Imaging of the skull base presents many challenges due to its anatomical complexity, numerous normal variants and lack of familiarity to many radiologists. As the skull base is a region which is not amenable to physical examination and as lesions of the skull base are generally difficult to biopsy and even more difficult to operate on, the radiologist plays a major role in directing patient management via accurate image interpretation. Knowledge of the skull base should not be limited to neuroradiologists and head and neck radiologists, however, as the central skull base is routinely included in the field of view when imaging the brain, cervical spine, or head and neck with computed tomography or magnetic resonance imaging, and hence, its nuances should be familiar to general radiologists as well. We herein review the imaging findings of a subcategory of lesions of the central skull base, the 'do not touch' lesions.
由于颅底解剖结构复杂、存在众多正常变异且许多放射科医生对此缺乏了解，颅底成像面临诸多挑战。由于颅底区域不适合体格检查，且颅底病变通常难以进行活检，甚至更难进行手术，放射科医生在通过准确解读图像指导患者管理方面发挥着重要作用。然而，对颅底的了解不应仅限于神经放射科医生和头颈放射科医生，因为在用计算机断层扫描或磁共振成像对脑、颈椎或头颈进行成像时，中央颅底通常包含在视野范围内，因此，普通放射科医生也应熟悉其细微差别。我们在此回顾中央颅底病变的一个子类别——“不可触碰”病变的影像学表现。
