Abstract:
The CT findings of pulmonary paragonimiasis are well known. However, the pathologic findings of nodular opacity have not been studied sufficiently. To clarify the nature of nodular opacity on CT in patient with paragominiasis, we reviewed CT scans of 9 patients retrospectively. Five of them were compared with pathologic findings of the resected specimen. Other four patients were confirmed by needle aspiration biopsy. CT scans showed nodular opacities of 5 to 30mm in diameter which were accompanied with perinodular air-space consolidations in all patients. The usual location of nodular opacities were peripheral zone of the lung. Correlation with pathologic findings demonstrated That the nodular opacity on CT scans corresponded to the parasitic granuloma with central ova and intracystic worm. The most frequent CT finding of pulmonary paragonimiasis was nodular opacities with perinodular airspace consolidations caused by parasitic granuloma or intracystic worm.
