Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm with unknown malignant potential that has been described in most organ systems. We present the case of a 3-year-old boy who was referred with lower urinary tract symptoms and macroscopic hematuria. An IMT was suspected after clinical, radiological, and surgical work-up, and the diagnosis was confirmed after a partial cystectomy was performed. A bladder-preserving approach is the treatment of choice, but close clinical follow-up is recommended because of the unknown biological behavior of these tumors.
