Clinical question: h/o neurocytoma; preop planning for resectionSigns and Symptoms: preop planning The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a midline mass present along the falx measuring 45x19mm axial dimensions. It contains foci of high signal on T1 centrally and is peripherally hypointense on T2 and T1. There is some associated signal hyperintensity within the cingulate sulcus.A focus of encephalomalacia is present along the left superior frontal gyrus.The patient is status post left frontal craniotomy.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 demonstrate small opacities. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Examination was performed for the purpose of stereotactic guidance during surgery. There is a midline mass present which has hemorrhagic components within it and is associated with adjacent siderosis within the cingulate sulcus.2.There is encephalomalacia along the left superior frontal gyrus.3.Patient status post left frontal craniotomy
