Preop planning for tumor biopsy. This is a limited MRI of brain for preoperative planning. There is redemonstration of abnormal T2 signal within the right greater than left basal ganglia and right anterior thalamus. There is also abnormal T2 signal within the right cerebral peduncle, which extends caudally to the level of upper pons. There is no abnormal intracranial enhancement. Compared to 5/27/2015, there appears to be decrease in T2 hyperintensity within the right basal ganglia as well as resolution of enhancement. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift. The skull and extracranial soft tissues are unremarkable. There is a small mucous retention cyst in the left maxillary sinus.
Limited study MRI of the brain for preoperative planning. Compared to MRI brain dated 5/27/2015, interval decrease in T2 signal within the right basal ganglia as well as resolution of right basal ganglia enhancement is noted.
