Diffuse closure of the sulci has not changed since the previous examination. Relatively, gray-white differentiation continues to be preserved. Dilatation of the lateral ventricles remain mild and not significantly changed. The third ventricle remains largely compressed. The fourth ventricle is compressed. The third ventricle is also compressed the less severely. This has not changed since the previous examination. Crowding of structures at the level of foramen magnum with alteration of the CSF containing spaces at that level remain unchanged. The extent of cerebellar tonsillar descent is better assessed by MRI if clinically warranted. The ambient cisterns remain closed. There is no evidence of acute ischemia or hemorrhage. The osseous structures are unremarkable. The pituitary gland is preserved in volume. The sella turcica is not enlarged. The paranasal sinuses are clear. Opacification of the mastoid air cells is unchanged.
