A unique presentation and rare pathological finding for urachal sinus

Ultrasound Evaluation of Dermal Sinuses/Fistulas in Pediatric Patients

A dermal sinus/fistula is a common condition; the relevant department should be consulted for appropriate treatment. It is important for radiologists to have adequate knowledge of these conditions to provide the correct diagnosis and recommend subsequent management. This review describes the following lesions: preauricular sinus, midline sinus of the upper lip, nasal dermoid sinus cyst, cheek fistula, first branchial cleft anomaly/sublingual branchial cleft anomaly, thyroglossal duct cyst/fistula, lateral cervical sinus/fistula, congenital dermal sinus/fistula of the anterior chest region, congenital skin sinus/fistula with a sternal cleft, and congenital prepubic sinus. On the basis of the skin orifice location and ultrasound images, radiologists can provide useful information to physicians.

Suprapubic versus prepubic sinus: a literature review

Urachal sinus usually presents with umbilical discharge and the opening can rarely be located between the umbilicus and the symphysis pubis and the so called suprapubic sinus (SPS). There is another different entity of cases reported in literature with a similar presentation but with an opening anywhere between the umbilicus and symphysis pubis but differs from SPS in the pathway of the tract and the epithelial lining. We report a case of a 2-year-old boy presenting with a prepubic sinus that was managed with surgical excision. After a thorough literature review, we compare our case to other prepubic and SPS.
