Abstract
BACKGROUND
Chordoma is a rare low-grade malignant tumor originating from embryonic notochordal tissue mainly occurring in the axial bone, mostly in the spheno-occipital 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.
Core Tip: Chordoma is a rare disease, especially in the petrous mastoid region. Its imaging findings have rarely been reported, and an understanding of its magnetic resonance imaging findings is lacking. However, in the differential diagnosis of petrous mastoid tumors, chordoma should be considered, especially when lobulated masses are found.
