Follow-up pelvic MRI incidentally revealed that a 35-year old female patient had an urachal cyst on the bladder dome. A hysterectomy for cervical cancer had previously been performed. The urachal cyst was 1.1cm in diameter and transurethral en bloc resection was successfully performed. Histopathologically, the cyst was surrounded by a smooth muscle layer with the wall consisting of columnar and glandular epithelial cells. Transurethral en bloc resection is a useful procedure to excise and confirm the pathogenesis for a limited case of a small urachal cyst that extrudes into the urinary bladder.
