title: Adenovirus pneumonia in an immunocompetent adult.
abstract: Adenovirus pneumonias are reported relatively commonly in pediatric or immunocompromised patients, but the clinical presentation of adenovirus pneumonia in immunocompetent hosts is not well known. We treated an immunocompetent 42-year-old man with mild adenovirus pneumonia following pharyngitis and conjunctivitis. Diagnosis was established on the basis of chest radiologic findings, detection of adenovirus type 7 DNA by PCR assay in material obtained from bronchoalveolar lavage (BAL), and a greater than fourfold rise in adenovirus-specific antibody titers during the course of illness. The patient's self-limiting symptoms improved within 2 weeks, and chest radiologic findings improved within 4 weeks. PCR assay of material obtained by BAL was useful for the rapid diagnosis of adenovirus pneumonia.
