摘要

Objective: We reviewed 17 cases of primary intracranial extradural meningiomas (PIEMs) (including our 5 cases) reported in the literature so as to develop a better understanding of their clinical characteristics, treatment, and prognosis. Materials and Methods: The clinical data of 17 cases of PIEMs, including our 5 cases, were analyzed on their demographic features, presenting symptoms and duration, imaging and surgical findings, surgical results, pathologic grades, histologic subtypes, and follow-up results. Results: PIEMs accounted for 0.04% to 0.14% of all meningiomas. The most common presenting symptom (41.2%) was a painless, gradually expanding mass in the region of the lesion. PIEMs being located in skull convexities constituted 88.2% of all cases, whereas skull bases only 11.8%. All PIEMs patients were uneventful perioperatively after complete resection of tumor except 1 who died of primary cardiac arrest during operation. A total of 88.2% of PIEMs were grade I, 11.8% grade II. Ten cases of PIEMs were given a mean 2.16-year follow-up. As a result, no recurrence and death were found. Conclusions: PIEMs have some marked clinical characteristics. Total tumor removal together with a wide excision of all involved tissues followed by the reconstruction of tissue defects is the best surgical project. The prognosis is excellent after surgical complete resection.
