title: Diagnosis of lesions in the third ventricle.
abstract: The precise diagnosis of lesions occupying the third ventricle requires both clinical and radiological examinations. Laboratory tests may provide important additional information in some cases. The specific diagnosis of a third ventricle tumor, however, cannot be established without biopsy except in very rare cases. The diagnostic and differential diagnostic problems are illustrated by some examples and discussed.
