title: [Spontaneous hemorrhage in brain tumors].
abstract: In a period of 15 months in a material of 235 surgically verified brain tumours in 8 cases (3.4%) hemorrhages into the tumour mass were found. In 3 of these cases the tumours were anaplastic astrocytomas, the remaining tumours were: oligodendroglioma, meningioma, pituitary adenoma and metastases of renal carcinoma and skin melanoma. The clinical manifestations associated with haemorrhage are discussed stressing that haemorrhage into the tumour worsened the prognosis.
