    Anthrax (Inhalational)

    Inhalational anthrax initially causes flu-like symptoms, which progress to high fevers and severe respiratory distress. Typical findings on chest x-ray include a widened mediastinum caused by hemorrhagic necrotizing mediastinal lymphadenitis and bilateral pleural effusions. Pneumonic infiltrates are uncommon.
