Male, 71 years old, status post T1 corpectomy and fusion. Postoperative findings are seen compatible with interval T1 corpectomy with anterior instrumented fusion from C7 through T2. Evidence of more remote laminectomy is also seen involving the cervicothoracic junction. The previously seen left ventral epidural enhancing lesion at T1 has been resected and there is no evidence of any residual intraspinal enhancing tissue at this location. Previously seen spinal canal narrowing and mass effect upon the spinal cord have also been relieved. The cord remains chronically thinned at this location and there may be minimal residual cord T2 hyperintensity though this is equivocal.Nodular, T2 hypointense and mildly enhancing soft tissue remains evident within the left lateral paraspinal tissues at C7 and T1. This tissue measures up to 30 x 25 mm (image 21 series 12), showing no significant change from the prior exam.No new epidural lesions are suspected. The spinal canal is patent throughout. Elsewhere, the spinal cord shows normal morphology and signal characteristics.Spinal alignment is anatomic. Outside of the operative region, vertebral body height and morphology are within normal limits. No new or concerning marrow signal abnormality is detected.
1.Interval resection of the previously seen plaque-like ventral epidural enhancing lesion at the T1 level. Spinal canal narrowing and mass effect on spinal cord at this level have been relieved. No definite evidence of any residual intraspinal lesion is seen.2.Nodular soft tissue remains evident within the left lateral paraspinal tissues contiguous with the C7 and T1 vertebral bodies. This tissue has not significantly changed in size from the prior examination and may represent an extraspinal component of the original intraspinal lesion.
