Abstract
Dermal sinus tracts are remnants of incomplete neural tube closure. Dermal sinus tracts in the spine range from asymptomatic pits to tracts with significant disease. Congenital spinal dermal sinus tract can produce significant morbidity if not adequately managed. Spinal subdural abscess caused by the spread of an infection within the dermal sinus tract is rare in children. We now described a 3-year-old male who presented with extensive spinal subdural abscess resulting from dermal sinus tract that was low-lying in the sacral area.

Dermal sinus tract complicated with spinal subdural abscess in a 3-year-old boy.
A. Sagittal T2WI shows high signal intense lesion in the subdural space occupying lesion from T7 to L3.
B. Gadolinium enhanced sagittal T1WI shows rim-like enhancement in the subdural lesion, and transverse line with low signal intensity (white arrow), suggesting dermal sinus.
C. Gadolinium enhanced axial T1WI shows the lesion more clearly as being subdural and intramedullary.
