Subaxial cervical foraminal chondromas: case-based discussion on surgical management.

Cervical foraminal chondromas are benign lesions that may require surgical resection when symptomatic due to radicular and/or spinal cord compression. The aim of surgery is to achieve gross tumor removal while preserving neurological function and spine stability. The authors describe a case of subaxial foraminal chondroma with a systematic review of the literature on patients with cervical chondromas. In the reported case, the authors used a retrojugular approach to remove a C6-C7 right chondroma without the need for spinal stabilization. Literature review identified a total of 11 patients who underwent surgery for subaxial foraminal chondroma. The mean age at diagnosis is 33.6 years (range: 10–73). Most patients report neurological symptoms at the time of diagnosis. The most frequently involved vertebral level is C4-C5 (54.6%, 6/11). Preoperative foraminal enlargement is present in 63.6% (7/11) of patients. Surgical resection is performed via an anterior approach in 18.2% (2/11) of patients, with vertebral body resection and concomitant cervical instrumentation. The anterolateral approach is selected in 27.2% (3/11) of patients, and the posterior approach in 54.6% (6/11) of patients, with only one patient requiring both anterior and posterior instrumentation. The choice of surgical access for subaxial foraminal chondroma can be challenging due to the anatomical location of the tumor in relation to the cervical nerve roots and spinal cord. Accurate approach selection is key to achieving complete tumor removal while preserving cervical spine stability. [ABSTRACT FROM AUTHOR]
