case_images: Standing lateral dynamic X-rays showed a grade 1 listhesis at the L4-L5 level [Figure 1a and b]. Postoperative X-rays documented the TLIF at L4-L5 [Figure 1c and d].
case_images: Preoperative MRI revealed an intradural extramedullary mass lesion at the level of L5-S1 on right postero-lateral aspect. The lesion was hyperintense in T1WI (a and d), and hypointense on T2WI (b and e) with hyperintense to the cord on STIR sequence (c and f)

case_images: When the dura was opened longitudinally, it revealed a dark blood clot within a semi-transparent neomembrane [Figure 3].
case_images: Radiological follow up with T2WI showed no residual pathology and decompression of spinal cord
