Traumatic arteriovenous malformation of scalp: A case report

Scalp arteriovenous malformation (SAVM) as a rare lesion may be a complication of head injury. A case and its management are presented in this article and literature is reviewed. A 27-year-old man came to us with a slowly growing pulsatile mass in his right retroauricular and parietal region of the scalp. On examination, there was a compressible mass with loud bruit. Paraclinical studies revealed a large, tortuous tuft of vessels with two different feeders. Intracranial vessels were 3 normal. The lesion excised totally by direct surgical intervention after ligation of its feeders. The patient recovered and discharged without any abnormal findings. Increased number of reports of SAVM in the past decade may be due to improved diagnostic facilities; however, the high incidence of trauma and even its increasing pattern in developing countries may be another important factor.
