Abstract:
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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
