A 37‑year‑old female presented with difficulty in passing urine for 2 years. Magnetic resonance imaging (MRI) on various pulse sequences revealed a globular mass lesion suggestive of leiomyoma in the urinary bladder. Leiomyoma of bladder is a very rare entity. Only about 300–350 cases are reported worldwide. On 3T MRI leiomyoma of the bladder may give varying appearance as compared with previously reported cases on 1.5 T possibly due to higher magnetic field strength. Leiomyoma of bladder is a benign condition, and the prognosis is excellent. Partial cystectomy was done, and histopathology examination confirmed the bladder leiomyoma.
