A review of 116 cases of coexistent brain tumours and intracranial arterial aneurysms is made. The cases were collected from the literature, personal experience (8 cases) and different neurosurgical centres all over the world. According to the literature the general incidence of intracranial arterial aneurysms does not seem to be higher in brain tumours(More)
Arteriovenous malformations or fistulae shunting arterial blood from branches of the external and internal carotid and vertebral arteries into the transverse-sigmoid sinus may produce different clinical syndromes. The literature is reviewed with 96 patients including six personal cases. Usually these malformations have a congenital origin and only in 4% of(More)
Tumours of the pineal region and posterior part of the third ventricle are rare in European and American series (0.5 to 1% of space-occupying lesions). Personal experience is usually limited and thus cooperative studies or critical reviews of reported cases are necessary to establish therapeutic criteria. We have studied 50 cases from our own material of(More)
Sixty-five personal cases of cerebellar hemangioblastomas plus others from the literature making a total of 539 cases are reviewed regarding their clinical, biological and surgical aspects. A variable genetic blastomatous growth potential seems to determine the individual biological behavior of these tumors. Retinal angiomatosis, family incidence,(More)
Computerized Axial Tomography (CAT) has proved extremely useful for the diagnosis of cerebral cysticercosis. The calcified small, multiple, and scattered cysts provide a typical image on CAT. The collection of non-calcified cysts in the subarachnoid spaces (racemose form) or in the ventricles may produce areas of low density similar to that of the(More)
