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.
