Reason: change in brain lesions, pituitary? History: daily headaches. History of right carotid body. Ganglia,. There is a 1.5 cm lesion in the right frontal lobe with extensive susceptibility compatible with a prior hemorrhagic infarct. Surrounding FLAIR signal in the right centrum semiovale is slightly increased posteriorly. No evidence of new hemorrhage.Areas of increased T2 signal with associated susceptibility and mildly increased T1 signal in the right occipital lobe are unchanged and suggestive of laminar necrosis secondary to prior ischemia.No new areas of abnormal signal. No evidence of restricted diffusion. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. Absence of flow void in the right internal carotid artery with dilatation of the left internal carotid artery appears similar to the prior exam. Prominent ventricles may reflect a mild degree of volume loss. The orbits, skull and scalp soft tissues are grossly unremarkable. The paranasal sinuses are unremarkable. T1 hyperintense thickening along the pituitary stalk measuring 4 mm is unchanged.
1.Right frontal lobe hemorrhagic infarct with slightly increased surrounding T2 signal, within the expected progression of this lesion. 2.Right occipital laminar necrosis is unchanged.3.Absent flow-void in the right internal carotid artery is unchanged.4.Nonspecific pituitary stalk lesion is unchanged.
