Diagnosis: Unspecified convulsions Malignant neoplasm of brain, unspecified Unspecified convulsions Malignant neoplasm of brain, unspecified MRI brain:There is a 12 x 23 mm axial dimension mass located at the medial aspect of the right temporal lobe which is homogeneously high signal on T2 and homogeneously low signal on T1. There is no associated contrast enhancement. It displaces the right posterior communicating artery medially and protrudes into the suprasellar cistern along its posterior aspect. It is within a millimeter of the infundibulum of the pituitary gland. It impresses upon the right cerebral peduncle and also displaces the basal vein of Rosenthal superiorly. It drapes over the tentorium. The right optic tract is displaced superiorly. Compared to the previous exam from 8/14/2015 and has not changedNormal 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.MRI pituitary:The pituitary gland is appropriate in overall height and morphology. The infundibulum of the pituitary gland is midline. No suprasellar or intrasellar mass is identified. The cavernous sinuses are intact bilaterally.
There is redemonstration of a right medial temporal lobe mass which is stable compared to the prior exam and is known to represent an exophytic pilocytic astrocytoma. It is stable compared to the prior exam.
