Abstract
Pulmonary infiltration and pleural effusion caused by permeability syndrome are the hallmark of pulmonary manifestation of dengue cases. We report a 95-year-old chronic obstructive pulmonary disease case having dengue shock syndrome. Chest X-ray examination revealed diffuse lung infiltration. However, bilateral pneumotoceles were unexpectedly found in computed tomography (CT) images. Dengue virus type 2 infection was confirmed by virus culture, serology and reverse transcriptase-polymerase chain reaction. Profound shock with bilateral lung infiltration developed rapidly in 2 days with supportive care and empirical ampicillin/ sulbactam. Bronchoscopy revealed a whitish plaque over bilateral upper bronchi. Biopsy via bronchoscopy revealed moulds with vascular invasion. Culture of bronchial alveolar lavage yielded Aspergillus flavus. The patient died despite amphotericin B treatment, which was started since finding the whitish plaque with bronchoscopy examination. Besides to considering capillary leakage syndrome, our case report and literature review alert clinicians that CT and bronchoscopy may help to identify the true pathogen though all cases with concurrent dengue and Aspergillus infections had fatal outcomes.
