Features consistent with a large, acquired or secondary urinary bladder diverticulum. Acquired diverticula at this age are generally secondary to a cause of bladder outlet obstruction and include prostatomegaly, neurogenic bladder, and urethral stricture. In this instance, prostatomegaly and chronic bladder outlet obstruction was the likely cause.

Sonographically, the poor identification of bladder communication, unfortunately, directs to a differential diagnosis for simple intrabdominal cystic masses including mesenteric cysts, pancreatic pseudocysts, and hydatidosis.
