 The pituitary gland is not enlarged and there is no evidence of gross mass lesions, although the assessment is limited by the lack of intravenous contrast. The pituitary stalk lies in the midline. The suprasellar cistern, optic chiasm, cavernous sinuses and intracranial portions of the optic nerves appear to be intact. There is no evidence of intracranial hemorrhage or acute infarct. However, there are scattered T2 hyperintense lesions in the periventricular and subcortical white matter, a few of which are flame shaped in configuration. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. There is minimal mucosal thickening of the bilateral maxillary sinuses.
1. Limited non-contrast examination without evidence of gross mass lesions in the pituitary gland. 2. Several lesions in the periventricular and subcortical white matter likely represent demyelinating lesions, although these are incompletely characterized due to the lack of intravenous contrast.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
