Recent resection of an extradural dorsal fibrous mass at T11. Some small dorsal aspects are very adherent to the dura and were left. There are postoperative findings related to recent T11 extradural mass resection. There is are prominent areas of hypointensity in the posterior epidural space at the T10-11 level, which likely represent thickening of the ligamentum flavum, which result in mild spinal canal stenosis. Although no large mass is otherwise apparent, evaluation for tumor is limited due to the lack of contrast. There is persistent diffuse T2 hyperintensity and mild swelling of the lower spinal cord. The vertebral body heights are preserved. The thoracic spine alignment is anatomic. There are multiple foci of T1 and T2 hyperintensity in the vertebral white matter, which likely represent hemangiomas or focal fat.
