title: Haemophilus influenzae abscess presenting as an asymptomatic lung mass.
abstract: We report the radiographic and computed tomographic findings in an asymptomatic patient who had a Haemophilus influenzae lung abscess. The diagnosis was made by Gram's staining and culture of abscess material obtained by transthoracic needle aspiration. The radiographic abnormalities cleared after specific antimicrobial therapy.
