 MRI brain:Redemonstrated are post surgical changes in the right temporal region with encephalomalacia of the right anterior temporal lobe which is not significantly changed. There is no change in the FLAIR signal surrounding the surgical defect end the right temporal lobe, insula, and external capsule. An additional punctate focus of increased FLAIR signal immediately superior to the surgical cavity in the inferior gyrus of right frontal lobe as well as a thin, linear FLAIR abnormality in white matter along right lateral ventricle are also unchanged. There is mild mucosal sinus thickening in the involving the ethmoid air cells and minimally involving the maxillary sinuses, left greater than right.The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift or mass effect. There is no acute diffusion abnormality. No extra-axial fluid collection is identified. Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. MRI Orbits:No abnormal mass is seen. No abnormal signal intensity is evident. The optic nerves are normal in size and signal. Intensity, and are symmetric bilaterally. No retrobulbar mass, chiasmatic mass, or parasellar abnormality is seen. Extraocular muscles are unremarkable.
1.No discrete findings to explain the patient's visual field defect.2.Stable postsurgical changes in the right temporal region and stable surrounding FLAIR signal abnormality consistent with gliosis.
