Patient aged 27 years with no allergies or history of interest. She came from the gynaecology department where an ultrasound scan showed a neoformative image in the right retrotrigonal area. She had no associated urological symptoms.

Intravenous urography confirmed the ultrasound finding of a repletion defect in the right lateral area, as well as the C.A.T. study.

Cystoscopy showed a raised area with no mucosal alteration at that level.

Transurethral resection was performed, confirming the finding of bladder leiomyoma.

The postoperative evolution was satisfactory, as was the follow-up in outpatient clinics with annual endoscopic studies.
