Large right cerebral convexity acute subdural hematoma measuring up to 19 mm in depth. Small left acute SDH with maximum thickness of 4 mm.
Effacement of the adjacent cortical sulci and right lateral ventricle with associated subfalcine herniation and leftward midline shift of 10 mm. No evidence of ACA infarction. No transtentorial or tonsillar herniation. No hydrocephalus.
Large left retrobulbar hematoma, abutting the superior and lateral orbital walls within the extraconal fat planes, measuring 38 x 25 x 19 mm. This depresses the extraocular muscles and globe, resulting in significant proptosis. The globe is intact. Large left periorbital hematoma with laceration. The right orbit is normal. No orbital fracture.
No skull fracture elsewhere.
The paranasal sinuses and mastoid air cells are well-aerated. No skull fracture.
