Cystitis Cystica Presenting as Multi-loculated Large Bladder Cysts in a Patient with Lower Urinary Tract Symptoms

Abstract

Cystitis cystica is a common benign histopathological finding on cystoscopic biopsy and has a typical macroscopic appearance of multiple small cystic-looking lesions in the bladder on cystoscopy. It may be incidental or related to urinary tract infection or inflammation. We describe a rare case of a patient presenting with lower urinary tract symptoms (LUTS) who underwent transurethral resection of large multi-loculated bladder cysts which were suspicious for bladder malignancy on imaging; but histology turned out to be cystitis cystica.
