Previous T9-T11 decompressive laminectomy again identified. There is a homogeneously enhancing slightly T2 hyperintense circumscribed extradural mass occupying the left half of the spinal canal and extending through the left T9/T10 exit foramen. At the superior extreme of the mass, a tiny enhancement extends along the inferior margin of the left T 8/9 exit foramen. The component within the spinal canal has maximal axial dimensions of 14.5 x 15.5 mm and a craniocaudal extent of 29 mm.
A separate smaller enhancing lesion located anteriorly in the spinal canal immediately inferior to the main lesion measures 8 x 7 x 4 mm, and appears to be intradural.
The spinal cord is displaced into the right side of the spinal canal, with a distorted contour but no compression. There is no convincing intrinsic cord signal abnormality.
At the level of the T7 vertebral body, there is a prominent enhancing vessel applied to the left dorsal aspect of the cord, of dubious clinical significance.
No change to the enhancing T 2 hyperintense lesion within the left T10 transverse process, most likely be a haemangioma.
Small T5-6 and C6-7 left paracentral disc protrusion is and right T8/T9 paracentral disc protrusion again noted.
Conclusion: Recurrent meningioma occupying the left side of the spinal canal at T9 level with extension into the left T9/T10 and to a lesser extent T8/9 intervertebral foramina, displacing and distorting the cord without compression or intrinsic cord signal abnormality. There is a smaller anterior intradural component just below the main lesion.
