Male, 28 years old, neurofibromatosis type I with extensive neck tumors. Cervical:Innumerable subcutaneous and paraspinal T2 hyperintense masses are again seen compatible with neurofibromas. There has been no significant interval change in the overall size or number of these lesions.Also stable are foraminal neurofibromas which are present bilaterally at every level. The largest of these occupies the right C5-6 foramen measuring 30 x 20 mm, previously 30 x 20 mm. This lesion, and several others to a lesser degree, do extend into the spinal canal with resultant canal narrowing and some deformation of the spinal cord, findings which are overall unchanged. No definite evidence of cord edema is seen.Again seen is evidence of laminectomy from C4 through C7. A focal kyphotic angulation of the spine is seen at C6-7, unchanged. Alignment is unremarkable. Marrow signal characteristics are within normal limits.Lumbar:Innumerable subcutaneous and paraspinal neurofibromas are redemonstrated, without significant interval change. Neurofibromas within or adjacent to all of the visualized neural foramina are also grossly unchanged. The nerve roots of cauda equina remain diffusely thickened likely secondary to the presence of numerous lesions. A dominant lesion situated within and effacing the right lateral recess at the L4-5 level measures 11 x 10 mm, previously 11 x 9 mm. This lesion results in moderately severe encroachment upon the thecal sac and some crowding of the cauda equina.Spinal alignment is anatomic. Vertebral body morphology and signal characteristics are within normal limits.
1.Stable neurofibromas in the cervical region. Several of these encroach upon the spinal canal with resultant canal stenosis and cord deformation, most notably at C5-6 and C6-7.2.Stable neurofibromas in the lumbar region. A dominant lesion within the right lateral recess at L4-5 continues to cause moderate sac encroachment.
