30 years, Female, new onset headache, evaluate for evidence for idiopathic intracranial hypertension?. Brain parenchyma appears within normal limits. No significant parenchymal signal abnormality. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Slightly prominent linear structure is seen involving the right occipital lobe which may represent a developmental venous anomaly. Major flow-voids are preserved.Sella and orbits are grossly unremarkable without significant distention of the optic nerve sheaths or significant flattening of the pituitary gland to indicate intracranial hypertension. Cerebellar tonsils are in normal position. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
Brain MRI without contrast is within normal limits for age. There is no specific evidence of intracranial hypertension, although if there is high clinical suspicion consider correlation via lumbar puncture.
