Meningiomas are the most common benign intracranial tumors and make up 13-26% of all primary intracranial tumors. Clinical presentation of hemorrhage is rare in these tumors occurring in approximately 1.3% of cases and subdural hemorrhages are even more uncommon. The mechanism of hemorrhage is still unclear and may vary according to histologic type, location and the type of hemorrhage. We experienced a case of 61-year-old woman with a benign meningioma presenting as a subdural hemorrhage. She developed sudden onset of headache right after aggressively coughing. Her headache persisted for a week before she was admitted to the emergency room of National Cancer Center. She had a past medical history of ovarian cancer which had been treated and was allegedly recurrence-free for 2 years. At the time of admission, a headache was the only symptom and imaging studies showed a right frontal hemorrhagic subdural mass lesion accompanying an ipsilateral subdural hematoma. Elective surgery was performed and intraoperative findings revealed the hallmark characteristics of a meningioma with mixed stage diffuse subdural hematoma. Permanent pathology result determined it was a conventional meningioma (World Health Organization grade I). From this case, we discuss the rare presentation of subdural hemorrhage in meningioma and related points by reviewing the literature of previous studies.
