摘　　要：BACKGROUND Chordoma is a rare low-grade malignant tumor originating from embryonic notochordal tissue mainly occurring in the axial bone,mostly in the sphenooccipital junction and sacrococcyx,which accounts for approximately 1%of all malignant bone tumors and 0.1%–0.2%of intracranial tumors.Chordoma in the petrous mastoid region is rare.CASE SUMMARY We describe a 36-year-old male patient with chordoma in the left petrous mastoid region.The main clinical manifestations were pain and discomfort,which lasted for 2 years.Magnetic resonance imaging showed a lobulated mass in the left petrous mastoid with an unclear boundary and obvious enhancement.The tumor was completely removed after surgical treatment,and a histological examination confirmed that the tumor was a chordoma.During 5 years of follow-up,no clinical or radiological evidence of recurrence or metastasis was found.CONCLUSION Chordoma in the petrosal mastoid region is rare but should be included in differential diagnosis of petrosal mastoid tumors.
