64 years Female (DOB:8/5/1951)Reason: pre-op planning History: pre-op planningPROVIDER/ATTENDING NAME: PETER C WARNKE PETER C WARNKE There is an extra-axial contrast enhancing mass present which abuts the falx and is medial to the right frontal lobe. It has a broad-based the dura and measures 46 x 39 mm axial dimensions. It is heterogeneous on signal intensity on all pulse sequences. It has a low signal center. There is susceptibility effect within much of the lesion. Within the white matter in the adjacent right frontal lobe there is T2 and FLAIR signal hyperintensity suggestive of vasogenic edema. There is mass effect present with distortion of the right lateral ventricle and corpus callosum. There is also shift of the falx to the left of midline x 10 mm. An 8 mm component of the mass protrudes across midline along the anterior and superior aspect of the mass.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
There is a large right parafalcine extra-axial mass present adjacent to the right frontal lobe associated with compression of adjacent brain parenchymal structures as well as some vasogenic edema. Most likely this represents a meningioma.
