A case of Klippel-Feil syndrome with adult-onset neurological symptoms.

Klippel-Feil syndrome is a rare congenital anomaly characterized by fusion of cervical vertebrae. We describe the case of a 45-year-old female presenting with nonspecific neurological symptoms which was discovered to be due to undiagnosed Klippel-Feil syndrome. This case is unique due to presentation in adulthood as this condition is usually diagnosed in childhood due to visual asymmetries. Additionally, we highlight the value of multimodal imaging and diagnostics when attempting to delineate overlapping pathologies related to the cervical spine.
