Angiosarcoma, post resection of epidural mass at T5-7 in 04/2011 followed by adjuvant radiation therapy. Absence of intravenous gadolinium again slightly limits evaluation. Again seen are postoperative changes of laminectomy and epidural tumor resection at T5 through T7 levels. Mild thoracic kyphosis is similar to prior. Epidural scarring without any significant mass effect on the thecal sac remains similar to prior exam. There is no evidence of spinal stenosis at this level. There is no detectable signal abnormality or change in the caliber of the cord.There is marrow signal replacement with low T1 and high T2 signal involving the left aspect of T5 and T6 vertebral bodies posteriorly extending into the left pedicle and surrounding the neural foramina at T5-T6 and T6-T7 levels similar to prior. Also similar to prior exam there is a centrally located disk protrusion at T8-T9 level with subtle indentation on ventral aspect of the cord. No new marrow signal abnormality or new epidural mass.
1. Stable post-treatment changes with unchanged marrow signal abnormality involving the left T5 and T6 posterior lateral vertebral bodies, pedicles, and neural foramen. Lack of intravenous gadolinium limits evaluation; however, findings are compatible with stable treated tumor. No new epidural mass. No findings to suggest tumor progression.2. Unchanged central disc protrusions at T5-6 through T8-T9 with effacement of CSF space and subtle cord impression at T8-9.
