[Benign vertebral osteoblastoma. Report of 6 cases]. / L'ostéoblastome bénin vertébral. A propos de 6 observations.

We present six cases of benign spinal osteoblastoma. This localization of this uncommon benign bone tumor occurring in young subjects is rare. The patients were explored with radiotomography, computed tomography, myelography and medullo-spinal angiography. These benign tumors may appear radiographically as pure bone lysis mimicking malignancy. The size of these tumors often leads to widening search for extension, particularly in recurrent, aggressive, multifocal forms which require wide resection, and sometimes total vertebrectomy. Medullo-spinal angiography can confirm the vascular involvement of the tumor nidus and is require to identify arteries supplying the spinal canal which would modify operative strategy.

[Endovascular treatment of iatrogenic false aneurysm in the right subclavian pit. Apropos of a case]. / Traitement endovasculaire d'un faux anévrysme iatrogène du creux sus-claviculaire droit. A propos d'un cas.

The authors report about one case of false aneurysm in the right subclavicular pit, which developed after iterative venous punctures in a 67-year-old woman. Surgery was excluded, and an endovascular treatment was decided, with an approach of the lesion by direct puncture in this case and the insertion of an inflatable balloon.
