[A case of paragonimiasis westermani].
A 45-year-old man, who had eaten fried fresh water crabs (Geothelphusa dehaani), was admitted to our hospital because of productive cough and bloodysputum. Blood chemistry showed increased levels of white blood cells and C-reactive protein, but peripheral blood eosinophil counts and serum IgE values were not elevated. Chest roentgenogram and chest computed tomographic scan revealed infiltration of the right middle and left upper lung fields. He was diagnosed as having pneumonia, but his symptoms and radiological examination findings did not improve with antibiotics. The diagnosis of paragonimiasis was confirmed by immunoserological examination and detection of ova in sputum, stool and bronchoalveolar lavage fluid samples. Transbronchial lung biopsy showed infiltration and degranulation of eosinophils. The patient was treated with praziquantel for 3 days at a daily dosage of 75 mg/kg. After uneventful completion of treatment all clinical symptoms and radiological abnormalities disappeared. This is the first case in which ova of paragonimiasis westermani were identified in Nagano prefecture.
