Abstract：To investigate the CT appearances in early stage of clustering lung paragonimiasis, 9 cases of two clustering lung paragonimiasis caused by eating raw stone-crab and laboratory examination were included in the study. Eight cases consulted by doctors in the hospital and their appearances were retrospectively analyzed. There were pleural effusion of varying degree (n=8) and random distribution sub-pleural pulmonary infiltrative lesions (n=7). The accompany appearances of the latter had lunar halo sign, characteristic tunnel sign (n=1) and peri-bronchitis (n=1). If CT detects pulmonary infiltrative lesions of random distribution within sub-pleura or tunnel sign, combining with the history of eating raw stone crabs and other freshwater fishes, with the rise of eosinophilic granulocytes in peripheral blood, the diagnosis of paragonimiasis should be suggested.
