Cystitis cystica is an uncommon chronic reactive inflammatory disease that is believed to be brought on by a tumor, calculi, infection, or obstruction of the urothelium.

[5] Although many affected individuals share a common feature of chronic irritation, infection, or inflammation, the exact cause of cystitis cystica remains unknown.

[6] Cystitis cystica cystoscopy features can range from a large bladder cyst or mass to an essentially unremarkable appearance.

Cystitis cystica can show up on a CT urogram as a number of small, rounded filling defects in the bladder wall that range in size from 2 to 5 mm.

Following diagnosis confirmation, the mainstays of treatment are the elimination of aggravating factors, symptomatic management, antibiotics and chemoprophylaxis, and, in the event that non-pharmacological measures prove ineffective, surgical intervention.
