Radiological changes in inhalation anthrax a report of radiological and pathological correlation in two cases

The radiological changes in two cases of inhalation anthrax are correlated with pathological findings. The earliest radiological sign was widening of the mediastinum, followed by prominent lung markings with peribronchial infiltration due to pulmonary oedema and haemorrhage. Associated pleural effusions are common, and non-specific super-imposed pulmonary infiltration may also be present. Inhalation anthrax must be considered in any case of mediastinal widening in a patient coming in contact with imported animal products or with livestock in endemic areas.
