After viewing this exhibit, the viewer will understand the normal anatomy and histology of the urinary bladder wall (emphasizing the submucosa) and develop an imaging approach to disease processes which can mimic urothelial lesions arising within the bladder submucosa or from extrinsic sites that secondarily involve the bladder wall.

1. Review the relevant anatomy and histology of the bladder wall, emphasizing the submucosa. 2. Discuss methods to evaluate submucosal and extrinsic bladder lesions focusing mainly on CT and MRI techniques. 3. Review common and uncommon submcosal and extrinsic bladder pathologies including: a. Mesenchymal tumors: Submucosal leiomyoma, Neurofibroma, Hemangioma, Lipoma and Paraganglioma b. Reactive lesions: Cystitis Cystica and Cystitis Glandularis and Nephrogenic Adenoma c. Urachal anomalies d. Extrinsic lesions including: Endometriosis, Adjacent inflammatory processes (e.g. Crohn’s, Diverticulitis), Peritoneal carcinomatosis and in pregnant patients placental invasion
