? 2022 Elsevier Inc.Ependymomas are rare primary tumors of the brain and spinal cord that arises from the ependymal cell layer. Cranial ependymomas commonly occur in the posterior fossa; however, approximately 30% of all tumors can be found in the supratentorial region. Supratentorial ependymomas have a shorter progression-free and overall survival than their infratentorial counterparts. We present the case of a 47-year-old man who presented with mild left-sided hemiparesis and confusion secondary to a right-sided 8.5 × 6.0 × 6.0 cm frontotemporal neoplasm encasing the ipsilateral internal and middle cerebral arteries. The patient had undergone a suboccipital craniectomy for resection of a posterior fossa ependymoma at 6 years of age (41 years ago). After multidisciplinary discussion, we performed a right frontotemporal craniotomy for tumor resection (Video) using intraoperative navigation, ultrasound, and intraoperative neurophysiological monitoring. While skeletonizing branches of the middle cerebral artery, an M3 branch was injured inadvertently and repaired immediately. Histopathologic specimens were consistent with ependymoma (World Health Organization grade II). A near-total resection was achieved. The patient developed a transient left-sided hemiparesis but improved to full strength on discharge from the hospital.
