Infection along the congenital dermal sinus tract is well known. However, congenital dorsal dermal sinus presenting with intramedullary abscess is quite rare. The sinus tract usually presents in the midline and acts as a portal of entry for infection that may manifest as meningitis, extradural or subdural abscess and may further involve the cord. Surgical drainage of pus and complete excision of the sinus tract is the standard treatment. Here we describe an infant with an infected congenital dorsal dermal sinus with atypical presentation as large paracentral abscess in the upper back. We further highlight the importance of recognising and treating these skin dimples even when clinically silent to avoid catastrophic complications.
