title: Intratumoral haemorrhage: a clinical study.
abstract: Although the incidence of spontaneous intracranial haemorrhage associated with meningioma is 1.3%, the incidence of intratumoral haemorrhage could not be determined. The authors report on 11 patients, six men and five women, with meningiomas that presented as spontaneous intratumoral haemorrhage, among 126 meningioma cases which were evaluated radiologically and histopathologically. The average age of patients was 58.9 years (range 45-72 years). Two (1.5%) cases showed radiological, and nine cases (7.9%) showed microscopic bleeding. Most of these cases also showed microcysts (9.7%) and necrosis (6.3%). The location, histopathological types, sex, age, blood dyscrasia, hypertension do not influence the occurrence of intratumoral haemorrhages in meningiomas. We concluded that microcysts and necrosis are important in the occurrence of intratumoral haemorrhage in meningiomas.
