Posterior cranial fossa meningiomas represent approximately 9% of all the intracranial meningiomas. Despite the recent reports of radiation therapy in the management of these tumors, surgical resection continues to be the first line of treatment method aiming the permanent meningioma eradication. The evolution of imaging studies improved the preoperative evaluation of meningiomas providing greater anatomical detail of small structures not previously visualized. Nonetheless, the preoperative radiological evaluation should go beyond the differential diagnosis of a posterior fossa tumor. Anatomo-radiological assessment of meningiomas is discussed in detail. Based on our clinical experience, literature review, and case illustration, we highlight important preoperative anatomo-radiological aspects of posterior fossa meningiomas and their implications in the surgical management of these tumors.
后颅窝脑膜瘤约占所有颅内脑膜瘤的9%。尽管最近有关于放射治疗这些肿瘤的报道，但手术切除仍然是旨在永久根除脑膜瘤的一线治疗方法。影像学研究的发展改善了脑膜瘤的术前评估，提供了以前无法看到的小结构的更详细解剖细节。尽管如此，术前放射学评估不应局限于后颅窝肿瘤的鉴别诊断。本文将详细讨论脑膜瘤的解剖放射学评估。基于我们的临床经验、文献综述和病例说明，我们强调了后颅窝脑膜瘤重要的术前解剖放射学方面及其在这些肿瘤手术治疗中的意义。
