 There is continued evolution of postsurgical changes from T6 to T9 including left T7, T8 and T9 hemilaminectomies and left T8 pedicle resection for resection of aneurysmal bone cyst. There is no definite residual osseous tumor. Interval resolution of enhancement superior and inferior to the resection site which was reactive. There is mild dorsal epidural enhancement from the T9 to T11 levels which may represent postsurgical change. There is no evidence of abscess. There is interval resolution of the left pleural effusion.The vertebral column alignment is within normal limits. The vertebral body and disc space heights are otherwise preserved. The spinal cord displays normal signal and morphology with the conus terminating at L1.
1. Evolution of postsurgical changes from T6 to T9, including left T7, T8 and T9 hemilaminectomies and resection of the left T8 pedicle, without definite evidence of residual or recurrent tumor. 2. Decrease in previously seen epidural enhancement superior and inferior to the resection site which represented reactive change. Minimal residual epidural and soft tissue enhancement at the resection site may represent postsurgical change.
