Abstract:
Objective To explore the characteristics of chest multi-slice spiral CT and dynamic changes in adult patients with se-vere adenovirus pneumonia.Methods Clinical and CT data of 6 patients with severe pneumonia in an epidemic of the respiratory ade-novirus infection were retrospectively analyzed.The impact of hormone therapy was also studied.Results The first chest CT exami-nations in 6 patients were performed 2.22 ± 0.75 days after fever.CT showed segmental consolidation with ground-glass opacity (GGO)in one case,patchy consolidation with GGO in 3 cases,patchy interstitial changes in one case and small nodules in one case. The duration reaching the standards of severe pneumonia was 6.1 7 ± 0.37 days from the onset.During severe phase chest CT showed a range of lobar consolidation in one case,lobar in 2 cases,segmental in 2 cases or patchy in one case,consolidation with GGO in 5 cases.In all cases the lesions were commonly seen in the lower lobes of bilateral lungs.Multiple lobes were involved in 2 cases.After methylprednisolone treatment,no new lesion was showed but the early lesion was enlarged.During the first 2 to 4 days GGO absorbed completely in 6 cases,consolidation absorbed completely in one case and mostly in 5 cases.Conclusion Chest CT findings of severe adenovirus pneumonia in adult are single or multiple lobar or segmental consolidations with or without GGO which distribute mainly at lower lobes.
