A rare cardiac inflammatory pseudotumor was diagnosed in a patient with ventricular tachycardia. Successful antibiotic treatment for disseminated brucellosis resolved the cardiac lesions, highlighting the importance of considering infections in arrhythmias.
Area of Science:
- Cardiology
- Infectious Diseases
- Pathology
Background:
- Cardiac inflammatory pseudotumors are rare, with potential links to immunologic issues, infections, or trauma.
- Ventricular tachycardia and sudden death are risks associated with cardiac tumors.
- This report details the diagnosis and treatment of a non-sarcoid multiorgan pseudotumor involving the heart.
Observation:
- A 38-year-old woman presented with symptomatic ventricular tachycardia, with other cardiac causes ruled out.
- Endomyocardial biopsy revealed a cardiac inflammatory pseudotumor.
- Extensive testing led to a diagnosis of disseminated brucellosis with cardiac involvement.
Findings:
- Antibiotic therapy (ceftriaxone, doxycycline, rifampicin) resulted in complete resolution of cardiac lesions.
- A 5-year follow-up confirmed sustained recovery.
- A subcutaneous implantable cardioverter-defibrillator was implanted due to unpredictable ventricular tachycardia risk.
Implications:
- Advanced diagnostics can identify rare cardiac inflammatory pseudotumors.
- Infectious causes, particularly in travelers, should be considered for arrhythmias.
- Cardiac MRI may aid in detecting myocardial lesions in 'idiopathic ventricular tachycardias'.
