Spontaneous or Traumatic Intratumoral Hemorrhage? A Rare Presentation of Parafalcine Meningioma.

ABSTRACT

While hemorrhage is commonly encountered in various intracranial tumors, it is relatively rare in benign meningiomas. We present an interesting case report of a 75-year-old male who fell during intoxication, sustaining right frontal cranial trauma, coincidentally directly overlying a previously undiagnosed right frontal meningioma. He experienced an acute neurological decline and was found to have an intracranial hematoma, causing significant mass effect and herniation. Based on the radiographic appearance, an underlying neoplasm with significant edema was suspected. Intraoperatively, the hematoma and mass were successfully evacuated, and post-operative pathology confirmed the presence of a World Health Organization Grade I meningioma with a microcystic and angiomatous pattern. We speculate on the mechanism of injury and hemorrhage in this patient through review of the literature and discussion of medical and pathological risk factors.
