ABSTRACT
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.

We report a case of fatal anaphylactoid shock caused by a CT examination using nonionic contrast medium. A 79-year-old female patient was diagnosed with right recurrent nerve plasy. There was no known history of drug allergy or exposure to contrast medium. Approximately 50 seconds after contrast medium bolus injection began, the patient was noted to be apneic. Despite cardiopulmonary resucitation, the patient died. An autopsy demonstrated marked laryngeal edema and showed extensive mast cell infiltration.
