We present a case of giant retroperitoneal pseudocyst and its successful laparoscopic excision. The patient was a 27-year old female. Contrast enhanced CT scan of the abdomen and ultrasonography co...

  This is a rare case report of bilateral Schwannoma in lower poles of both kindeys in a 36 year old diabetic man.preoperative radiographic evaluations suggested the presence of two solid retroperitoneal tumors attached to the lower poles of both kindeys without any regional or distant extension.the final diagnosis was confirmed by histological and immonohistological studies.

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 ...

Retroperitoneal fibrosis is a rare condition. It is idiopathic or secondary to various diseases including autoimmune diseases and atherosclerosis [1]. Although its pathogenesis is unknown, it is now considered that immune responses may play an important role in this disease [1]. Retroperitoneal fibrosis is also seen in metastatic carcinomas from many organs as a desmoplastic reaction [1]. Howev...

necrotizing soft tissue infections (nstis) are polymicrobial infections with high morbidity and mortality. we report a case of retroperitoneal nsti in an immunocompetent young male, with clinical symptoms and signs mimicking acute pancreatitis (pseudo-cullen’s and pseudo-grey-turner’s signs). the initiating lesion was a pustule which progressed and mimicked acute pancreatitis. ct scan showed fe...

Spontaneous retroperitoneal hemorrhage is a lethal cause of acute abdomen that is most frequently related to drugs, coagulopathy and intra-abdominal tumors. In patients with polymyositis and dermatomyositis, acute abdomen is attributed to intestinal vasculitis causing ischemia, ulceration or perforation. Spontaneous retroperitoneal hemorrhage, however, has rarely been reported in patients with ...
