Abstract
Infection caused by the lung fluke is endemic in north eastern parts of India. Paragonimus westermani and Paragonimus heterotremus are known to be endemic in eastern Indian states of Manipur and Nagaland. The infection is related to eating habits of the locals and is acquired by ingestion of raw, inadequately cooked crabs or crayfish containing encysted metacercariae which act as second intermediate hosts during the life cycle of the lung fluke. Diagnosis is generally delayed due to lack of suspicion and presentation similar to tuberculosis which is endemic in the population. We report pleuropulmonary paragonimiasis in a soldier from eastern India who presented with chest pain, haemoptysis, and eosinophilia. He gave history of consumption of raw crabs while on leave at his native village in Nagaland. Ova morphologically resembling Paragonimus heterotremus were detected in sputum and bronchoalveolar lavage specimen. Symptoms resolved with praziquantel treatment.
