Abstract:
We present a rare case of necrotizing myositis predominantly caused by Enterococcus faecium in a 68-year-old healthy man, with concurrent Klebsiella pneumoniae bacteremia. The patient rapidly progressed from diarrhea and fever to septic shock, multiple organ dysfunction, and compartment syndrome of the left leg. Blood cultures grew K. pneumoniae, while deep tissue cultures identified E. faecium as the main pathogen in necrotic muscle. Emergent fasciotomy, serial debridements, and targeted antibiotics (meropenem and linezolid/vancomycin) led to full recovery. This first reported case highlights the underappreciated virulence of E. faecium in soft tissue infections and underscores the need for prompt imaging, surgical intervention, and comprehensive microbiological workup in severe infections. The case also emphasizes the importance of considering polymicrobial etiology and monitoring for antibiotic adverse effects.
Insights
Necrotizing myositis, a severe muscle infection, was primarily caused by Enterococcus faecium in a healthy adult. Prompt surgical intervention and antibiotics led to recovery, highlighting E. faecium
Area of Science:
- Infectious Diseases
- Microbiology
- Surgery
Background:
- Necrotizing myositis is a rare, rapidly progressive soft tissue infection.
- Enterococcus faecium is typically associated with urinary tract infections and endocarditis, not severe soft tissue infections.
- Polymicrobial infections can complicate the clinical presentation and treatment of severe sepsis.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
