A rare form of sparganosis with eosinophilic pleural effusion is reported. A 62-year-old man was admitted to our hospital with left pleural effusion, and diagnosed immunologically as having sparganosis. Eosinophilia was seen in both peripheral blood and pleural effusion. The level of interleukin (IL)-5 was elevated in the pleural effusion, but not in peripheral blood. The patient was treated successfully with three consecutive doses of praziquantel (75 mg/kg/day). After the treatment, the antibody titer in serum decreased and the eosinophil number in the peripheral blood returned to the normal level. Thus, sparganosis should be included in the differential diagnosis for eosinophilic pleuritis. The immunoserological screening test using multiple-dot ELISA is helpful to identify the causative pathogen.
