Chylothorax caused by Paragonimus westermani in a native Californian.

Abstract

Paragonimiasis is a parasitic infection endemic in Asia but uncommon in the United States. It presents most frequently with cough and hemoptysis. Pleural effusions are common and can manifest occasionally as a pseudochylothorax, but a true chylothorax has, to our knowledge, never been reported. We report a case of a chylothorax from infection with Paragonimus westermani. The case is also unique because it occurred in a native Californian who had not traveled to Asia and was infected by eating raw crabs at a local sushi restaurant. The freshwater crabs had been imported from Asia.
