Necrotising Fasciitis in the Elderly: A Double Delay

Abstract

Necrotising fasciitis is an uncommon and rapidly progressive infection of the subcutaneous tissues and fascia which results in necrosis. Without prompt and aggressive surgical intervention, it inevitably leads to severe sepsis and multiorgan failure with a high mortality rate. In general, the diagnosis of infection in the elderly is often difficult, regardless of the type of infection. We report a case of necrotising fasciitis in a 95-year-old lady. The patient presented with bowel and urinary symptoms as well as left leg pain suggestive of sciatica. There was no sign of cellulitis and intravenous antibiotic was started for a presumed urinary tract infection. The diagnosis of necrotising fasciitis was made only much later when crepitus was noted in her leg and radiological studies confirmed gas in the soft tissues. The patient and her family declined surgery and she subsequently died from septicaemia. This condition posed a diagnostic dilemma in the absence of fever, sudden onset of severe pain, and cutaneous findings. In order to reduce morbidity and mortality a high degree of suspicion is required to reach an early diagnosis for prompt surgical intervention.
