Pituitary apoplexy: endocrine, surgical and oncological emergency. Incidence, clinical course and treatment with reference to 799 cases of pituitary adenomas.

Authors analyzed retrospectively the incidence of pituitary apoplexy in a series of 799 pituitary adenomas with respect to the long term follow-up of the patients. Focal vascular abnormalities in histological specimens of tumours, regarded as morphological suggestion of past apoplexy (haemorrhage, ischaemic infarction or necrosis), were established in 113 out of 783 surgical cases (14.4%).

[Teratoma of the posterior cranial fossa].

Two cases of posterior cranial fossa teratomas are reported. The rarity of these lesions is stressed. In the material of surgically treated cases of brain tumours from a period of 12 years in only two patients teratomas of this location were found.

[Many-year survival after surgical treatment of glioblastoma multiforme. Report of 2 cases].

Two female patients are described with survival over 13 years after operation for glioblastoma multiforme. The first patient was 42-year-old at the time of partial removal of the tumour situated in deep parts of the temporal lobe. After the operation she was not given any radiotherapy.

[Postoperative radiotherapy of glial tumors of the central nervous system].

The authors analysed the survival time of 372 patients subjected to radiotherapy after operations for central nervous system tumours of glial origin. Subtentorial gliomas with a better prognosis than supratentorial gliomas accounted for 82% of cases in this group of 67 children, and cerebellar medulloblastoma most sensitive to radiation accounted for 85%. In the group of 305 adults supratentorial tumours were found in 90.
