Coccydynia due to a benign notochordal cell tumor

Spine (Phila Pa 1976). 2007 Jun 15;32(14):E394-6. doi: 10.1097/BRS.0b013e318067e33a.

Abstract

Study design: Case report.

Objective: To present a rare case of a notochordal cell tumor.

Summary of background data: We report on a 27-year-old female patient with pain at the lower back and muscle cramps in the area of the right hip. Image studies demonstrated a cystic lesion of the coccyx.

Methods: As clinical symptoms became chronic and were resistant to conservative treatment, a resection of the coccyx was performed.

Results: Histology revealed an intraosseous benign notochordal cell tumor. This tumor represents a recently described notochordal cell proliferation biologically distinct from chordomas.

Conclusions: Overdiagnosis of these notochordal cell proliferations as chordomas may occur if clinicians and pathologists are unfamiliar with the spectrum of notochordal proliferations.
