Intraventricular mass lesions of the brain

Intraventricular tumours represent a diverse group of lesions, some of them infrequent. with a wide variety of radiological features. Determination of their precise aetiology or origin can be difficult. Nevertheless, consider ing patient's age, location within the ventricles, and some specific radiol ogical features, the radiologist should be able to narrow down the differen tial diagnosis. This paper reviews the characteristic radiological appearan ces of the diverse intraventricular lesions emphasising its differential di agnosis.
