Abstract

|
|
The literature concerning meningioma of the parasagittal and convexity is voluminous. However, the meningiomas within ventricular system are rare.
We have presented two cases of the intraventricular meningiomas which were sucessfully removed and the diagnosis was confirmed histologically.
A 44-year-old male was admitted with complaints of headache and visual disturbance for one year and one month.
On his admission clinical findings were mental confusion, bilateral papilledema and loss of vision except light perception. Pneumoventriculogram showed marked symmetrical dilatation of the lateral ventricles and filling defect in posterior half of the third ventricle. Through the right frontal lobe incision a solid mass occupying in posterior half of the third ventricle was removed.
Histological diagnosis confirmed a fibroblastic meningioma.
The other case was 10-year-old boy who was having weakness of the right extremities without headache or vomiting. Neurological findings were bilateral papilledema and weakness of the right extremities. Pneumoventriculogram outlined a spherical filling defect, 6X4X5.5 cm in size, from left lateral ventricle to right lateral ventricle and the third ventricle.
Left frontal craniotomy was carried out and removed a large tumor in the trigon of the left lateral ventricle. Histological diagnosis confirmed meningothelial meningioma.
