The skull base is divided into three parts: anterior, central and posterior. Numerous foramina are located in the skull base and transmit important neurovascular structures. Numerous types of tumor can be observed at the skull base. They are classified as anterior, central and posterior skull base tumors. They are also divided into three groups according to their origin: tumors arising from the skull base itself, intracranial tumors and extracranial tumors invading the skull base. Imaging is very important for diagnosis, treatment and follow-up of patients with skull base tumors. Magnetic resonance imaging is the most useful modality as it visualizes the lesion on different planes and permits the planning of therapy. Computed tomography depicts the osseous lesions more precisely and may be necessary before surgery. Catheter angiography is now in most cases replaced by magnetic resonance angiography. Interventional neuroradiology is necessary if the lesion is highly vascularized or if a vessel is encased in the tumor.
前部、中部和后部。颅底有许多孔，这些孔传递重要的神经血管结构。颅底可观察到多种类型的肿瘤。它们被分类为前颅底肿瘤、中颅底肿瘤和后颅底肿瘤。它们还根据起源分为三组：起源于颅底本身的肿瘤、颅内肿瘤和侵犯颅底的颅外肿瘤。影像学对于颅底肿瘤患者的诊断、治疗和随访非常重要。磁共振成像最为有用，因为它能在不同平面上显示病变，并有助于制定治疗方案。计算机断层扫描能更精确地描绘骨质病变，在手术前可能是必要的。目前在大多数情况下，导管血管造影已被磁共振血管造影所取代。如果病变血管丰富或血管被肿瘤包裹，则需要进行介入神经放射学检查。
