 There is a left cavernous sinus region enhancing, dural-based mass that measures up to approximately 25 mm. There is negligible mass effect upon the left medial temporal lobe and no evidence of vasogenic edema. There is prominence of the sulci and ventricles due to cerebral volume loss. There is mild nonspecific scattered periventricular and subcortical white matter T2 signal, likely due to mild age indeterminate small vessel ischemic disease. There are also punctate areas of encephalomalacia in the corona radiata bilaterally. There is no midline shift. There is no evidence of acute infarction or intracranial hemorrhage. Normal flow-voids are demonstrated in the major intracranial vascular structures. The orbits are unremarkable. The skull is intact. There is a small amount of fluid within the left mastoid air cells. There is a punctate right sphenoid sinus retention cyst.
1. Left cavernous sinus region enhancing, dural-based mass that measures up to approximately 25 mm likely represents a meningioma.2. Mild chronic small vessel ischemic disease and bilateral corona radiata lacunar infarcts, but no evidence of acute infarction.3. Diffuse cerebral volume loss.4. Nonspecific small amount of fluid within the left mastoid air cells.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
