Sparganosis is a parasitic infection caused by the metacestode stage of Spirometra mansoni and some other related diphyllobothriidean cestodes. Although various internal organs were involved in sparganum infection, pulmonary and pleural involvement is rarely reported. We herein report an uncommon form of sparganosis manifested by pleuritis and decreased peripheral blood eosinophils. Sparganum worms were found in the pleural effusion accidentally and confirmed by pathological diagnosis. After being treated with praziquantel for 10 days, the patient’s symptoms, laboratory examinations, and imaging findings were improved gradually.
