Cerebello-pontine(CP) angle and prepontine epidermoid tumors are challenging lesions because they grow along the subarachnoid spaces around the very important neurovascular structures and often extend into the supratentorial compartment. They have typically been removed through a variety of anterolateral, lateral, and posterolateral cranial base microsurgical approaches. Sometime they were removed by the endoscope-assisted microneurosurgical (EAM) techniques. Here we report a CP angle and preontine epidermoid tumor extended to supratentorial compartment presented with trigeminal neuralgia that was removed by pure endoscopic visualization through retrosigmoid retromastoid lateral suboccipital approach. (The method of using endoscope along with surgical instruments passing along the sides of endoscope is termed as Endoscope-Controlled Microsurgery-ECM.) So far our knowledge, in the literature this type of report is probably very rare.
桥小脑角（CP）和脑桥前表皮样肿瘤是具有挑战性的病变，因为它们沿着非常重要的神经血管结构周围的蛛网膜下腔生长，并且常常延伸至幕上腔。它们通常通过各种前外侧、外侧和后外侧颅底显微手术入路进行切除。有时也通过内镜辅助显微神经外科（EAM）技术切除。在此我们报告1例延伸至幕上腔的桥小脑角和脑桥前表皮样肿瘤，该肿瘤伴有三叉神经痛，通过乙状窦后乳突后外侧枕下入路在纯内镜直视下切除。（将内镜与沿内镜侧面通过的手术器械一起使用的方法称为内镜控制显微手术-ECM。）据我们所知，文献中这类报道可能非常罕见。
