脑膜瘤与瘤周脑水肿

Meningioma and peritumoral edema.

本文分析了１３２例脑膜瘤病人的临床和病理资料，探讨影响脑膜瘤瘤周脑水肿的各种因素。发现：伴有瘤周水肿者，病程进展迅速，头痛、呕吐、眼底水肿、癫痫、肢体感觉运动障碍和病理反射的发生率随水肿程度的加重而增高。血管瘤型、间变型、合体型及血管成份增多的脑膜瘤易产生瘤周水肿；而纤维型和砂粒型则较少伴瘤周水肿。若肿瘤位于中颅窝底、矢状窦旁、大脑凸面、大脑镰、嗅沟和蝶骨嵴外侧部位时易产生瘤周水肿；而位于后颅窝、鞍结节和侧脑室部位时则不易产生瘤周水肿。大中型较小脑膜瘤易产生瘤周水肿。

The clinical and pathological data of 132 patients with meningioma were reviewed and some factors affecting the peritumoral edema were studied.If a tumor has peritumoral edema, the clinical course progresses rapidly. The percentage of headache, vomiting, papilledema. sensory and motor disturbance, pathological reflexes and seizures became higher with the edema degree increasing.Angiomatous, anaplastic and syncytial mengioma,the tumor with increased vascularity, were associated with peritumoral edema frequently, while peritumoral edema were occasionally seen in psammomatous and fibrous types. They were often associated with peritumoral edema if the tumor located in the middle cranial fossa, the parasagital site, the convexity, the falx, the olfactory groove or the sphenoid wing. However the tumor was usually without peritumoral edema if it was located in the posterior cranial fossa, the tuberculum selae, and the lateral ventricles.
