Lateral ventricle visualization during brain scanning with Tc-DTPA.

The visualization of the cerebral ventricles during a brain scan is a relatively rare possibility. The authors had the opportunity of observing four cases. They report them and discuss the 19 cases reported in world literature. There were, in order of importance, 12 cases of ventriculitis, 3 of non tumorous intraventricular erruptions, 2 of tumours infiltration, 1 metabolic encephalopathy and one unexplained case. It is concluded that the visualization of the ventricule during a brain scan (particularly the early visualization) is a good etiological indicator of ventriculitis.
