title: Case report: the air crescent sign in pulmonary leukaemic infiltrate.
abstract: Localized pulmonary infiltrates in leukaemic patients were until recently almost synonymous with superinfection. This case illustrates that true leukaemic pulmonary involvement should always be considered in these patients when a high peripheral blast count is present. We believe this to be the first description of cavitation in a proven leukaemic infiltrate.
