Isolated Neck Extensor Myopathy: A Case Presentation of Rapid Onset and Spontaneous Recovery.

Abstract

Patients presenting with a chin-on-chest deformity, or dropped head syndrome, may have a diagnosis of isolated neck extensor myopathy (INEM). INEM is a diagnosis of exclusion occurring primarily in elderly patients. INEM usually has a benign progression, which may involve the shoulder girdle but does not advance to other muscle groups. Patients without an inflammatory etiology typically experience minimal or no recovery of their symptoms. Dropped head syndrome has various implications on a patient's quality of life and activities of daily living. We present a unique case of INEM with rapid onset and complete clinical recovery within a time frame of 4 months. V.
