25-year-old female status post multilevel thoracic laminectomy and resection of 2 large dorsolateral meningiomas, along with pedicle screw fixation fusion in 2012. The patient is now experiencing back pain. Redemonstrated are changes from previous thoracic spine surgery with pedicle screw placement of a right-sided T8, T9, T11 and T12 an interconnecting rod as well as laminectomies at T8 through T10.Redemonstrated is an extra-axial mass located at a T6-7 vertebral body level along the right posterior lateral aspect of the spinal canal which measures5 x 8 mm axial dimensions and 14 mm in length (previously 5 x 8 mm axial dimensions and 12 mm in length) minimally changed in craniocaudal direction. As before, there is no associated cord abutment or compression.Redemonstrated is a small focus of dural thickening is located along the left lateral thecal sac at the T9/10 level measuring 5 x 3 mm in axial plane, difficult to measure in the sagittal plane given its small size. This finding is unchanged.Redemonstrated is a third tiny focus of dural thickening is located along the left anterolateral thecal sac at the T10 level measuring 4 x 2.5 mm in axial plane, difficult to measure in the sagittal plane given its tiny size. This finding is unchanged.A previously demonstrated subtle cord morphology change at the T10/11 approximate level (best seen sagittal T2 series 1101 image 8 and axial T2 series 801 image 11) is unchanged. This appears as a subtle flattening of the anterior cord although there is no discernible lesion or focus of enhancement to account for this, specifically there are no MR evident membranes to suggest formation of an arachnoid cyst or other postprocedural septation. This is of uncertain etiology or significance.Focal T2 hyperintensity within the spinal cord at T10 with associated loss of spinal cord volume is again noted and not significant changedThe thoracic vertebral bodies are appropriate in the overall alignment and height. There is no compromise of thoracic spinal canal or exiting nerve roots.
1.No change in the size of the extra-axial mass presumably representing meningioma at the T6-7 level.2.No change of a small focus of dural thickening is located along the left lateral thecal sac at the T9/10 level.3.No change of a third tiny focus of dural thickening is located along the left anterolateral thecal sac measuring 4 x 2.5 mm in axial plane4.No change of T2 signal hyperintensity within the spinal cord associated with cord atrophy and at the prior locations of the patient's tumor presumably representing myelomalacia.
