Plain-English summary
An 11-year-old male French bulldog was found to have cysts in his lungs during a CT scan, which were suspected to be linked to a parasitic infection called paragonimiasis. The dog had been exposed to brackish water and was likely eating crabs from the river, which can carry the parasites. The advanced imaging showed movement of live worms inside the cysts, helping to confirm the diagnosis. This case highlights how dynamic computed tomography can be useful in identifying this specific type of lung issue in dogs.

Abstract
An 11-year-old male French bulldog presented with incidental cystic lesions by the pulmonary CT. CT revealed two cysts in the right caudal lobe of the lung that were suspicious for emphysematous lesions. These cysts were divided into an air layer and a soft tissue-like layer. Dynamic computed tomography (DCT) of cysts revealed undulating motion in the soft tissue-like layer. The dog's rearing environment included brackish water, and it was evident that the dog had been eating brackish water crabs from the river. The dog was diagnosed with paragonimiasis. This DCT imaging revealed movement of live worms inside the cysts. This study is the first report that DCT may be useful for differentiating paragonimiasis from other pulmonary lesions.
