Abstract
Background: Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm of little known etiology, originating from visceral tissue and soft tissues, which can occur in any area of the body. In the genito-urinary system, it mainly affects the bladder, and may present with hematuria, frequency, dysuria and, more rarely, fever and weight loss. Differential diagnosis by histopathology is essential to determine whether the treatment will be radical or conservative, with partial cystectomy or transurethral resection (TURP) being the first choice for these cases. Case Report: This was a 50-year-old female patient treated at the Urology Service of the Hospital Universitário São Francisco na Providência de Deus – HUSF with complaints of hematuria for one month, suprapubic pain and urge incontinence. A computed tomography scan of the patient's abdomen and pelvis showed a urinary bladder with normal contours and morphology, however, with heterogeneous content due to the presence of an amorphous, endophytic formation, which occupied about one sixth of the organ's volume and with attenuation of hematic tissue.
Based on the findings, it was recommended that the patient undergo a transurethral bladder resection for biopsy. After that, it was then indicated an open resection of the lesion due to its extensive size. The procedure was uneventful, and a complete resection of the lesion, which had a polypoid appearance, was possible.
Conclusion: The case presented is a classic example of urinary bladder IMT.
