There is no evidence of intracranial hemorrhage, mass or edema. The ventricles are midline and demonstrate normal morphology and volume. Increased density in the suprasellar cistern may be due to partial volume averaging, though correlation with MRI may be helpful to further evaluate as clinically indicated.The calvaria and skull base are radiographically normal. There has been interval partial opacification of the right mastoid air cells and right frontal sinuses, with the remainder the visualized paranasal sinuses are normally pneumatized.
