CT HEAD WITHOUT CONTRAST:
CLINICAL HISTORY: 30 years of age, Male, progressive altered mental status and headache.
FINDINGS:
Visualized paranasal sinuses: Mild opacification of the left posterior ethmoid air cells.
Mastoid air cells: Clear.
Bones: No focal abnormality.
Additional comment: None.
IMPRESSION:
1. Edema with mass effect in the anterior right temporal lobe and right mesial temporal lobe, with focal hemorrhages in the right
mesial temporal lobe and overlying the right uncus. No definite vascular abnormality seen to account for hemorrhage. Given rapid
development of edema in the temporal lobe and associated hemorrhage, encephalitis, specifically HSV encephalitis, is primary
consideration. Venous thrombosis could also have this appearance however no thrombosed vein is identified. Further evaluation with MRI to better characterize parenchymal findings and look for possible
contralateral involvement is recommended.
