In the pleural effusion of a 46-year-old man with pulmonary paragonimiasis, numerous floating particles containing parasitic ova and granulation tissue were observed. The floating particles appeared as diffuse hyperechoic foci in the anechoic pleural effusion on ultrasonography. We concluded that rupture of the intrapulmonary paragonimiasis lesion into the pleural cavity caused the formation of these floating particles.
