There are no intracranial enhancing lesions. No evidence of acute or chronic intracranial hemorrhage is seen. Mild prominence of the CSF along the superior surface of the cerebral hemispheres is unchanged and may reflect underlying cerebellar volume loss or subdural effusions. The ventricular system is normal in size and morphology. Minimal left frontal periventricular white matter T2 hyperintensity is seen, a nonspecific finding. Patchy opacification of the mastoid air cells is seen, right more than left. Opacification of the right frontal sinus and the ethmoid air cells is seen with mucosal thickening and minimal fluid in the left sphenoid sinus.
1.No acute intracranial abnormality.2.No intracranial findings to account for the patient's symptoms.3.Evidence of mucosal inflammation is seen in the paranasal sinuses and mastoid air cells. Correlation with clinical signs of sinus or mastoid infection is suggested.
