Microtopographical interrelations of the posterior cranial fossa structures in the presence of cholesteatoma were studied up intraoperatively in 36 cases and while the pathomorphological investigation conduction in 6 sectional observations. Cholesteatoma mostly localizes in cerebellopontile angle and more rarely--in the IV ventricle with craniospinal spreading. It is the tumor's capsule texture what causes dense adherence of cholesteatoma with surrounding cranial nerves, vessels, incorporated frequently in her structure together with underlying cerebral substance.
对36例胆脂瘤患者术中研究了后颅窝结构的微观地形学相互关系，并对6个切片观察进行了病理形态学研究。胆脂瘤大多位于小脑脑桥角，较少位于第四脑室并伴有颅脊播散。正是肿瘤的包膜质地导致胆脂瘤与周围颅神经、血管紧密粘连，这些结构常与下方的脑实质一起融入其结构中。
