Holocord abscess in association with congenital dermal sinus.

Intramedullary spinal cord abscess in children is rare and holocord abscess is rarer. An 18-month-old girl presented with rapidly progressive paraplegia with fever for 2 months. The patient had complete flaccid paraplegia with absent sensation below D4 level. There was very small dermal sinus discharging pus in the lower lumbar region. Magnetic resonance imaging showed evidence of extensive multiloculated intramedullary abscess extending from D4 to L5 with cord edema upto cervical level. Laminotomy, excision of the dermal sinus and myelotomy, and evacuation of intramedullary abscess was performed. Escherichia coli and Pseudomonas were grown on culture. The child was treated with long-term parenteral antibiotics and started showing neurological improvement. Holocord abscess secondary to congenital dermal sinus is extremely rare and this is only the fourth report of such an instance.
