Findings:
There is a hyperdense extra-axial, dural based appearing mass containing multiple calcifications overlying the left parietal mid convexity. The mass measures 1.6x2.8x2.0cm. It causes mild surrounding mass effect and no vasogenic edema. There is subtle thickening of the inner cortex of the adjacent skull. There is mild white matter disease consistent with small vessel ischemic changes. There is a 2mm inferior outpouching of the left ICA in the cavernous sinus distal to the ophthalmic artery origin with a broad-based neck. The posterior communicating arteries are hypoplastic/absent. The lenses are replaced bilaterally. There is minimal mucosal thickening within the anterior ethmoid air cells. There is a small osteoid osteoma in the inferior right frontal sinus. There is a 3 mm polygonal shaped peripheral pulmonary nodule in the right lung apex with linear extension to the pleura, which may represent nodular scarring. A calcified granuloma is also seen in the anterior right lung apex. There is advanced multilevel degenerative osteochondrosis of the cervical spine which is most severe at the level of C4-5 with posterior osteophytes causing mild anterior spinal canal stenosis.

Impression:
There is a 2cm hyperdense, enhancing, and partially calcified extra-axial mass overlying the parietal lobe most likely representing a meningioma. There is a tiny saccular aneurysm inferiorly projecting form the left cavernous ICA.
