Spinal cavernous malformation, yearly surveillance. Again seen is a hemorrhagic spinal cord lesion at the T10 vertebral body level predominantly involving the left aspect of the cord and measuring approximately 8 x 7 mm in the axial plane, which is unchanged. Hemosiderin staining extending slightly superiorly and inferiorly is also unchanged. There is no new surrounding edema appreciated on the current exam. The thoracic vertebral bodies are appropriate in the overall alignment and height. There is disc desiccation at the T9-T10 level with a right-sided disc protrusion which effaces the right lateral aspect of the thecal sac at this level. The disc protrusion is minimally increased in the interval. No significant spinal canal or neural foraminal stenosis at this level or elsewhere in this thoracic spine.
1. Compared to 11/24/2014 and 11/25/2013, there is no significant change in hemorrhagic intramedullary lesion centered at the left T10 level consistent with cavernous malformation.2. Small disc protrusion at the right T9-T10 level is minimally increased in the interval but without significant associated spinal canal stenosis.
