Cerebral hemiatrophy

Case contributed by Dr Chris O'Donnell


Previous history of a neonatal right MCA territory infarction. Now left hand numbness and seizure. No other neurological deficit.

Patient Data

Age: 25
Gender: Male

Generalized assymetry (reduced size) of the right hemicranium and brain with more focal atrophy in the right middle cerebral artery territory with adjacent gliosis. Right cerebral peduncle is also smaller. Brain otherwise is normal.

Case Discussion

Remarkably due to the plasticity of the brain, this patient had no discernible neurological deficit. The area of atrophy and gliosis fits with old MCA territory infarction yet the whole right cerebral hemisphere is smaller than the left. The cranium on the right has also not grown to the size of the left as its contents are smaller.
