Abstract
BACKGROUND

Osteochondromas are the most common benign bone tumor, accounting for 36% of benign bone tumors. Often found within the appendicular skeleton, osteochondromas of the spine are rare, comprising 4% to 7% of primary benign spinal tumors.

CASE SUMMARY

We report a case of a solitary lumbar osteochondroma in an 18-year-old male with a history of a suprasellar pineal germinoma treated with combined chemotherapy and radiation. He underwent mass excision and partial laminectomy with the ultrasonic bone scalpel (Misonix, Farmingdale, NY, United States) at the L5 Level without the use of adjuvants. The patient returned to work and full activities without back pain at 3 mo postoperatively.

CONCLUSION

Osteochondromas are common tumors of the appendicular skeleton but rarely occur within the spine. This case discussion supplements current osteochondroma literature by describing an unusual presentation of this tumor.

Core Tip: Osteochondromas of the spine are a rare but treatable condition. For symptomatic lesions, complete resection is largely curative without adjuvant therapy. The patient in this case report was pain free at his post-operative visits without signs or symptoms of recurrence or complication. He returned to work as a manual laborer at 3 mo. Further reports of patients diagnosed with osteochondromas and a history of childhood radiation will enable better understanding of radiation-induced osteochondromas and the rates and locations at which they occur.
