Sarcoidosis with secondary recurrent right-sided chylothorax and chylous ascites in a Caucasian male patient.

Sarcoidosis is a rare multisystem autoimmune disease characterized by the presence of non-caseating granulomas in involved organs. We report a novel case of a 61-year-old Caucasian male with sarcoidosis presenting with recurrent chylothorax and chylous ascites. Pleural and ascitic fluid analysis revealed high triglyceride levels, consistent with chylothorax and chylous ascites, respectively. Common etiologies of chylous fluid such as thoracic duct surgical trauma, malignancy and infection were all excluded. Sarcoidosis was confirmed by the presence of non-caseating granulomas on a mediastinal lymph node biopsy. Conservative treatment with low-fat diet, prednisone, octreotide and multiple thoracenteses failed to effectively resolve the chylothorax. Surgical interventions with pleurodesis and thoracic duct ligation were performed, leading to the complete resolution of the chylous effusion and ascites.
