Non traumatic subdural hematomas are rare, especially those associated with intracranial meningiomas. Among the most common meningiomas associated with spontaneous bleeding are angioblastic and malignant meningioma variants. The pathophysiological mechanisms of this association are not yet fully understood. The association of chronic subdural hematoma with microcystic meningioma histological subtype has not yet been described in the literature. The authors present a case report of a patient with a spontaneous non traumatic chronic subdural hematoma associated with a microcystic subtype grade I meningioma of the parietal convexity. Epidemiological, etiology, natural history, pathophysiology, risk factors of bleeding and treatment options are reviewed. Spontaneous subdural hematomas associated with meningiomas are rare, specially related to the microcystic variant of meningioma. Careful pre-operative consideration of specific anatomy and pathophysiological features are paramount to their full treatment.
非创伤性硬膜下血肿很少见，尤其是与颅内脑膜瘤相关的血肿。与自发性出血相关的最常见脑膜瘤类型包括血管母细胞型和恶性脑膜瘤变种。这种关联的病理生理机制尚未完全明确。慢性硬膜下血肿与微囊性脑膜瘤组织学亚型的关联在文献中尚未见报道。作者报告了1例顶叶凸面自发性非创伤性慢性硬膜下血肿合并I级微囊性脑膜瘤患者的病例。本文回顾了其流行病学、病因、自然史、病理生理学、出血危险因素及治疗选择。与脑膜瘤相关的自发性硬膜下血肿很少见，尤其是与脑膜瘤的微囊性变种相关者。术前仔细考虑特定的解剖结构和病理生理特征对其全面治疗至关重要。
