Dumbbell-shaped thoracic chondroid chordoma mimicking a neurinoma.

A 31-year-old woman was admitted to the hospital with paraparesis and pyramidal signs. Magnetic resonance imaging disclosed a homogeneously enhanced mass occupying the spinal canal at the T1-T2 level and extending to the apical pleural space through the right intervertebral foramen.
