[High resolution computed tomography findings in parainfluenza virus pneumonia after bone marrow transplantation: case report]. / Achados de tomografia computadorizada de alta resolução em pneumonia pelo vírus parainfluenza pós-transplante de medula óssea: relato de caso.

Nineteen year-old female patient, who underwent bone marrow transplantation because of chronic myelogenous leukemia, presented with dry cough and coriza sixty-seven days after the procedure. The chest radiograph was normal. The high resolution computed tomography showed a subsegmental air-space consolidation at the periphery of the left inferior lobe and areas of low attenuation at the superior and middle lung zones. The bronchoalveolar lavage demonstrated positive direct fluorescence antibody testing against parainfluenza virus. Treatment with aerolizated ribavirin was instituted during 10 days and the patient showed clinical-radiological improvement.
