Imaging findings of atypical leiomyoma of urinary bladder simulating ureterocele

Abstract

Abstract Bladder leiomyomas are relatively rare benign tumors of the bladder. They represent <0.5% of all urinary bladder tumor. In the literature, only about 250 cases reported worldwide. They are commonly found in middle-aged females. Patients present with variety of clinical presentations with predominance of obstructive urinary symptoms. Ultrasound bladder is the first preferable diagnostic tool. Definitive diagnosis is made by histopathological examination. Surgical excision is almost highly effective, leaving a low recurrence rate. We report a 34-year-old male who presented with complaints of dysuria and incomplete voiding. Ultrasound showed a cystic fluid-filled bladder mass (ureterocele), which was excised through a transurethral resection. The histopathologic diagnosis was bladder leiomyoma.
