[Diagnostic pitfalls in stereotactic biopsy].
Between October 1998-August 2000, 65 patients were diagnosed, and underwent stereotactic biopsy of brain lesions. Procedures were performed with the Riechert-Mundinger stereotactic device. The diagnosis was made intra-operatively, by examination of cytological smears. The initial diagnosis was confirmed after H&E, and selective stains, as well as immunohistochemical examinations of paraffin specimens. The method applied makes possible to obtain a reliable, and precise morphological diagnosis in the majority of cases, so that a proper treatment method could be introduced.

[Subacute epidural hematoma].
Eleven patients are reported who had subacute epidural haematoma diagnosed by CT 48 hours after craniocerebral trauma. These haematomas, most frequently, were located outside the temporal region. In some cases capsule of the haematoma could be recognized. The indication to surgical treatment was increasing intensity of intracranial pressure and development or persistence of the signs of focal CNS injury. Effective conservative treatment was given to patients with good general condition in whom CT showed no shifting of midline structures over 5 mm, and the fissure of the fracture was not lying transversely to the course of middle meningeal artery branches.

[Application of alteplase in prevention of cerebral vasospasm and its sequelae in patients after aneurysmal subarachnoid hemorrhage from ruptured cerebral aneurysm].
15 patients after SAH from ruptured cerebral aneurysm were operated on within 72 hours after SAH. During the operation after clipping of aneurysm 10 mg of rtPA was administered into basal cisterns, Control group consisted of patients who did not receive rtPA. All the patients on the basis of CT scan were classified to III grade according to Fisher's classification. Control CT scan revealed dissolution of most clots in basal cisterns. In comparison with control group the patients who received rtPA rarely experienced radiological signs of vasospasm and delayed neurological deficit.

[Aneurysm of the anterior communicating artery as a possible late complication of internal carotid artery ligation].
A case of a 55-year-old woman with anterior communicating artery aneurysm has been described. The aneurysm led to subarachnoid haemorrhage 8 years after ligation of the right internal carotid artery in order to turn off an aneurysm of this artery. Angiography showed the existence of collateral circulation through the arterial circle of the brain with haemodynamic disturbances, confirmed by Doppler ultrasonography. According to the views found in the literature these disturbances are considered the probable factor of initiation of the described aneurysm.

[A case of chondroma of the cerebello-pontine angle and clivus].
A 42-year old woman with a rare intracranial tumour-chondroma of the cerebello-pontine angle and clivus is presented. Clinical signs of the disease appeared when the tumour attained a huge size. Despite grave postoperative course the prognosis in our patient was good.

[Extramedullary erythropoiesis in cerebellar hemangioblastomas].
Three patients operated on for cerebellar haemangioblastoma are reported. Rarely observed extramedullary erythropoiesis was found in tumour tissue. One patient had erythrocytosis (solid form of the tumour), the remaining patients with cystic tumour had normal erythrocyte count.
