Abstract

Paragonimiasis mostly occurs by ingestion of raw or undercooked freshwater crabs or crayfish. Recently, re-emergence of paragonimiasis is reported because of ingestion of raw food such as freshwater fish and Gejang (marinated raw crabs). As the radiological features as well as the laboratory findings are similar to those of chronic eosinophilic pneumonia, the diagnosis of pulmonary paragonimiasis is often difficult and delayed. A 43 year-old female was visited our hospital for migrating and new developing consolidative lung lesions and peripheral blood eosinophilia. The eosinophil profile of leukocyte was 32% (absolute count 2,690 /mm3). Histologic finding was organizing pneumonia pattern with severe infiltration of eosinophils. Parasite specific antibody IgG forParagonimus westermani was positive (titer:0.61, normal range<0.20). After treatment with praziquantel (75mg/Kg once a day for 2days), the chest x-ray was clearly resolved. Follow-up study showed right pleural effusion, newly developed focal infiltration, and several nodules. After retreatment, we couldn't find any recurrent evidence.
