Patient Data

Age: 40 years.
Gender: Male

intraventricular lipoma


A lobulated hypodensity of fatty attenuation is seen in the trigon of the left lateral ventricle and extends to the adjacent part of the third ventricle. Its appearance suggests choroid plexus lipoma. An associated slight mass effect is seen in the form of the slight mid-line shift to the right side by about 5 mm.

Case Discussion

Choroid plexus lipomas like intracranial lipomas are usually discovered incidentally at the trigone of the lateral ventricles when imaging is obtained for other indications. Choroid plexus lipomas are not a true neoplasm but are rather a form of congenital malformation.
