A 76-year-old male developed a hemorrhagic nodule and a surrounding purple-red, irregularly shaped macule on his scalp after head trauma. The diagnosis of angiosarcoma was confirmed histologically. A transarterial feeder embolization was performed followed by a surgical excision. It was effective for bleeding from a tumor, and superselective catheterization was important for this specific tumor. The early diagnosis by neurosurgeon may lead to improved survival.
