[Paragonimiasis Miyazakii with variable X-ray shadows].

A 77-year-old woman was admitted to our hospital with hemoptysis and weight loss. She had eaten 15 raw freshwater crabs about 5 months before the onset of her clinical symptoms. Chest X-ray films obtained on the first admission showed left pleural effusion. After 1 week of chemotherapy with SBTPC, the pleural effusion disappeared. Two months later, the patient was re-admitted with recurrent hemoptysis. Chest X-ray films showed a solitary nodular lesion in the right lung. Eosinophilia and increased serum IgE levels were detected. The solitary nodular lesion moved from the middle to upper field of the right lung during the patient's 3-week stay in the hospital. Serologic tests yielded a conclusive diagnosis of Paragonimiasis miyazakii infection. Praziquantel administration relieved the patient's symptoms.
