Abstract
Pulmonary hemangiomatosis is a rare disease of unknown etiology characterized by diffuse proliferating microvessels that infiltrate not only the lung but also all of the thoracic tissues. The disease is rapidly progressive and usually results in death due to complications of pulmonary hypertension and pulmonary hemorrhage. There are two histologic patterns of pulmonary hemangiomatosis : capillary and cavernous. We describe a 21-year-old man with cavernous-type pulmonary hemangiomatosis presented with right side shoulder pain. He was treated with percutaneous transarterial embolization and then followed with interferon alfa-2a for one year with favorable clinical and radiological response.
