Role of Lymphatic Embolization in Chylothorax Associated with Gorham-Stout Disease: A Case Report.

A 45-year-old male patient with spontaneous chylothorax and osteolysis in the right 1st and 2nd ribs was diagnosed with Gorham-Stout disease based on clinical manifestations and bone biopsy. The chylothorax temporarily decreased after a successful selective lymphatic embolization. The patient presented with recurrent chylothorax, mild chest discomfort, and progressive osteolysis (despite administering sirolimus) during the follow-up period of 15 months.
