The authors present two cases of dysontogenetic posterior fossa tumours stressing the rarity of this location and size of these tumours and the possibility of coexistence of developmental anomalies not characteristic for such lesions.
The authors present 12 patients operated upon for arteriovenous malformations located in deep structures of brain. In terms of the location, clinical course and neurological status there were three distinct groups of patients. The results of the operative treatment lead to the conclusion that the operative treatment risk is no greater than in cases of superficial AVMs, in which it is generally accepted.
The authors discuss the results of surgical treatment of 45 patients with giant intracranial aneurysms calling attention to more frequent occurrence of subarachnoid haemorrhage as the presenting signs, and to the most effective treatment method that is closing of aneurysm neck with a clip, especially in aneurysms of the internal carotid artery. Ligation of aneurysm neck, non-radical operations, other location of the aneurysm, serious condition of the patient and repeated subarachnoid haemorrhages worsen the therapeutic results.
The authors describe a rare case of large size epidermoid cyst in the lateral ventricle of the brain. Surgical treatment was successful.
