Background:
Meningiomas arising from the dorsum sellae and upper clival region are extremely rare and pose significant surgical challenges due to their deep midline location and intimate relationships with critical neurovascular structures. Optimal surgical management remains controversial.
Observations:
The authors present the case of a 66-year-old woman with progressive bilateral visual loss secondary to a large dorsum sellae meningioma. The tumor was resected through a single-stage mini-combined transpetrosal approach. This approach enabled early devascularization, clear visualization of neurovascular anatomy, and preservation of critical structures. The patient had a favorable postoperative course without complications.
Lessons:
The mini-combined transpetrosal approach provides a versatile and effective surgical corridor for tumors of this region. Careful preoperative planning and detailed knowledge of microsurgical anatomy are essential to maximize tumor removal and minimize morbidity. https://thejns.org/doi/10.3171/CASE25839.
