Intracanalicular Osteochondroma in the Lumbar Spine

Abstract

Osteochondroma is a common benign bone tumor that is relatively rare in the spine. Here, we report two cases of symptomatic solitary osteochondroma of the lumbar spine. The first case was a 61-year-old man who presented with a 2-year history of right leg numbness. Imaging findings showed that the cause of the radiculopathy was osteochondroma of the right inferior articular process at L4. The tumor was removed en bloc, and the numbness resolved. The second case was a 62-year-old man with osteochondroma of the right superior articular process at L5 that caused pain and numbness in the right leg. En bloc resection of the osteochondroma with the ligamentum flavum relieved the symptoms. Spinal osteochondroma occurs relatively frequently in elderly individuals compared with peripheral lesions and mimics a degenerative spinal disorder. Careful physical examination and imaging evaluation can reveal this tumor and surgery is effective for relieving the symptoms.

Diagnostic features of lumbar canal osteochondroma and review of literature

“…Osteochondropathy can be completely asymptomatic [15].A lot of people are found by accident on imaging tests.In general, asymptomatic lesions can be followed conservatively, and surgery can be Published by Francis Academic Press, UK -33-considered when the diagnosis is unclear, if the patient is in pain or has progressive neurological dysfunction [16].The surgery requires the removal of the entire tumor bone, including the cartilage cap.…”

Osteocondroma espinal; visión general y conceptos básicos

“…Se debe sospechar malignidad si las imágenes de resonancia magnética muestran que la cubierta del cartílago mide más de 2 cm en adultos y más de 3 cm en pacientes pediátricos. 12,13 Otra modalidad diagnóstica disponible es el gammagrama óseo, en donde el tejido cartilaginoso de la exostosis puede (o no) mostrar aumento de la captación del radiofármaco, tanto en condiciones normales como en transformación maligna (condrosarcoma secundario). Por tanto, no sería de gran utilidad para diferenciar entre lesiones cartilaginosas benignas y malignas.…”
