Status post resection of skull based meningioma on 4/8/14: 6 month follow up residual tumor. There has been interval evolution of postoperative findings related to right pterional craniotomy for resection of a planum sphenoidal tumor. There is persistent mild residual dural thickening and enhancement in the right paraclinoid region with a punctate nodular focus that extends into the right optic nerve canal with apparent mild impingement upon the right optic nerve. There is mild atrophy and diffuse T2 hyperintensity of the right optic nerve as well. The orbital contents are otherwise unremarkable.
Postoperative findings with small amounts of residual tumor in the right paraclinoid region with extension into the right optic nerve canal with evidence of associated chronic compressive right optic neuropathy.
