Bilateral perirenal urinoma with mediastinal extension

Abstract

We report a unique case of adult-type polycystic kidney disease (PKD) having bilateral chronic perirenal fluid collection with unusual extension. Fluid collections at both sides are connected across the midline anterior to the abdominal aorta and inferior vena cava. In addition, supradiaphragmatic extension through aortic hiatus was well demonstrated by computed tomography (CT). Antomical boundaries and relations between two perirenal spaces are evaluated.

Traumatic urothorax in a dog: a case report

“…The presence of urine within the thoracic cavity, termed urothorax or urinothorax, has been so far reported almost exclusively in human beings. It can result from urine accumulation and extravasation from the abdominal cavity or retroperitoneal space (Hase and others 1999, Sheleyfer and others 2006, Tortora and others 2006) because of blunt or penetrating abdominal or pelvic trauma (Waldron 2003, Adams and Syme 2005) with its leakage to the pleural cavity through an anatomical defect in the diaphragm (Kinasewitz 1997, Hase and others 1999, Störk and others 2002, Parvathy and others 2003), via diaphragmatic lymphatics (Corrier and others 1968, Kinasewitz 1997, Tortora and others 2006), or by passive leakage into the mediastinum followed by its rupture into the pleural space (Friedland and others 1971, Akpek and others 1995). The present communication reports, for the first time, a case of traumatic urothorax in a dog.…”
