Obstructive Hydrocephalus

These are the cranial CT scans from a patient with a recent left cerebellar infarct arrow_1. Due to the significant cytotoxic oedema as a result of the cerebellar infarct, the fourth ventricle is being compressed arrow_4, thus obstructing the normal CSF flow. The CT scan shows features of obstructive hydrocephalus and there is dilatation of the third ventricle arrow_5 (now appears ovoid compared to its usual “slit-like” appearance) as well as the temporal horn of the lateral ventricles arrow_6. The occipital horns of the lateral ventricles are also dilated arrow_7.
