    Abstract:
    Paragonimiasis is a crustacean-borne parasitic zoonosis caused by lung fluke or Paragonimus. Several endemic foci of paragonimiasis have been discovered in Northeastern India. Chronic pulmonary infection with Paragonimus is characterized by hemoptysis, which is usually mistaken for Tuberculosis (TB). Paragonimiasis is acquired by eating raw, undercooked, or pickled crabs or crayfish containing encysted metacercariae of Paragonimus. Infection can usually be confirmed by finding Paragonimus eggs in sputum or bronchoalveolar lavage. We present a rare case of paragonimiasis masquerading as hypereosinophilia, asthma, and intracerebral hemorrhage for the last three years. Paragonimiasis is a rare cause of hemoptysis outside endemic regions. A strong index of suspicion is required to diagnose paragonimiasis outside the endemic areas. Diagnosis is usually delayed because of similarity of presentation to TB. Our patient was symptomatic with hemoptysis for three years. He gave history of eating raw crayfish and crabs while on leave to his native village in Nagaland. Diagnosis was confirmed on microscopy by detection of Paragonimus ova in sputum and bronchoalveolar lavage specimens. Symptoms resolved on treatment with praziquantel (25 mg/kg TDS for three days). Patient became symptom-free after a week of treatment.
