Paragonimiasis has been continuously decreasing in Korea. However, it still occurs by ingesting raw or incompletely cooked fresh water crab or crayfish. The diagnosis of paragonimiasis is challenging because of its rarity. It may be confused with other inflammatory disease or carcinomatosis. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has lower risk of complications such as bleeding, perforation than percutaneous fine needle aspiration. EUS-FNA is more accurate and popular method to find mucosal or submucosal tumors and the lesions of several organs. Benign and malignant tumors, infectious diseases have been diagnosed by EUS-FNA, but there was no report describing the use of EUS-FNA for diagnosing paragonimiasis. Herein, we present a 47-year-old male patient with paragonimiasis diagnosed by EUS-FNA. Imaging studies revealed mass lesions in the lung and peritoneal cavity, which was eventually confirmed as paragonimiasis using EUS-FNA.
