Cervical spine anomaly.

摘要

A 32-year-old man presented for an evaluation of his cervical spine to determine whether he had the same congenital anomaly that had been diagnosed in his three-year-old daughter; his daughter required surgery. The man was asymptomatic and had no other medical problems. He denied neck pain, upper and lower extremity numbness or weakness, and bowel or bladder changes. His vital signs were normal. He had full range of motion of his cervical spine with no pain, normal upper and lower extremity strength and sensation, and normal reflexes throughout. Cervical flexion and extension radiography were performed (Figures 1 and 2).
