title: Radiological findings in pulmonary paragonimiasis heterotremus.
abstract: The routine chest roentgenogram of pulmonary paragonimiasis heterotremus were evaluated in 93 Thai and Laotian patients. They were 44 males and 49 females; the ages ranged from 12 to 79 years; the history of illness ranged from 4 months to 14 years and the egg output per day was 400 to 300,000. Twelve patients, 12.9% had normal roentgenologic films and 81 patients (87.1%) had abnormalities with 316 lesions; 22.2% had one lesion and 77.7% had multiple lesions. The common lesions were cystic formation, multiple or single and linear infiltration. Both lower lobes of the lungs and the left upper lobe were the common sites but any part of the lung may be affected. There were correlation between the duration of illness, number of eggs output per day and the extent of the lesions. The longer the duration of illness or the higher number of eggs output per day the more extensive lesions in the X-ray films have been observed.
