Suspected viral mmeningitis. A lumbar puncture was done which revealed an elevated opening pressure. Brain MRI: There is a subcentimeter nodular lesion with susceptibility effect in the left corona radiata with an adjacent small development venous anomaly. There is no evidence of cerebral abscess or abnormal leptomeningeal enhancement. There is no evidence of intracranial hemorrhage or acute infarct. There is flattening of the pituitary gland. The ventricles and basal cisterns are normal in size. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.Brain MRV: There is apparent focal constriction of the bilateral transverse sinuses. There is no evidence of cerebral venous sinus thrombosis.Orbits MRI: The bilateral globes and ocular adnexa are unremarkable. There is no evidence of abnormal intraorbital enhancement or mass lesions.
1. Small cavernous malformation in the left corona radiata with an adjacent small development venous anomaly.2. No evidence of cerebral abscess or abnormal leptomeningeal enhancement.3. No evidence of cerebral venous sinus thrombosis.4. No evidence of orbital lesions.5. Flattening of the pituitary gland and apparent focal constriction of the bilateral transverse sinuses can be manifestations of elevated intracranial pressure.
