title: Unresectable cardiac pseudoneoplasms causing ventricular tachycardia.
abstract: Cardiac pseudoneoplasms are rare and benign. According to World Health Organization, they are classified as tumor-like lesions. We report two patients with recurrent ventricular tachycardia (VT) in whom magnetic resonance imaging revealed a pathological mass occupying a large part of the left ventricle. The localization of both tumors precluded the possibility of resection; thus, only surgical biopsy was performed. After deducting the prospect of malignancy of the tumors, we treated both patients with amiodarone and implantation of a cardioverter-defibrillator [implanted cardioverter/defibrillator (ICD)]. VT is one of many probable symptoms indicating a tumor within the heart; therefore, treatment with an ICD should only be considered after a more thorough diagnosis.
