Malignant neoplasm of spinal cord [192.2], Reason for Study: ^Reason: hx cervical fibrous tumor w/ Atypical features. F/u 6 months for growth History: surveillance imaging for growth Plaque like enhancing mass on the posterior aspect of the T1 vertebral body is now measured about 29mm x 11.7mm x 9.4mm which was about 22.4mm x 9.7mm x 6.9mm showing interval increase in size.Accordingly external compression toward left side of spinal cord and thecal sac has been aggravated since prior scan.At the level of T1-T2 left side neural foramen, there is low signal intensity lesion on the left ventral aspect of the spinal cord extending toward the left side neural foramen. This lesion does not show any evidence of enhancement (series 1201, image 8/48) and shows low signal intensity on both T1 and T2 weighted images indicating fibrous tissue or non enhancing portion of the tumor mass. Comparing to prior scan, this lesion does not show any significant interval change.Prior laminectomy at the level of cervicothoracic junction, vertebral body signal changes due to prior radiation and various degreed enhancement of vertebral bodies and posterior compartments on C3 and skull base show no significant interval change. Spinal cord signal intensity appears to be normal. There is normal cervical lordosis. The cervical spine alignment is anatomic. The vertebral body height is preserved. Intervertebral discs show dessication of discs at the level of C34, C45 and C56 without showing evidence of disc herniation.
1. Interval increase in size of T1 level extradural enhancing mass with increased mass effect toward spinal cord as described above.2. No abnormal spinal cord signal intensity.
