Angioinvasive aspergillosis is the most common cause of this sign in the immunocompromised host (3, 4). We report the case of a patient with acute lymphoblastic leukemia who developed the air crescent sign as a result of Staphylococcus aureus lung infection.Case ReportA previously healthy 18-year-old man presented in August 1991 with a 3-month history of fatigue; in addition, during the 3 weeks before presentation, he experienced headache, bruising, and a 4.5-kg weight loss. Physical examination revealed widespread ecchymoses of the upper and lower extremities, generalized...References1. CurtisWalker SmithRavin HGC. Air crescent sign of invasive aspergillosis.
