This study presents six patients with hypothalamic hamartomas diagnosed on the basis of magnetic resonance imaging. Histological confirmation was performed in three patients who underwent surgery. Immunohistological assays were used to determine the neurosecretory pattern. Four patients presented with epilepsy, including gelastic seizures. Other symptoms(More)
The results of transnasal-transsphenoidal surgery in 31 patients with craniopharyngioma are evaluated. To assess the value of transnasal surgery in cases with visual impairment, the results are compared to cases operated transcranially. There was only one death occurred on the 5th postoperative day. Two patients developed rhinoliquorrhoea, and one a(More)
We are reporting the functional outcome of 69 of 86 patients affected by intramedullary spinal cord tumors who underwent surgery at our department during the period of 1984 to 1992. The results on 17 patients affected by hemangioblastomas and cavernomas were excluded from this study and will be published separately. Twenty-eight patients had astrocytic(More)
The contents of 14 cysts that were located within human intracranial tumors were obtained at surgery by needle aspiration. These tumor cyst fluids (TCFs) were mostly derived from glial tumors (10 cases). TCFs from one metastasis from a mammary carcinoma, one cystic meningioma, one hemangioblastoma, and a cystic acoustic neurinoma were also included. These(More)
Most of the previously published surgical series of suprasellar meningiomas have two disadvantages: (1) patients involved were treated within a relatively long time period, making analysis more difficult, (2) radiographic long term follow-up examinations with either CT- or MRI-scans were not performed. Both disadvantages were overcome in our retrospective(More)
In 1981 we reported about a new surgical procedure for the treatment of spasmodic torticollis (ST). 33 patients, who failed to respond to the available conservative treatment, underwent a bilateral microsurgical lysis (BML) of the spinal accessory nerve roots (SRAN). Anastomoses between SRAN and the dorsal roots of the first and second cervical nerve (DRC(More)
The evaluation of tumours located in the posterior part of the third ventricle or pineal region is achieved best by magnet resonance imaging (MRI). It shows the exact localization and extent, the involvement of neighbouring structures like thalamus or quadrigeminal plate and the displacement of the large veins, the internal cerebral veins, the vein of Galen(More)
The immunocytochemical staining patterns of cultured glioma cells were investigated. Fifty nine individual cases were stained at different in vitro ages for glial fibrillary acidic protein, fibronectin, galactocerebroside, HNK-1/Leu 7, A2B5, vimentin, factor VIII and A4. Histologically, the cases were composed of eight low-grade astrocytomas, 11 high-grade(More)
Four cases are presented, in whom cerebellar haemorrhages appeared as a complication following supratentorial craniotomy for a giant aneurysm, for tumours in three cases. Two patients died. Intracranial hypotension in combination with disturbed blood coagulation is discussed as possible pathogenesis. Because this seems to be a rare complication--similar(More)
Systematic review of the cerebral angiograms of 446 head trauma patients (1971-1978) revealed the presence of an arteriovenous (AV) fistula of the middle meningeal artery (MMA) in 8 cases (1.8%), the total number of angiographically demonstrable injuries of the MMA being 18 (4%). AV fistulae of the MMA may prevent formation of epidural haematoma, but they(More)
