Facial and Skeletal Muscle Magnetic Resonance Imaging in Oculopharyngodistal Myopathy

Abstract

Objective: Oculopharyngodistal myopathy (OPDM) has been reported as a rare, adultonset hereditary muscle disease. Patients show progressive oculopharyngeal and distal limb muscle involvement. As the genetic defect underlying OPDM is not known yet, the diagnosis currently rests upon clinical and histopathological features. This study was aimed at investigating patterns of muscle alterations of OPDM patients by MRI and to search for possible clues to make differential diagnosis by using a noninvasive method.
