Summary

Erosions, caused by a vertebral artery loop, of the pedicles and vertebral bodies in the area of C2−C6 were found in nine patients, in a total of 12 intervertebral spaces. Two of the cases in which the changes seen in plain radiographs were considered bilateral, were confirmed by angiography of the aortic arch. A tortuous vertebral artery sometimes produces symptoms provoked by nerve root compression. To keep this differential diagnosis in mind is at least equally important when a tumor enlarging the foramen is suspected.

Résumé

Les auteurs décrivent chez nenf malades une érosion des pédicules et des corps vertébraux de C2−C6 au niveau de 12 espaces intervertébraux. Cette érosion était due à une boucle de l'artère vertébrale. Dans deux cas les lésions visibles sur les radiographies conventionnelles semblaient bilatérales et furent confirmées par crossographie. Une artère vertébrale tortueuse peut provoquer des symptomes de compression d'une racine nerveuse. Il est très important de connaître ce diagnostic différentiel lorsqu'on suspecte une tumeur envahissant le canal de conjugaison.

Zusammenfassung

Bei 9 Patienten wurden Erosionen der Halswirbelkörper in Höhe von C2 bis C6 beobachtet, die durch Schlingen der A. vertebralis hervorgerufen wurden. Eine geschlängelt verlaufende A. vertebralis kann durch Wurzelkompression neurologische Symptome bedingen. An diese Differentialdiagnose ist zu denken, wenn ein erweitertes Foramen besteht.
