Acute eosinophilic pneumonia masquerading as multiple pulmonary embolisms.

A 47-year-old previously healthy man was admitted to the hospital with a 5-day history of fever, dry cough, and dyspnoea. Thoracic radiographs and CT scan showed extensive bilateral consolidation predominantly involving the central portions of the upper lung lobes, along with multiple scattered nodules. On taking a thorough history, it was found that the patient had visited a gritty 100-year-old Japanese folk house 1 week ago. An urgent bronchoscopy was performed, and the results were consistent with the findings of acute eosinophilic pneumonia (AEP). The patient's respiratory distress resolved within 10 days without treatment. Hence, even in an AEP case with atypical radiological presentations, careful history taking can lead to a rapid diagnosis.
