Abstract

Background: A 54-year-old female was referred to our clinic with a lesion of the lower fourth ventricle extending to the median aperture. Here, we report the use a minimally invasive sub-occipital approach (MISA) as a safe and effective surgical management.

Method: We performed a MISA using a short midline incision and a 1-cm sub-occipital craniectomy. Dissection of the lesion was performed, and "en bloc" resection could be achieved. The lesion was confirmed to be a grade I sub-ependymoma.

Conclusion: MISA can be safely used when confronted to a lesion of the lower fourth ventricle.

Keywords: Micro-surgery; Minimally invasive surgery; Sub-ependymoma; Sub-occipital approach.
