Neoplasm of unspecified behavior of bone, soft tissue, and skin [D49.2], Reason for Study: ^Reason: s/p resection of L1-2 tumor History: postop Post left L1 hemilaminectomy with L1-L2 external fixations using screws and rod. In addition, the left posterior inferior aspect of the L1 vertebral body shows partial resection status with ovoid signal voids (series 601, image 37) likely indicating postoperative changes such as blood products, Gelfoam or metal fragments. Follow up imaging can be considered. There is no evidence of abnormal enhancement.In particular previously seen abnormal enhancing left L1-2 neuroforaminal lesion is not seen on today's scan.There is normal lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The conus medullaris terminates at the L1 level. The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation except minimal disc dessication of L5S1.
1. Complete resection of previously seen left L1-L2 neuroforaminal enhancing mass with postoperative changes.2. No evidence of residual lesion on this scan.3. Ovoid signal void lesion on the left posterior inferior aspect of the L1 vertebral body likely represent postoperative changes. Follow up imaging can be considered if clinically indicated.
