Cardiac inflammatory pseudotumors are rarely observed. Their etiology might include immunologic abnormalities, fibrogenetic disorders, specific reactions to infections or abnormalities related to trauma, necrosis, or neoplasm. Life-threatening ventricular tachycardia and cases of sudden death related to cardiac tumors have been reported. The present report describes and discusses diagnostic and therapeutic solutions for the treatment of nonsarcoid multiorgan pseudotumors with cardiac involvement.
A 38-year-old woman presented to the clinic with symptomatic ventricular tachycardia. As coronary artery disease, cardiomyopathy, and channelopathy were ruled out, and electrocardiograms were not typical of idiopathic arrhythmia, the patient underwent detailed diagnostics which included targeted endomyocardial biopsy, which revealed a cardiac inflammatory pseudotumor. Laborious testing (and eventually, antibiotic therapy) led to ex juvantibus diagnosis of multiorgan disseminated brucellosis with cardiac involvement. Treatment with ceftriaxone, doxycycline, and rifampicin resulted in a complete resolution of all lesions after 3 months, and sustained recovery was observed during a 5-year follow-up. As the risk of ventricular tachycardia could not be reliably predicted, the patient had a subcutaneous implantable cardioverter-defibrillator implanted.
A vast diagnostic armamentarium of modern medicine allowed us to diagnose an unsuspected and rare cardiac inflammatory pseudotumor. In the case of travelers, the possibility of regionally specific illnesses, especially infections, must be taken into consideration as possible causes of arrhythmias. Cardiac magnetic resonance imaging may be useful in patients with ‘idiopathic ventricular tachycardias’ to detect non-apparent myocardial lesions which may result from the underlying cause of the arrhythmia.
