Dynamic Contrast-Enhanced Magnetic Resonance Lymphangiography and Percutaneous Lymphatic Embolization for the Diagnosis and Treatment of Recurrent Chyloptysis.

Chyloptysis, or the expectoration of triglyceride-rich sputum, is rare and typically treated with diet modification and thoracic duct ligation. This article describes 2 patients with prolonged histories of chyloptysis who failed conservative treatment and thoracic duct ligation. Dynamic contrast-enhanced magnetic resonance imaging delineated the lymphatic anatomy and identified the abnormal pulmonary lymphatic perfusion pathways in both patients. This imaging provided guidance for successful percutaneous lymphatic embolization which resulted in resolution of symptoms in both patients.
