A case of asymptomatic paragonimiasis with mobile pulmonary lesions and concomitant liver fluke infection.

We report here an asymptomatic patient showing the location of lung lesions that differ between the first and subsequent chest CT scans. This raised suspicion of paragonimiasis, which ultimately led to its diagnosis. For physicians with limited or no experience with paragonimiasis, the observation that the location of lung lesions differs over time on imaging tests is an important clue in suspecting paragonimiasis. Moreover, this patient was co-infected with liver fluke. Even when one kind of parasitic infection is identified, it is important to be aware of other parasitic infections.
