Headache for past 3 months behind the right eye, on OCP. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. There is a 5 mm wide cyst within the pineal gland. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. There is a prominent left posterior condylar vein that may slightly indent the left lateral cerebellar hemisphere. The major cerebral flow voids are otherwise intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. No evidence of intracranial hemorrhage, mass, or acute infarct. 2. A prominent left posterior condylar vein likely represents an anatomic variant, but can be a manifestation of raised intracranial pressure, although there are no other findings to suggest intracranial hypertension or venous sinus thrombosis.
