Ⅰ．はじめに

　1845年Toynbee^20）により最初に報告された頭蓋骨血管腫は，全骨腫瘍の0.2％を占めるにすぎず^21）稀な疾患であり，本邦においては未だ詳細な報告はほとんどみられていない．

　このたびわれわれは，それぞれ左頭頂骨および右前頭骨に発生した頭蓋骨血管腫の2例を経験したので，これらを提示し，あわせて若干の考察を加えて報告する．

Two cases of hemangioma of the skull were presented in this paper.

Case 1. A 63-year-old man was admitted to our hospital because of a complaint of a small firm elevated area of the left parietal region. Physical examinations were normal except for this lump. The laboratory findings were normal and no neurological deficits were found. Plain skull films showed a 3×3cm honeycombed lucent defect in the left parietal bone and sunray appearance in tangential views. The vascular rich tumor, which contrasted sharply with the surrounding bone, was removed en block. Postoperative course was uneventful.
