55-year-old woman was admitted to our hospital for cough. Chest X-ray films showed a giant tumor shadow in right anterior pleural cavity. Pulmonary arteriography showed a feeding artery from the branch of right superior trunk. We diagnosed the tumor might be mesothelioma from visceral pleura with stalk. We operated the patient and the tumor was turned out to be mesothelioma pathologically. The patient had a postoperative re-expansion pulmonary edema and recovered in a week. She lives well without recurrence for 3 years 8 months.
