Abstract
The pathological findings of an intradural and extramedullary cyst in the mid cervical spinal canal are described in a 55 year old woman who presented with a short history of pain and paraesthesia of the right arm. Intradural well defined solitary cystic lesions in the spinal canal are uncommon, their pathogenesis is poorly understood, and their nomenclature is confusing. In this case the cyst was a bronchogenic cyst; these are a rare form of such cysts and they are thought to be a malformation arising from a split notochordal syndrome and not a teratoma.
