Chylotamponade: an unusual presentation of Gorham's syndrome.

Gorham's Syndrome, also known as massive osteolysis or "vanishing bone disease" results from lymphangiomatosis with adjacent bone resorption. Chylothorax is a common complication in cases of mediastinal involvement. We report a case of Gorham's Syndrome presenting as chylotamponade successfully treated with pericardial drainage, early parenteral nutritional support, bilateral pleurodesis for chylous effusions, and adjuvant external beam radiation.
