Necrotizing fasciitis - WikEM Low risk — <50% probability of necrotizing fasciitis Consider other diagnoses but maintain clinical suspicion Moderate risk — 50–75% probability Consider surgical consultation and advanced imaging High risk — >75% probability of necrotizing fasciitis Urgent surgical consultation for exploration Wong CH, Khin LW, Heng KS, et al
Skin and soft tissue infections (including necrotizing fasciitis) Occasionally, a CT scan can be diagnostic (e g , gas in tissues or thickened, nonenhancing fascia) When CT isn't diagnostic, it may nonetheless help direct the surgeon to the best region to explore
Necrotizing Fasciitis and Its Mimics: What Radiologists Need to Know - AJR Necrotizing fasciitis is a rapidly progressive often fatal soft-tissue infection most commonly resulting from polymicrobial infection The process initially begins in the superficial fascial planes and progresses into the deep fascial layers causing necrosis by microvascular occlusion
Necrotizing soft tissue infections - UpToDate Necrotizing soft tissue infections (NSTIs) include necrotizing forms of fasciitis, myositis, and cellulitis [1-4] These infections are characterized clinically by fulminant tissue destruction, systemic signs of toxicity, and high mortality

Should a CT scan be performed with or without contrast to diagnose . . . CT with intravenous contrast is the preferred imaging modality for diagnosing necrotizing fasciitis as it allows visualization of both fascial thickening and lack of fascial enhancement, which are highly specific findings for necrotizing fasciitis 1
