Inflammatory Pseudotumor of the Urinary Bladder: A Case Report


Abstract
Inflammatory pseudotumor of urinary bladder is a rare benign entity that clinically and radiologically simulates a malignant tumor. This benign lesion can easily be mistaken for sarcoma, and only careful pathologic examination can provide a
definite
diagnosis. It is important to recognize this lesion as benign to avoid the potentially serious consequences of misdiagnosis. A 53-year-old man presented with a history of micturition pain and urinary frequency despite of symptomatic treatment
with
antibiotics for 2 weeks. Cystoscopic examination, ultrasonography and CT revealed a well defined mass with central necrosis. The mass was located at the left lateral wall of the bladder, and it was 3¡¿3 cm sized round shape. We suspected benign
tumor by
above diagnostic modalities and we confirmed infalmmatory pseudotumor by frosen section of mass, followed by partial cystectomy was performed. Awarenes of this unusual lesion is important to prevent unnecessary surgical procedure. We report a
cases
of
inflammatory pseudotumor of the urinary bladder and reviewed 21 cases of this disease including our case.
