Magnetic Resonance Imaging in the Early Diagnosis of Group A β Streptococcal Necrotizing Fasciitis: A Case Report

Modern Concepts of the Diagnosis and Treatment of Necrotizing Fasciitis

“…The usefulness of MRI in the diagnosis of necrotizing fasciitis has been supported in a study by Rahmouni et al, who in 36 patients were able to differentiate between non-necrotizing cellulitis that would respond to medical treatment and severe, necrotizing infections that required rapid, life-saving surgery (16). In a reported case of necrotizing fasciitis, MRI provided dramatic evidence of an inflammatory process infiltrating the fascial planes (8).…”

“…We have reported appropriate radiological studies that allow an early diagnosis of necrotizing infections (8). In addition, they permit visualization of the location of the rapidly spreading infection.…”

“…In addition, they permit visualization of the location of the rapidly spreading infection. Plain radiographs, often obtained to detect soft tissue gas that is sometimes present in polymicrobial or clostridial necrotizing fasciitis, are of no value in the diagnosis of necrotizing infections (8,9). In their study of 29 patients with necrotizing soft tissue infections, Lille et al reported that non-diagnostic radiographs correlate with a delay in operative intervention and consequent increased morbidity and mortality (9).…”

An unusual infection of cervicofacial area caused by dental pathology: flesh-eating syndrome

“…can provide an important evidence of an inflammatory process infiltrating the fascial planes in the early stage of NF [19]. We prefer CT scan for all patients to confirm the diagnosis of NF.…”

Group a streptococcus necrotizing fasciitis

“…30 Radiographic studies should not delay surgical evaluation if necrotizing fasciitis is suspected. Rather, it should serve to expedite and direct surgical intervention.…”
