[Leiomyoma of the bladder: report of two cases].
We report 2 cases of leiomyoma of the urinary bladder. A 41-year-old female visited our hospital with the complaint of pollakisuria. A solid tumor of the urinary bladder was found by ultrasonography. A large shadow defect at the left-anterior wall was shown by drip infusion pyelography (DIP). Computed tomographic scan (CT) and magnetic resonance imaging (MRI) also revealed a large tumor. T1-weighted image revealed a homogeneous low intensity tumor and T2-weighted image disclosed heterogeneous low intensity tumor. Cystoscopy revealed a large submucosal tumor. Partial cystectomy was performed, and she has had neither recurrence nor metastasis for 36 months. A 32-year-old male was referred to our hospital with the complaint of macrohematuria. A solid tumor of the urinary bladder was found by ultrasonography. A shadow defect was not clearly detected by DIP. A large tumor was detected on the anterior wall by MRI. T1-weighted image showed a homogeneous low intensity tumor and T2-weighted image disclosed a high intensity tumor. Cystoscopy revealed a submucosal tumor on the anterior wall. Urine cytology did not suggest a malignancy. The biopsied specimens revealed only an inflammatory change in the mucosa. Partial cystectomy was carried out. He has had neither recurrence nor metastasis for 29 months. Histological diagnosis in both cases was leiomyoma of the urinary bladder.
