Migraine patient now with unrelenting headaches for 3 weeks, family history of intracranial aneurysms. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No suspicious intracranial mass or mass-effect. There is a sub-centimeter pineal cyst measuring 9 x 5 x 5 mm without significant mass-effect or suspicious enhancement. Brain parenchyma is otherwise unremarkable for age. The ventricles are within normal limits in size and configuration. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits. MRA HEAD: The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. The vertebral arteries, basilar artery, and posterior cerebral arteries also are patent with no significant stenosis. No evidence of aneurysms or vascular malformations.
1. MRI of the brain is essentially unremarkable. There is a subcentimeter pineal cyst without mass effect and of doubtful clinical significance. No suspicious intracranial masses, mass effect, or abnormal enhancement is appreciated.2. No intracranial aneurysms.
