MR imaging of a case of a dumbbell-shaped spinal schwannoma with intramedullary and intradural-extramedullary components

We present here a case of intramedullary- and extramedullary-intradural, dumbbell-shaped schwannoma that developed in the upper thoracic cord in a middle-aged man. Before surgery, the tumor was clearly revealed as a mass with two components, intramedullary and extramedullary, on MRI, and it could be...

Description
Summary:We present here a case of intramedullary- and extramedullary-intradural, dumbbell-shaped schwannoma that developed in the upper thoracic cord in a middle-aged man. Before surgery, the tumor was clearly revealed as a mass with two components, intramedullary and extramedullary, on MRI, and it could be useful for operation. We discuss the possible pathogenesis of this tumor.
