ABSTRACT
Scalp arteriovenous malformations are treated by surgical excision in many patients. We report a patient with a scalp arteriovenous malformation who was successfully treated by a combination of ultrasound-guided thrombin injection (UGTI) and transarterial coil embolization. This patient was a 52-year-old man with a subcutaneous mass in the left retroauricular region. An angiogram showed that the mass was a nidus of arteriovenous malformation. We performed UGTI after transarterial coil embolization. No recurrence or complication was reported during 2 years of follow-up. This report describes the advantages of UGTI and the method for complete occlusion of the collateral artery.

A case of adult teratoma with malignant transformation in a 52-year-old male is reported. We describe characteristic CT, histopathologic features and histogenesis of the tumor. Gradual onset of cerebral signs and symptoms was considered to be due to the tumor originating from the silent area of the frontal lobe of the brain and possessing a slowly progressive growth character.
