ABSTRACT
BACKGROUND:
Among chondrosarcomas arising from bones and soft tissues, mesenchymal chondrosarcoma (MCS), especially primary spinal intradural extramedullary MCS, is extremely rare, and only 18 cases have been reported to date. We report an adult case of this rare condition mimicking meningioma. CASE DESCRIPTION A 42-year-old woman presented with paraplegia and sensory disturbance associated with right-sided Brown-Séquard syndrome following back pain. Magnetic resonance imaging showed an intradural mass in the right dorsal spinal canal with homogeneous enhancement and dural tail sign at the T8 level. Computed tomography demonstrated a calcified portion in the mass. Following T7-8 laminectomies, an intradural extramedullary tumor was completely removed after detaching the tumor from the dura mater. The histopathologic diagnosis was MCS, and positron emission tomography showed no metastatic lesions at other sites. The patient did not receive adjuvant therapy, and magnetic resonance imaging revealed no evidence of recurrence during 2-year follow-up.CONCLUSIONS:
Primary spinal intradural extramedullary MCS has been reported to have a better prognosis than MCS occurring in other regions. In a case with early complete surgical resection, adjuvant therapy should be considered at the time of recurrence.Palavras-chave
