Abstract
Chylothorax is an infrequent cause of pleural effusion that is most commonly caused by the obstruction or disruption of the thoracic duct. Chylothorax is rare in nephrotic syndrome. Unilateral chylothorax of the right side is due to the transdiaphragmatic shunting of chylous ascites. It is usually transient and self-limiting but a massive chylothorax requiring therapeutic thoracentesis can also be encountered. Here, we present a rare cause of chylous ascites-nephrotic syndrome resulting in chylothorax, where initially therapeutic thoracentesis is done followed by the management of nephrotic syndrome with modified Ponticelli regimen. This case highlights the need to consider chylous ascites as a cause of chylothorax via transdiaphragmatic shunting in patients with nephrotic syndrome to institute the appropriate treatment.
