Cardiac mucormycosis with T-cell immunodeficiency

Area of Science:

• Pediatric Cardiology
• Infectious Diseases
• Immunology

Background:

• Mucormycosis is a rare but severe fungal infection, particularly in immunocompromised individuals.
• Cardiac involvement in pediatric mucormycosis is exceptionally uncommon.
• Early diagnosis and management are crucial for patient outcomes.

Observation:

• A 2-year-old child presented with fever and an unusual mitral valve mass.
• Surgical excision and histopathology confirmed the mass as mucormycosis.
• Four months later, the child experienced central nervous system (CNS) embolization and cardiac lesion recurrence.

Findings:

• Histopathological analysis confirmed mucormycosis as the cause of the cardiac mass.
• Further investigations identified an associated T-cell immunodeficiency.
• The recurrence and CNS involvement highlight the aggressive nature of the infection in this context.

Implications:

• This case underscores the importance of considering mucormycosis in pediatric cardiac masses, especially with atypical presentations.
• Identifying underlying immunodeficiencies, such as T-cell defects, is critical for managing recurrent fungal infections.
• This highlights the need for comprehensive diagnostic workups in pediatric patients with severe fungal infections and recurrent disease.
