A previously healthy 7-year-old boy was admitted to the hospital with 1 week of temperatures up to 40.2 °C (104.4 °F), productive cough, and lethargy, which did not improve after 3 days of oral cefuroxime. He lived in rural China and had close contact with dogs, cattle, and sheep. His blood pressure was 93/60 mm Hg; heart rate, 100/min; respiratory rate, 26/min; and oxygen saturation, 94% on room air. Lung auscultation revealed absent breath sounds on the right hemithorax. His abdomen was soft and nontender, without hepatosplenomegaly. His white blood cell count was 8000/?L, with 25.8% eosinophils (reference range, 0%-9%). C-reactive protein level and results from tuberculin skin test, interferon-? release assay, nucleic acid amplification testing for tuberculosis, acid-fast bacilli smear microscopy, and HIV antibody testing were normal. A thoracoabdominal computed tomography (CT) scan showed a ruptured 10?×-9?×-5–cm right upper lobe pulmonary cyst compressing the right main bronchus and 3 liver cysts ().
