Abstract:
The authors present a case of a 42-year-old lady who visited her gynaecologist with dysuria and a sensation of incomplete voiding for 2 weeks. Urine culture grew Escherichia coli and blood studies were normal. Pelvic ultrasound revealed a smooth well-defined mass arising from the bladder wall. She was referred to the urologist who requested CT and MRI for further evaluation. These modalities confirmed an intramural bladder mass with normal overlying mucosa. The mass was deemed contributory to her symptoms and a decision was made to excise the mass surgically. Via a transurethral approach, cystoscopy revealed a smooth well-circumscribed intramural mass. This was partially excised. The mass was found to be a leiomyoma. Except for an uncomplicated urinary tract infection, her postoperative course has been uneventful.
