51 yo female with C2 cavernoma. Surveillance. Cervical Spine: Focus of increased T2 signal abnormality with hemosiderin rim in the ventral left cervical cord at the C2 level measures 5 x 6 x 7 mm (AP x TR x CC), and unchanged allowing for differences in technique. This focus demonstrates associated T1 hyperintensity as well as mild enhancement and unchanged.Cervical spine alignment is anatomic. Signal intensity and morphology of the vertebral bodies are within normal limits. Mild degenerative changes are again seen with central disk protrusion at the C3-C4 level with mild flattening of the ventral cord. No associated cord signal abnormality. There is mild left neural foramina stenosis on the left at C3-C4 related to facet arthropathy and uncovertebral hypertrophy. Mild disc bulge at C6-7 also unchanged without significant spinal canal or neural foraminal stenosis. T1 hyperintense focus at the T2 vertebral body compatible with hemangioma.Brain:No intracranial mass or mass-effect. No lesions to suggest brain cavernous malformation. No intracranial hemorrhage. No restricted diffusion. The ventricles are within normal limits in size and configuration. Several foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with mild chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age. There is diffuse mucosal thickening involving the left maxillary sinus.
1. Compared to 6/29/2012, no significant change in size of left ventral C2 lesion consistent with cavernous malformation. 2. Mild degenerative changes including central disc protrusion at C3-4 with mild spinal canal stenosis and mild left neural foraminal stenosis is also unchanged.3. Brain parenchyma is essentially unremarkable for age. No brain cavernous malformations.
