Abstract: | A 14-year-old girl was admitted to our hospital because of umbilical erythema and discharge. She had had an appendectomy at the age of twelve. Abdominal ultrasonography and cystoscopy revealed a large tumor-like mass at the posterior wall of the bladder. Computed tomography and magnetic resonance imaging revealed urachal sinus. The diagnosis of urachal abscess had been confirmed and conservative treatment had been continued by drainage via umbilicus and the administration of antibiotics. Total excision of the urachus was performed about one month later because the bladder mass was not reduced. Pathological findings revealed an inflammatory thickened wall of the urachus and no evidence of malignancy. We report this rare case of urachal abscess with a large mass in the retrovesical space. |
