Intramedullary spinal cord abscess—rare complication of a congenital dermal sinus: Report of a case in a toddler

Abstract

Abstract Lumbosacral region is the commonest location for a dermal sinus (DS). The DS provides a natural pathway for infections of the deeper tissues such as the meninges or spinal cord, depending on its termination. One of the rarest and serious complications of a DS is an intramedullary spinal cord abscess. One such case has been reported here. A 2-year boy presented with high-grade fever, acute onset flaccid paraplegia and urinary retention. A L5 level DS was noted. Imaging showed a D12-L5 heterogeneously enhancing intradural lesion suggestive of an abscess. Multi-level laminectomy and drainage of abscess with removal of an inclusion epidermoid was performed. Complete recovery of all neurological functions was achieved that remained stable at 60 months follow up.
