Abstract:
A 65-year-old woman with a known right-sided, dural-based lesion and metastatic pancreatic neuroendocrine tumor presented with multiple days of progressive lethargy and left-sided weakness culminating with obtundation and dilated pupils. Computed tomography demonstrated an acute right convexity subdural hematoma and a frontotemporal intraparenchymal hemorrhage with 1.3 cm of midline shift, uncal herniation, and an increase in size of now a hemorrhagic dural-based lesion. She underwent emergency hemicraniectomy for evacuation of subdural hematoma and resection of hemorrhagic meningioma with excellent postoperative result including improvement in midline shift and gross total resection of lesion. Pathology was consistent with a World Health Organization grade II meningioma with a chordoid component. She underwent adjuvant stereotactic radiosurgery and cranioplasty and made a full neurologic recovery. Identification of hemorrhagic meningioma as the underlying pathology causing multicompartmental hemorrhage is crucial. We recommend single-stage decompression with extraaxial clot evacuation and resection of the meningioma when feasible.
