Reason: h/o left parasagital meningioma History: pre op planning The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 11 x 16 mm axial dimension extra-axial mass adjacent to the superior sagittal sinus just behind the right cortical vein and abutting main posterior aspect of the left paracentral lobular.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.
1.Extra-axial mass adjacent to the left paracentral lobular is a stable when compared to the prior exam2.examination was performed for stereotactic guidance
