Persistent headaches. There is colpocephalic appearance of the lateral ventricles with enlargement of the occipital horns and atria with mild adjacent FLAIR hyperintensity. There is mildly diminished supratentorial white matter, particularly involving the periatrial white matter. There is associated mild thinning of the posterior aspect of the corpus callosum. No evidence of hydrocephalus. No intracranial mass or mass effect. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved. Sella and orbits are essentially within normal limits with possible small Rathke's cleft cyst involving the pituitary. Paranasal sinuses and mastoid cells are clear. Bone marrow signal and extracranial soft tissues are within normal limits.
1. No intracranial mass or mass effect.2. Colpocephalic configuration of the ventricles and diminished periventricular white matter, findings which may be related to periventricular leukomalacia related to perinatal insult. 3. Tiny area of hypoenhancement involving the posterior inferior aspect of the pituitary gland which may represent a small Rathke's cleft cyst.
