 There is an avidly enhancing extra-axial mass overlying the anterior left temporal lobe measuring approximately 4 cm. The tumor bulges into the left optic nerve canal. There is associated mass effect and extensive vasogenic edema in the adjacent left temporal lobe. There is a 6 mm of left to rightward midline shift and left uncal herniation. There is a small developmental venous anomaly in the left midbrain. There is no evidence of acute intracranial hemorrhage or infarction. The skull appears to be grossly intact. The orbital contents are grossly unremarkable. There are skin-based fiducial markers.
Left middle cranial fossa mass that measures up to 4 cm with vasogenic edema in the compressed anterior left temporal horn likely represents a meningioma. The tumor bulges into the left optic nerve canal and there is 6 mm of midline shift to the right.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
