How to Approach Anatomical Compartment; Extradural Foraminal Tumor

Spinal extradural foraminal neoplasms are uncommon lesions that are constricted at the point they penetrate the intervertebral foramina or dura mater. Because of their varied locations, extradural foraminal neoplasms have features, clinical symptoms, and pathological characteristics that are unique compared with the more common intradural extramedullary (IDEM) tumors, consequently, their surgical approach and treatment should be also differentiated. Surgically, extradural extension into the foramen necessitates a more or less important resection of the facet joints. This raises the question of spinal stability and the need for additional fixation. However, recent progression of anatomy-preserving minimally invasive surgical techniques along with the concomitant evolution of their tools allows for excellent exposure while limiting damage to surrounding tissues through a minimized surgical corridor or modified approach method, followed by safe and completed resection of these extradural foraminal neoplasms.
