87 years Female (DOB:2/17/1929)Reason: 87F with h/o brain aneurysm and optic neuropathy with sudden loss of color vision left eye History: sudden loss of color vision left eyePROVIDER/ATTENDING NAME: SUSAN M KSIAZEK SUSAN M KSIAZEK MRI orbits:The eyeballs are intact. No intraconal or extraconal space mass is identified. The extraocular muscles are intact. The lacrimal glands are symmetric and within normal limits in size and configuration. There is no optic nerve enhancement appreciated. The suprasellar cistern is intact There is a punctate focus of enhancement present along the posterior aspect of the pons which corresponds to a microhemorrhage identified on the 9/11/2014 MRI of the brain in can be identified on the echo planar images as a signal void..No foci of diffusion restriction are appreciated within the brain parenchyma.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries. The ophthalmic arteries are also identifiedThere is a 2.5 mm infundibulum present at the origin of the left posterior communicating artery. The posterior communicating arteries are very small.There appears to be obtaining infundibulum at the origin of the left ophthalmic artery. There is redemonstration of a slight bulge of the left internal carotid artery at the proximal ophthalmic segment and its lateral wall which is likely related to minor atherosclerosis.There is extracranial origin of the right posterior inferior cerebellar artery present.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified and is small. The vertebral arteries are similar in size.
1.There is no evidence for an intraorbital mass or other explanation for the patient's visual loss involving the left eye.2.There is a 2.5mm infundibulum present at the origin of the left posterior communicating artery.
