LYMPHANGIOHEMANGIOMA OF THE MEDIASTINUM

Lymphangiohemangiomas of the mediastinum are exceedingly rare. Clinica lly they tend to behave Hike lymphangiomas. We report 3 new cases. All 3 cases showed both lymphatic and vascular components. One case was a ssociated with a left superior vena cava. Hn both other cases computed tomography with dynamic scans demonstrated the vascular components. C ombined lymphatic venous malformation was thus evidenced in the 3 case s and supports that lymphangiohemangiomas are malformative in origin. (C) 1997 by The Society of Thoracic Surgeons.
