case_images: Examination of the back revealed a very small, abnormal tuft of hair in the midline in the mid lumbar region suggesting the presence of occult spinal dysraphism [Figure 1]. T4 to T6, separated by a bony spur. The two hemicords then entered the same dural sheath but before uniting into a single, normal spinal cord, divided into another Type 1 SCM from T9 to T11, separated by another bony spur. The two hemicords then fused into a single dural sheath before continuing as a single spinal cord from T12 onward [Figure 2]. The MRI also showed a DST at L1 [Figure 1] and an epidural abscess from T12 to L3 level [Figure 3].
case_images: This sequence (axial section) shows the spinal cord as seen at T6, T11, and T12, respectively
