A gas filled intradural cyst associated with disc degeneration

Abstract

A case of a lumbar intradural, extramedullary gas filled cyst is described. This was associated with degenerative disc disease and presented with radicular signs and symptoms. The radiological differential diagnosis of such a mass includes infection and tumours. The association of intradural gas with degenerative disc disease is previously reported. This case further illustrates the association of degenerative disc disease with an intradural gas filled cyst and provides an interesting radiological differential diagnosis for an extramedullary intradural mass.
