| ABSTRACT |
|
Chondroma is a benign bone tumor and rarely involves the spine ; even if this occurs however, neurological symptoms and signs rarely arise. We encountered one case of chondroma which developed in the posterior arch of the atlas. The patient complained of quadriparesis, hypesthesia, and urinary frequency. MR imaging showed that the tumor had compressed the cord dorsolaterally at the C1 level. It was completely removed, and the posterior arch of the atlas and surrounding ligamentum flavum disclosed hypertrophy.
Postoperatively, the neurological status of the patient improved. On pathologic examination, hypocellularity and mature hyaline cartilage was seen, as well as chondrocytes residing in the lacunae ; all these findings were compatible with benign chondroma. |
