Spontaneous Intracranial Hemorrhage Associated With an Intracranial Meningioma

Spontaneous intracranial hemorrhage associated with an intracranial meningioma is rare, with a reported incidence of below 2.4% of all meningiomas. Such cases are described with a cause subdural with intratumoral hemorrhage, which is a challenge for patients and healthcare professionals because it can occur spontaneously without other pathological antecedents. We describe the case of a 55-year-old woman with subdural hemorrhage over the frontoparietal region of the right hemisphere associated with a meningioma, generating a mass effect and shifting the third ventricle and lateral ventricle. Therefore, urgent surgical treatment was decided. A tumor lesion was found with apoplexy, soft consistency, and violaceous color with abundant vascularity in the lesion's center, suggesting a probable angiomatous meningioma. The histopathological evaluation confirmed meningothelial hemorrhagic meningioma grade I, according to the World Health Organization grading. This article discusses the causes, risk factors, diagnosis, and surgical treatment for hemorrhage associated with intracranial meningioma.
