These are the cranial CT scans from a patient with a recent left cerebellar infarct . Due to the significant cytotoxic oedema as a result of the cerebellar infarct, the fourth ventricle is being compressed , thus obstructing the normal CSF flow. The CT scan shows features of obstructive hydrocephalus and there is dilatation of the third ventricle (now appears ovoid compared to its usual “slit-like” appearance) as well as the temporal horn of the lateral ventricles . The occipital horns of the lateral ventricles are also dilated .
