An expanded endoscopic endonasal approach (eEEA) provides direct access to the tumor with no need for cerebral retraction or manipulation of neurovascular structures. Herein, we present a case of a large temporal fossa extradural lesion with secondary invasion of the sella, clivus, and temporal and infratemporal fossae in a 49-year-old male with severe vision loss. A transpterygoid transmaxillary approach was performed. Gross-total removal was achieved and pathology revealed the diagnosis of ATS. Visual function fully recovered in the right side and the patient has been uneventfully followed since surgery. **Intro music: "Daybreak" by Graeme Rosner |
