Recent findings using computerized tomography (CT) scans combined with autopsy observations have enhanced clinical interpretation of early inhalational anthrax evolution.
The earliest detectable specific finding pointing to inhalational anthrax is mediastinal widening on posteroanterior (PA) chest X-rays. However, mediastinal widening is not a rare finding in a series of patients presenting at a hospital emergency department. Imaging in inhalational anthrax patients using a non-contrast spiral CT will reveal hyperdense lymph nodes in the mediastinum associated with edema of mediastinal fat. The hyperdensity of the lymph nodes represents haemorrhage and necrosis, following spore germination and vegetative growth with exotoxin elaboration.
