This is an axial section of the brain through the mid portion of the cerebral hemispheres. The brain had been cut without complete fixation. However the left cerebral hemisphere shows swelling with compression of the lateral ventricle mainly in the frontal area. This swelling of the left hemisphere is due to recent necrosis in the Middle Cerebral Artery distribution. The brain in the MCA area shows discoloration of the cortex and also blurring between the cortex and white matter. Diagnosis: Recent cerebral infarction in left MCA distribution.
