Calvarial lesions often present themselves as clinically silent findings on skull radiographs or as palpable masses that may cause localized pain or soreness. This review aims to explore the radiographic, computed tomography (CT), and magnetic resonance imaging (MRI) characteristics of calvarial neoplastic, inflammatory, and congenital lesions that are common in adults in order to facilitate a structured approach to their diagnosis and limit the differential diagnosis. In addition to reviewing the literature, we reviewed the records of 141 patients of the Montreal Neurological Institute and Hospital with radiologically documented calvarial lesions between 2001 and June 2009. CT is ideal for detecting bony lesions and is helpful in precisely localizing a lesion pre-surgically. MRI is best at identifying intradiploic lesions before they affect the cortical tables and is able to establish extraosseous involvement, especially when paramagnetic contrast is employed.
颅骨病变在颅骨 X 线片上常表现为临床无症状发现，或为可触及的肿块，可引起局部疼痛或不适。本综述旨在探讨成人中常见的颅骨肿瘤、炎症和先天性病变的放射学、计算机断层扫描（CT）和磁共振成像（MRI）特征，以便对其进行有针对性的诊断，并限制鉴别诊断。除了回顾文献，我们还回顾了 2001 年至 2009 年 6 月间，在蒙特利尔神经学研究所和医院的 141 例有影像学记录的颅骨病变患者的病历。CT 非常适合检测骨病变，并有助于在术前精确定位病变。MRI 最适合在颅骨板内病变影响皮质板之前识别，并且能够确定骨外受累，尤其是在使用顺磁对比剂时。
