Epidermoid tumors are rare benign neoplasms. They commonly occur in the parasellar region and the cerebellopontine angle but may sometimes present in the so-called petroclival region, or beyond the boundaries of this location. For those that are localized in multiple compartments, staged surgeries, extensive transtemporal approaches, or somewhat limited extended middle fossa approach are generally performed. Although a good resection can be achieved by these approaches, they carry relatively high morbidity and mortality. We report a case of epidermoid tumor with infra- and supratentorial extensions, and propose a combined retrosigmoid-paramedian supracerebellar transtentorial approach as an alternative to classical transtemporal approaches.
