Vein of Galen Malformation

A 59-year-old man presented with sudden onset of headache, nausea, and vomiting. He denied any significant medical illness and history of head injury. On arrival, his consciousness was clear and no neurologic deficit was found. Computed tomography of the brain showed intraventricular hemorrhage with hydrocephalus, and subarachnoid hemorrhage. Further computed tomography angiography showed the presence of a large arteriovenous malformation involving bilateral temporal horns, medial temporal regions, along the posteroinferior falx region, which indicated the diagnosis of vein of Galen malformation (Figure 1A and B, arrows).
