High-resolution computed tomography findings of P. westermani.
Paragonimiasis westermani, or Oriental lung fluke, is a common parasitic zoonosis, which is acquired from eating the flesh of wild boar or freshwater crabs. After being ingested by humans, the larvae of P. westermani migrate across small intestinal mucosa into the intra-abdominal space, and then finally into to the pleural space and lung parenchyma. High-resolution CT findings of P. westermani consist of worm cysts, migration track, peripheral density, bronchial wall thickening, and centrilobular nodules, which prompt serological tests and detection of eggs in sputum or BAL fluid for definitive diagnosis.
