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. Surgical resection was achieved using a laminectomy and complete facetectomy. Histological examination indicated chondroid chordoma. The patient received postoperative proton radio-therapy. Chondroid chordoma is a subtype of chordomas with better prognosis, and it may appear as a dumbbell-shaped tumor as previously described in classical chordomas.
