Inflammatory myofibroblastic tumor of the urinary bladder: A rare diagnostic challenge.

Abstract

We present a case of a 44-year-old male with gross hematuria and lower urinary tract symptoms (LUTS). Ultrasonography revealed a 3 cm lesion, initially non-indicative of bladder cancer. Magnetic resonance imaging (MRI) identified a 26 mm posterior bladder wall mass, suggesting muscle invasive bladder cancer (MIBC). Transurethral resection of the bladder tumor (TURBT) was performed. Histopathology and immunohistochemistry confirmed an inflammatory myofibroblastic tumor (IMT). No neuro- or angioinvasion was present. Follow-up clinical evaluation revealed no evidence of recurrence, and the patient remained asymptomatic with complete resolution of urinary symptoms.
