Abstract

Inflammatory pseudotumor is a rare benign condition of unknown cause. A 19-year-old female presented with gross hematuria and storage symptoms to the emergency. Contrast-enhanced computed tomography scan revealed a mass of 5 cm × 6 cm involving the dome and anterior wall of the bladder. Urachal carcinoma was kept as a possibility and transurethral biopsy of the aforementioned lesion was performed. The histopathology revealed inflammatory myofibroblastic tumor (IMT) of the bladder. A laparoscopic partial cystectomy was undertaken with adequate resection margins and the histopathology of the lesion confirmed IMT. When evaluating a mass in the genitourinary tract in a young individual, IMT should be considered as a possibility.
