Ultrasonographic diagnosis of uriniferous perirenal pseudocyst

Abstract

A child with a traumatic uriniferous perirenal pseudocyst was presented. The diagnosis was not made by routine radiological studies, but ultrasound examination demonstrated a perirenal fluid accumulation clearly. The usefulness of the ultrasound examination in the diagnosis of this condition was emphasized. The characteristic finding in ultrasonogram consists of a hydronephrotic kidney and its invagination into the echolucent mass. When perirenal cystic lesions are demonstrated by ultrasound, the junctional zone between the cyst and kidney should be carefully checked for signs of invagination of the kidney into the cyst.

Partial ablation of a para‐ureteral pseudocyst without ureteronephrectomy in a cat

“…Only a few case reports of retroperitoneal masses in cats have been described (Aronson 2002, Liptak and others 2004, Marvel and MacPhail 2013): fibrous masses following renal transplantation (Aronson 2002), sublumbar abscess associated with discospondilitis (Packer and others 2005), infarction (Ragni and Fews 2008) and urinoma (Lemire and Read 1998, Moores and others, 2002, Worth and Tomlin 2004, Pollaci and Nicoli 2011). …”

“…In particular, urinoma is a rare pathology in small animals; however, several case reports have already been described (Tidwell and others 1990, Lemire and Read, 1998, Bacon and others 2002, Moores and others 2002, Worth and Tomlin 2004).…”
