Klippel-Feil syndrome revealed by post-traumatic neck pain: Case report and literature review.

Klippel-Feil syndrome (KFS) is a congenital anomaly involving the fusion of two or more cervical vertebrae. It is characterized by a low hairline at the nape of the neck, a short neck, and a limited range of motion. Here, we present the case of a 10-year-old girl who suffered brain trauma in a motor vehicle accident and subsequently experienced persistent occipital headaches and dizziness. A brain computed tomography scan performed to evaluate these symptoms revealed incomplete fusion of two cervical vertebrae (C2-C3), leading to a diagnosis of KFS. Magnetic resonance imaging of the spine was conducted to investigate potential spinal abnormalities. In this article, we discuss the pathogenesis, associated abnormalities, subtypes, complications, and differential diagnosis of KFS. There is no cure for KFS. Treatment requires a multidisciplinary approach involving neurologists, orthopedic surgeons, pediatricians, physical therapists, and neurosurgeons, depending on the severity of the symptoms.
