Dorsal scalloping by calcified disc herniation.

SUMMARY OF BACKGROUND DATA

Disc herniation responsible for scalloping of vertebral body had been reported only at the lumbar level.

RESULTS

The authors report on an unusual etiology of dorsal scalloping. A voluminous and calcified dorsal disc herniation was responsible for this, and within the center of the mass there was an unexpected hypersignal on nuclear magnetic resonance imaging.

CONCLUSION

Scalloping does not preclude disc herniation, even at the dorsal level. Hyperintensity in T1-weighted images can reveal calcifications, as indicated in previous studies.
