| Popis: | A 3-year-old child presented with severe type-7 adenoviral pneumonia, after the resolution of diffuse pulmonary infiltrates of the pneumonia. Xenon-133 ventilation and Tc-99-m macroaggregated albumin (MAA) perfusion studies revealed a localized airflow obstruction and matched perfusion defect, and marked air trapping in the remaining lungs, and these abnormalities were not detected and not suspected even with CT. Thereafter, in a relatively short period, the child developed persistent bronchiectatic changes and pulmonary hyperinflation throughout the lungs. However, the scintigraphic findings were not significantly changed. This is the first description of radionuclide scintigraphic findings which clearly showed an irreversible long-term functional effect of adenoviral pneumonia. |
