A 49-year-old woman with a medical history of essential hypertension presented to the ED with severe pain in the left superior chest and dull aching pain in the upper flank, lasting for the last 2 days.

A 62-year-old man with a history of allergic rhinitis and lightheadedness was admitted after an episode of sustained ventricular tachycardia detected by Holter monitor. A chest CT revealed peribronchial nodules, and mediastinal and hilar lymphadenopathy. The findings raised concern for sarcoidosis. MRI and FDG PET/CT were performed and revealed cardiac sarcoidosis isolated to the right ventricle only. Sarcoidosis of the right ventricle, sparing the left ventricle, is an extremely uncommon entity.
