A unique presentation and rare pathological finding for urachal sinus.
We report an otherwise well developing 2-year-old girl who presented with a urachal sinus with its opening located at the midline between umbilicus and the pubic symphysis. Diagnosis was made by ultrasound preoperatively, and confirmed during surgery. Additionally, columnar epithelium was found in the portion of sinus tract traversing the abdominal wall. Metaplasia of the sinus tract is worrisome, as urachal carcinomas have been traditionally characterized to result from this process.
