Benign neoplasm of cerebral meninges. Brain lesion. Preoperative planning for brain tumor resection The CSF spaces are appropriate for the patient's stated age with no midline shift. There is redemonstration of an extra-axial mass adjacent to the medial aspect of the left precentral gyrus which measures 22 x 18 mm sagittal dimensions on the current exam and is unchanged since the prior exam. Findings suggest infiltration of the lesion to the dura and possibly into the superior sagittal sinus.There is diffuse pachymeningeal enhancement presentNormal 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.Examination is performed for the purpose of stereotactic guidance. This is a limited exam.2.There is redemonstration of an extra-axial mass adjacent to the left precentral gyrus which is suspected to infiltrate into the superior sagittal sinus.
