We evaluated the effect of voluntary exercise on spontaneous physical activity (SPA) and food consumption in mice from 4 replicate lines bred for 57 generations for high voluntary wheel running (HR) and from 4 non-selected control (C) lines. Beginning at ~24 days of age, mice were housed in standard cages or in cages with attached wheels. Wheel activity and SPA were monitored in 1-min intervals...

Primary retroperitoneal mucinous cystadenomas are uncommon tumors whose incidence in the pediatric population is very low. We present the case report of a 17-year-old female with a primary retroperitoneal mucinous cystadenoma, borderline type, and describe the successful laparoscopic resection of the mass. 2014 The Authors.

Well-differentiated retroperitoneal liposarcomas are slow growing and low-grade tumors, reaching usually huge size before being symptomatic and so diagnosed, therefore with increase of the surgical risk and of the probability of dedifferentiation. Inguinal location of these tumors is unusual and rarely diagnosed.

Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrect...

Endoscopic retrograde cholangiopancreatography (ERCP) is a valuable diagnostic and therapeutic procedure in the management of pancreatic and extrahepatic biliary tract diseases. Although rare, it is related to several complications including retroperitoneal duodenal perforation. The perforation results in air accumulation in the retroperitoneal, pleural or subcutaneous space. We present a case ...

UNLABELLED A female patient with a history of recent abortion was transferred in critically ill condition in our hospital. CT imaging on emergency basis depicted an abscess in the right retroperitoneal space that included the head of fetus, along with rupture of the right lateral wall of uterus. Spiral CT enabled prompt diagnosis and therapy of this rare abortion-related complication. KEYWORD...

Purpose. To report the phenomenon of infected retroperitoneal sarcoma (RPS).Method. Two case reports.Results. Both patients died soon after laparotomy.Discussion. Infected RPS is identified as an entity not clearly documented in the literature. It should probably be added to the list of poor prognostic factors when planning the management of patients with RPS.

Introduction Retroperitoneal fibrosis (RF) is a fibrotic process in the retroperitoneum, that often causes ureteral obstruction. This condition, first described by Albarran in 1905, became an established clinical entity in 1948 owing to the work of Ormond. Studying the origins of this illness, Koep and Zuidema (1977) reviewed 481 cases of RF, of which 68% were considered idiopathic. This study ...

BACKGROUND Dedifferentiated liposarcomas represent heterogeneous tumors with lipomatous and nonlipomatous elements starkly juxtaposed. It is thought that the high grade nonlipomatous elements of the tumor portend a worse prognosis. CASE PRESENTATION A 19.8 kg heterogeneous retroperitoneal tumor was successfully and completely resected. Because of its extent, no additional treatment modalities...

Retroperitoneal fibrosis (RPF) is a rare inflammatory process associated with the development of extensive fibrosis around the abdominal aorta and surrounding retroperitoneal structures. The symptoms of RPF are often insidious and non-specific resulting in diagnostic delay with ensuing complications related to the progressive fibrotic deposition. A common complication of RPF is ureteric obstruc...
