Imaging spectrum of spinal dysraphism on magnetic resonance: A pictorial review

Figure 19 Infected dermal sinus with intraspinal dermoid. T1 weighted sagittal image (A) showing a dermal sinus (white arrow) with an intraspinal lesion (black arrow) showing mildly hyperintense signal with expansion of spinal cord. On T2 weighted sagittal (B) and STIR coronal (C) images the intraspinal lesion appears hyperintense with well defined hypointense rim. On post contrast image (D) there is peripheral enhancement of the intraspinal lesion and the tract.
