Use of Infrared Thermography in Diagnosing Necrotizing Fasciitis in the Emergency Department: A Case Study

Objective: Necrotizing fasciitis is a difficult diagnosis with a very high mortality. However, thermal imaging has the potential to identify increasing skin temperature and rapid progression. Materials and methods: We used repeat photographs taken with a thermal camera to visualize changes in skin temperature over time. Results: An unstable male patient presented at the emergency department. Thermal imaging showed increased skin temperature of his left foot with a rapid increase and progression in extent within 1 hour. Necrotizing fasciitis was suspected and later confirmed. Conclusions: We believe thermal imaging could be an important adjunct for the diagnosis of suspected necrotizing fasciitis
