Abstract

The authors describe the case history of a patient who was stabbed in the back of his neck with a knife and who later presented with a Brown-Séquard syndrome attributable to cervical spinal cord damage. Myelography and CT revealed a compressive extradural lesion shown at exploratory operation to be a loculus of cerebrospinal fluid (CSF). The loculus had formed as a consequence of leakage of CSF through a dural tear caused by the knife. Evacuation of this loculus resulted in some neurological improvement. The necessity of obtaining a clear history and of performing a thorough clinical examination is explained. The need to admit patients in whom stab wounds of the neck have transgressed subcutaneous fat is reiterated. Early referral to a neurosurgeon is advised for those patients with neurological deficits.
