Overview

On x ray of affected area, necrotizing fasciitis is characterized by subcutaneous gas or soft tissue swelling (specific x-ray finding) and increased soft tissue thickness and opacity. Chest x-ray findings associated with necrotizing fasciitis include early changes of fluid overload and adult (acute) respiratory distress syndrome (ARDS).

X Ray

X ray of affected area

• On X-ray, necrotizing fasciitis is characterized by:

• Subcutaneous gas or soft tissue swelling (specific x-ray finding)
• Increased soft tissue thickness and opacity

• Plain x-ray is a poor screening study for necrotizing fasciitis because:

• Subcutaneous emphysema is an insensitive finding and is present in a minority of patients
• In the early stages the findings are similar to cellulitis

Chest X Ray

• Chest x ray findings are associated with necrotizing fasciitis include:

• Early changes of fluid overload
• Changes of adult (acute) respiratory distress syndrome (ARDS).
