BackgroundPrimary angiosarcoma of the brain is an extremely rare malignant tumor that that arises from vascular endothelial cells of the brain or meninges. The presentation, characteristics, and prognosis of this disease are not well understood. Here we report such a case.Case DescriptionA 68-year-old Chinese man presented with confusion and progressive impairment of right limb movement. Magnetic resonance imaging (MRI) revealed a hemorrhagic lesion in the left frontal lobe. Exploratory surgery revealed a hematoma-like lesion and extensive superficial hemosiderin deposition. The postoperative pathological diagnosis was angiosarcoma. The tumor recurred at 1 month after the operation, with extensive tumor regrowth in the left hemisphere. The patient died after 4 weeks.ConclusionsAlthough accurate preoperative diagnosis of angiosarcoma of the brain is difficult, radiologists and neurosurgeons need to be aware of this rare entity. The prognosis of intracranial angiosarcoma is heterogenous. Intraoperatively, the presence of extensive superficial hemosiderosis may aid in its diagnosis.Copyright © 2019 Elsevier Inc.
