| Summary: | Giant intracranial epidermoids (giant IEs) often extend into multiple compartments within the cranial vault and if tumor fragments are left behind during resection, recurrence is inevitable. The endoscope can be used to identify residual epidermoid and help achieve safe, maximal resection. We present two patients with giant IEs who underwent resections. The endoscope was used in final measure to survey the surgical beds. Residual tumors were identified in both cases, and further resections were performed. This report highlights the importance of an endoscopic survey after apparent gross-total resection of giant IEs. Keywords: Brain tumor, Recurrent endoscopy, Epidermoid cyst, Posterior fossa tumors
