Late enhancement on cardiac computed tomography in a patient with cardiac sarcoidosis.

Cardiac computed tomography (CT) angiography permits detection of myocardial scars through "late enhancement." We report the case of a patient with suspected cardiac sarcoidosis. Because of implanted defibrillator leads, magnetic resonance imaging was not possible. Dual-source CT with intravenous contrast injection was used as an alternative technique to detect late myocardial enhancement. A typical pattern of myocardial scarring allowed us to establish the diagnosis of cardiac sarcoidosis. CT imaging may be an alternative diagnostic tool to visualize late enhancement in patients with contraindications to magnetic resonance imaging.
