Abstract

The human metapneumovirus virus (hMPV) is a recently described human respiratory pathogen. The virus has usually been associated with upper and lower respiratory tract infections in children. Since most of the available data on the clinical manifestations come from observational studies on children, relatively little is known of emerging hMPV infections in the adult population in Korea. A 32-year old female patient, presenting fever, chills, cough and sputum for 3 days progressed to severe pneumonia during the season of pandemic influenza A/H1N1-2009. RT-PCR screening of viral pathogens revealed hMPV. Clinical improvement was achieved a week after illness. This case represents severe hMPV pneumonia developed in an immunocompetent adult.

  Figure 1 Chest radiograph of patient at admission and 4th day of admission. (A) The initial chest radiograph shows increased opacity in right mid to lower lung field. (B) After 4 days, the chest radiograph shows diffuse increased opacity in both lungs.

• 

  Figure 2 Chest computed tomography scan of the patient showed consolidations with ground glass attenuation in both lobes.

• 

  Figure 3 The radiologic findings of the patient with hMPV pneumonia were markedly improved during admission. (A) On the 7th hospital day, the chest radiograph showed gradually developing diffuse increased opacity in both lung. (B) On the 11th hospital day, there is no active lesion in both lung fields.
