congenital narrowing of cervical spinal canal
Congenital cervical spinal stenosis is a rare neurological disease characterized by a congenital narrowing of the bony anatomy of the cervical spinal canal (sagittal diameter <14mm), predisposing the individual to symptomatic neural compression, such as cramps, paresthesias, pain, muscle hypertonia and weakness, myelopathy and sphincter disturbances.
