چکیده
but distinctive lesion with uncertain malignant potential and unknown etiology. IMT has been reported in various anatomic sites, but is rare in genitourinary tract. Pathologically, the lesion is composed of dominant spindle cell proliferation with variable amounts of an inflammatory component. These spindle cells are now known to be myofibroblasts, which account for the current designation for this disease (1-4). IMT presents a diagnostic dilemma for radiologists and pathologists because the radiologic and histological features often mimic those of a malignant neoplasm. However, the clinical course is known to be benign as the tumor grows slowly and does not metastasize or undergo a malignant transformation (2). Case Reports
