INTRODUCTION Primary intraosseous cavernous hemangiomas of the skull are very rare in the pediatric age group and usually slow-growing tumors. CASE REPORT We present a case of 5-month-old girl with a left occipital cavernous hemangioma that is rapidly growing. The subcutaneous occipital tiny mass was first noted at birth, and the lesion became rapidly enlarged in size and became soft for 3 months. The left occipital subcutaneous lesion was 4.0 × 4.0 × 2.0 cm (AP × LR × HT) in size. There was no history of trauma or bone tumor in her family. She underwent resection of the lesion, and a pathologic diagnosis of calvarial cavernous hemangioma was made. No recurrence was seen 1 year after surgery. CONCLUSION The rapid growth of the infant cavernous hemangioma might be related to not only bleeding and/or congestion of the lesion but the immature thin skull of the infant.
