Figure 1: Sagittal MRI showing a bulky conus and a heterogeneous ill-defined lesion extending from the D12-L5 levels, which appears predominantly isointense on T1WI (A) and iso-hyperintense on T2WI (B). The visualized cord cranially also edematous changes in the form of hyperintense signals on T2 images (B). The dermal sinus tract can be seen clearly at the L5 level (white arrow in B). Post-contrast images (C) showing heterogeneous rim enhancement with internal cystic areas. These findings were suggestive of a DST with intradural abscess. Intra-operative photograph (D) after laminectomy showing the DST (arrow) ending in dura (asterisk)
