Rare presentation of sarcoidosis: Multimodal imaging diagnosis of cardiac involvement

We report a case of sarcoidosis with an unusual presentation, initially manifesting as bilateral pulmonary embolism and then as a cardiac form of the disease with an ominous clinical event consisting of sustained ventricular tachycardia. The diagnosis was established by clinical and magnetic resonan...
