Gbm (glioblastoma multiforme62 years Female (DOB:10/30/1953)Reason: preop planning for crani History: none- preopPROVIDER/ATTENDING NAME: BAKHTIAR YAMINI BAKHTIAR YAMINI The patient status post left occipital craniotomy. There is redemonstration of a 23 by 35mm axial dimension irregularly-shaped ring-enhancing lesion associated with surrounding T2 signal hyperintensity within pattern of vasogenic edema. There is also subependymal enhancement in the adjacent occipital horn of the left lateral ventricle.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.Left occipital lobe mass associated with the vasogenic edema suspicious for an aggressive neoplasm versus radiation necrosis. This mass abuts the occipital horn of the left lateral ventricle and is associated with some subependymal involvement raising the question of possible CSF spread. This has not changed substantially since 9/28/2016. Please refer to the recent MRI exam for further comment.2.Please note that this examination performed for the purpose of stereotactic guidance during surgery. It is limited in its diagnostic ability.
