Benefit of magnetic resonance–conditional cardiac resynchronization therapy defibrillator: A case of cardiac sarcoidosis–involved cervical extradural lesion

. 2015 Dec 1;2(1):88–91. doi: 10.1016/j.hrcr.2015.11.003

KEY TEACHING POINTS

•
Sarcoidosis is a granulomatous disease that may involve multiple organs, including the heart and the nervous system. Hence, magnetic resonance imaging (MRI) is an important imaging modality for diagnosing and evaluating disease development.
•
In the past, it was impossible to perform magnetic resonance (MR) scanning for extracardiac lesions in patients with cardiac sarcoidosis requiring the implantation of traditional cardiac devices. Recently, MR-conditional devices have become available.
•
We describe a patient with cardiac sarcoidosis involving a cervical extradural lesion in whom the efficacy of corticosteroid treatment for spinal lesion could be clearly assessed by MRI after implanting an MR-conditional cardiac resynchronization therapy defibrillator.
