Posterior intrathoracic neurinoma cure: a transforaminal resection after a thoracotomy.

Abstract

Posterior intrathoracic neurogenic tumors often have an intraforaminal extension. Ten percent have an extension intraspinal and are called "dumbbell tumors." The surgically recommended techniques used to treat these conditions may have been applied too systematically, mainly when the diameter of the foramen was obviously enlarged and the possibility of removing the tumor existed. We report two cases to stress the importance of assessing the size of the intervertebral foramina in planning neurinoma cure.
