Infective Endocarditis Presenting as Rhabdomyolysis and Muscle Abscess: A Case Report.

Area of Science:

• Cardiology
• Infectious Diseases
• Nephrology

Background:

• Rhabdomyolysis, a skeletal muscle degradation, has diverse causes.
• Infective endocarditis (IE) is an infection of the heart's inner lining.
• IE-induced rhabdomyolysis is exceptionally rare.

Observation:

• A patient presented with rhabdomyolysis, a muscular abscess, and acute renal failure.
• Infective endocarditis was identified as the underlying cause.
• The causative agent was identified as *Streptococcus dysgalactiae*.

Findings:

• Successful management of IE-related rhabdomyolysis and acute kidney injury was achieved.
• Treatment involved hydration and targeted antibiotic therapy.
• The case highlights *Streptococcus dysgalactiae* as an atypical IE pathogen.

Implications:

• Clinicians should consider IE in unexplained rhabdomyolysis, even with atypical presentations.
• Recognizing extracardiac manifestations of IE is crucial for timely diagnosis.
• This case broadens the understanding of IE's diverse clinical spectrum.
