Intracranial Cavernous Hemangioma

Intracranial cavernous hemangioma is one of vascular malformations composed of thin walled sinusoidal spaces lined with endothelium. The authors described 7 cases of cavernous hemangioma that were verified histologically and 5 lesions that were diagnosed only with symptoms, radiological and magnetic resonance imaging(MRI) findings. The clinical features are as follows:7 patients had seizures, 3 focal neurological signs and 2 intracaranial hematomas. Computed tomography(CT) usually demonstrated nodular or irregular hyperdense lesions without significant mass effect. MRI usually revealed central area of mixed signal intensity and peripheral rim of low signal intensity. Angiography usually showed an avascular area or normal angiographic appearance. The combination of a clinical history with CT, angiography and MRI findings would suggest cavernous hemangioma. Four epilepsy patients underwent surgical procedures, resulting in improved seizure control and/or lessened neurological deficit.

Stereotactic Removal of the Third Ventricle Colloid Cyst

Colloid cyst of the third ventricle is rare intracranial lesion. It has been estimated that they comprise approximately 0.55% of all tumors of the brain. A new interest has been developed in this lesion, which is completely benign histologically but, because of its deep and strategic location, poses a difficult therapetic problem. The contrast between the histological benignancy and the risk of morbidity and mortality associated with often surgical exploration and removal has led to alternative procedures. We reported here a 33-year-old male patient with colloid cyst of the third ventricle presenting with headache and vomiting. Who was treated by stereotacic removal utilizing CRW stereotactic system and followed up post-operatively for more than 3 years.
