A 49-year-old male was admitted because of an abnormal nodule on chest CT taken during examination for chest oppression and a solitary nodular arteriovenous fistula was identified in the right S6 by high resolution CT. Surgical resection was indicated because of single lesion and of history of embolism such as acute myocardial infarction and himilateral myopia. Under an ultrasonic guidance, the lesion was successfully identified and resected with a minimal margin using a harmonic scalpel. The patient recovered uneventfully and was discharged on the 7th postoperative day.
