Although rare, skull vault lesions include a vast array of pathology encompassing infection, benign, and malignant bone tumors. Given the large range of potential diagnoses, it is crucial to identify imaging features to differentiate one from another, ensuring early diagnosis. Radiographs are still valuable in modern radiology but have largely been superseded by computed tomography (CT) due to its high spatial resolution. Both are especially important in developing countries where access to magnetic resonance imaging (MRI) may be limited.There are currently several publications outlining imaging appearances of skull vault lesions. However, the majority of literature is dated, with the last dedicated textbook published in 1980 (Principles of X-ray diagnosis of the skull). Despite overlapping features, a few lesions have "aunt minnie," type classical characteristics, which we will highlight. Most vault lesions also appear as a spectrum depending on location and the exact stage of the disease. A small subset within each disease entity also has atypical features not widely discussed in the current literature. In this pictorial review, we hope to focus on radiographic and CT imaging appearances to help differentiate between various skull vault lesions.
虽然罕见，但颅盖病变包括一系列广泛的病理学情况，涵盖感染、良性和恶性骨肿瘤。鉴于潜在诊断范围广泛，识别影像学特征以相互区分并确保早期诊断至关重要。在现代放射学中，X线平片仍然具有价值，但由于其高空间分辨率，已在很大程度上被计算机断层扫描（CT）所取代。在发展中国家，这两种检查尤为重要，因为在这些国家，磁共振成像（MRI）的可及性可能有限。目前有几篇关于颅盖病变影像学表现的出版物。然而，大多数文献都比较陈旧，最后一本专门的教科书出版于1980年（《颅骨X线诊断原理》）。尽管存在重叠特征，但一些病变具有典型的“一目了然”特征，我们将予以强调。大多数颅盖病变也会根据位置和疾病的确切阶段呈现出一系列表现。每个疾病实体中的一小部分也具有当前文献中未广泛讨论的非典型特征。在本图像综述中，我们希望聚焦于X线平片和CT成像表现，以帮助区分各种颅盖病变。
