A Rare Case of an Intramedullary Spinal Cord Abscess Due to Escherichia coli in a Pediatric Patient

Spinal cord abscess is a rare entity, particularly in the pediatric population. Spinal cord abscesses can be located in extradural, subdural and intradural (intramedullary or extramedullary) regions of the cord. Among these locations, intramedullary is extremely uncommon. There have been few case reports of intramedullary spinal cord abscess since its first description in 1830. We describe a 2 year-old boy with a history of neonatal meningitis due to E.coli who presented with refusal to walk and was subsequently found to have intramedullary spinal cord abscesses at multiple levels. Culture of the abscesses again revealed E.coli. The patient was noted to have a pit located just superiorly to his sacral spine. Imaging revealed the presence of a dorsal dermal sinus tract. It is important to evaluate anatomical abnormalities, especially in the setting of serious bacterial infections, such as meningitis, as they have the potential to serve as a reservoir for infection.
