Fig. 2. 38-year-old woman with acute myelogenous leukemia visited our institution for aggravated fever, cough, sputum, and dyspnea for four days.

A. Chest radiograph at admission demonstrates subtle focal opacity in right upper lung zone (white arrow). B, C. Chest CT scans obtained on same day demonstrate patchy peribronchial ground-glass opacity in both lungs (black arrows). Total CT score was 3. Culture and RT-PCR of BAL fluid confirmed adenovirus pneumonia. D. Follow-up chest radiograph obtained after two weeks of treatment with cidofovir demonstrates disappearance of focal opacity in right upper lung zone, suggesting type 1 disease pattern. BAL = bronchoalveolar lavage, CT = computed tomography, RT-PCR = reverse transcription polymerase chain reaction
