Overview

Chest X-ray is a sensitive diagnostic test for inhalation anthrax. Chest X-ray abnormalities associated with inhalation anthrax include mediastinal widening, paratracheal fullness, pleural effusions, parenchymal infiltrates, and mediastinal lymphadenopathy.

Chest X Ray

  • The earliest detectable specific finding indicative of inhalational anthrax is mediastinal widening on posteroanterior chest X-rays. However, mediastinal widening is common in patients presenting at the emergency department.[1]
