Intraventricular neurocysticerci are an uncommon occurrence and are often difficult to diagnose. They are often a cause of obstructive hydrocephalus and inflammatory reactions, which can be life threatening. Intraventricular neurocysticerci are most common in the fourth ventricle and surgical decompression of obstructive hydrocephalus is an important step in their management. However, these cysticerci are also known to migrate within the ventricular system and may cause confusion during surgery. It thus becomes very important for radiologists and neurosurgeons to be aware of this phenomenon.
