Diffuse Idiopathic Skeletal Hyperosteosis with Parsonage– Turner Syndrome Appearance

Diffuse idiopathic skeletal hyperosteosis is recognized by the appearance of at least 3 bony bridges in the anterolateral spine, and rarely it can be confused with Parsonage–Turner syndrome A 50-year-old male patient was admitted for left shoulder pain for approximately 2 years. There were weaknesses in deltoid, supraspinatus, biceps brachi, and wrist extension muscles. Hypoesthesia was found in the left C6 dermatom. Deep tendon reflexes were mildly hyperactive bilaterally and symmetrically. No pathological upper motor neuron signs were seen. On cervical magnetic resonance imaging T2-weighted images, hypointense osteophytes are observed in the posterior corners of 4 consecutive vertebral corpses, and disc spaces are preserved in the sagittal section. There were no findings in electromyography similar to Parsonage–Turner syndrome or cervical radiculopathy. Sacroiliac joint magnetic resonance imaging was found normal. According to the cervical computed tomography and dorsal radiography, we thought that the patient was diagnosed as diffuse idiopathic skeletal hyperosteosis syndrome. Even if Parsonage–Turner syndrome is considered in adult male patients presenting with shoulder pain, weakness, and atrophy of the shoulder girdle muscles, it would be valuable to consider diffuse idiopathic skeletal hyperosteosis disease involving the cervical vertebrae in the differential diagnosis.
