[Meningioma of the anterior part of the 3rd ventricle. Clinical case].
Although intraventricular meningiomas are rare, the location within the third ventricle is very uncommon. A case of a meningothelial meningioma of the anterior part of the third ventricle is presented. Clinical features disclose both signs of intracranial hypertension and signs related to the anterior third ventricle location. Using a transfrontal transventricular approach the tumor was totally removed and the follow up was uneventful. For determining the best operative approach, consideration of a number of principles is mandatory: 1. A precise angiographic study, a computerized tomography, magnetic resonance imaging with coronal and sagittal reconstructions to evaluate the lesion and the ventricles size; 2. Excessive retracted cerebral tissue must be avoid as like as to minimize incision in cerebral cortex, corpus callosum, lamina terminalis or fornicial raphe; 3. For a good excision of the lesion it is better to avoid excision "en bloc" with early coagulation of the feeding arteries.
