Female, 56 years old, with grade 2 astrocytoma, off therapy. The expansile T2 hyperintense tumor asymmetrically involving the right aspect of the cervical cord shows no significant change in size and morphology. As before, the lesion spans from C4 through T1 and measures approximately 15 x 12 mm in the axial plane. A faint tract of T2 hyperintensity within the left lateral aspect of the cord at these levels is also unchanged. There may be minimal faint enhancement within the tumor but this is equivocal. Postoperative findings are redemonstrated consistent with lower cervical laminectomies.The expansile T2 hyperintense mass asymmetrically involving the left aspect of the spinal cord from T4 through T8 is also redemonstrated showing no significant interval change in size or extent. The lesion continues to measure up to 12 x 9 mm in the axial plane. One or two small foci of enhancement at the T5 level are unchanged. No new cord lesions are detected.Marrow signal changes are evident consistent with radiotherapy. Enhancement within the T2, T3 and T4 vertebral bodies is similar to that seen on the prior examination and nonspecific but potentially related to therapy. Mild scattered degenerative disc disease is evident without change. Vertebral body heights are preserved.
Spinal cord astrocytoma involving the cervical and thoracic regions is redemonstrated showing no significant interval change in size, morphology or signal characteristics.
