Severe rhabdomyolysis with myocarditis in a 2-year-old child

Area of Science:

• Pediatric critical care medicine
• Infectious diseases
• Muscle physiology

Background:

• Rhabdomyolysis in children often follows viral infections and typically presents with mild symptoms.
• Severe rhabdomyolysis without underlying conditions is uncommon in pediatric populations.
• Creatine kinase levels are key biomarkers for diagnosing muscle injury.

Observation:

• A previously healthy child developed acute rhabdomyolysis post-viral infection.
• The child experienced severe muscle involvement, leading to respiratory arrest.
• Cardiac dysfunction and myoglobinuria were observed, but renal function remained intact.

Findings:

• This case demonstrates a rare, severe manifestation of post-viral rhabdomyolysis in a child.
• The patient exhibited significant respiratory and cardiac compromise.
• Absence of underlying metabolic or rheumatologic disease underscores the severity of the viral trigger.

Implications:

• Highlights the potential for severe complications from seemingly common viral infections in children.
• Emphasizes the need for vigilant monitoring in pediatric cases of rhabdomyolysis, even without predisposing factors.
• Suggests viral infections can trigger severe, multi-systemic inflammatory responses in susceptible children.
