One of the most important and useful pieces of information in the preoperative evaluation of a large petroclival meningioma is the running course of the abducens nerve. The abducens nerve is small and has a long intracranial course, making it prone to compression by the tumor at various anatomical points. In relatively large tumors, it is difficult to confirm the entire course of the abducens nerve, even by heavy T2-thin slice imaging. We report a case of successful preoperative estimation of the course of the abducens nerve that aided in its complete preservation during the resection of a large petroclival tumor.
在大型岩斜脑膜瘤的术前评估中，最重要且有用的信息之一是展神经的走行过程。展神经细小，颅内走行较长，这使其在各个解剖部位容易受到肿瘤的压迫。对于相对较大的肿瘤，即使采用重T2加权薄层成像，也难以确认展神经的全程。我们报告了一例成功术前评估展神经走行的病例，该评估有助于在切除大型岩斜肿瘤时完整保留展神经。
