CTICasesHyperthermia-Induced Cardiac Arrest with Ice Pack Artifacts
Imaging findings
Frontal portable chest radiograph demonstrates diffuse, bilateral, blotchy, and high-density material overlying the chest wall and upper extremities, representing therapeutic ice chips packed around the patient.
Key takeaways
Severe hyperthermia during heat waves is a critical emergency, particularly in elderly populations. Emergent cooling techniques, such as packing the patient in ice, can create prominent, high-density overlying artifacts on portable radiographs that should be recognized as external therapeutic materials rather than intrathoracic abnormalities.
