Chordomas are rare tumors of notochordal origin which arise in the sacral, vertebral, and craniocervical areas. Most patients with craniocervical chordomas have either neurological or ophthalmological symptoms. A patient presented with a parotid mass which was initially diagnosed as benign mixed tumor. One and one-half years later, this patient was found to have an extensive intracranial tumor which was diagnosed as chordoma. Treatment consisted of subtotal surgical excision and radiotherapy. This case demonstrates an unusual presentation of an unusual tumor and the difficulty that may arise in in diagnosing these tumors.
脊索瘤是一种起源于脊索的罕见肿瘤，发生于骶骨、脊椎和颅颈区域。大多数颅颈脊索瘤患者有神经或眼科症状。一名患者出现腮腺肿块，最初被诊断为良性混合瘤。一年半后，该患者被发现患有广泛的颅内肿瘤，诊断为脊索瘤。治疗包括次全手术切除和放疗。该病例显示了一种罕见肿瘤的不寻常表现以及诊断这些肿瘤可能遇到的困难。
