Eosinophilic cystitis (EC) is a rare inflammatory condition characterized by eosinophilic infiltration into the bladder wall. It often presents symptoms common to urological issues such as urinary tract infections, hematuria, bladder stones, or bladder neoplasms. Here, we describe a case of a 44-year-old male veteran with a history of multiple tuberculosis episodes who presented to the Emergency Department with dysuria, suprapubic pain, and gross hematuria.

Initial imaging and cystoscopy concerned bladder neoplasia; however, subsequent pathological evaluation showed EC. This case underscores the importance of considering EC in the differential diagnosis of bladder tumors, especially when imaging describes bladder wall thickening in a patient without risk factors for bladder malignancy.
