A 45-year-old man has had a severe headache for a week. Physical examination reveals papilledema on the right. A head CT scan reveals a marked right to left midline shift. An MRI scan demonstrates a 6 cm enhancing mass lesion in the right parietal region with marked surrounding edema. He develops a dilated pupil on the right and soon thereafter loses consciousness and dies. At autopsy, which of the following lesions is most likely to be found?
A Superior sagittal sinus thrombosis
B Right cerebellar hemispheric hemorrhage
C Pontine hemorrhages
D Thrombosis of the posterior cerebral artery
E Diffuse subarachnoid hemorrhage

the ans is C
pontine haemorages-The brain swelling leads to herniation, which damages small perforating vessels and results in Duret hemorrhages in the pons and midbrain

I just realized that the question asked what autopsy findings would reveal and not what caused the raised ICP.
Very careless of me
