Twenty-six cases of rare primary cranial vault tumors are reported, together with 4 cases of primary tumors of the base of the skull and 3 cases of monostotic cranial neuroblastoma. Whereas some rare primary cranial vault tumors may present with characteristic radiographic patterns (e.g. hemangioma, aneurysmal bone cyst, osteoma, progonoma), most of them can be recognised only after histology. The most frequent tumor in the region of previous irradiation is osteosarcoma. The only "common" primary bone tumor of the base of the skull is chordoma. The radiological differential diagnosis of primary tumors of the skull vault and base is discussed.
报告了26例罕见的原发性颅顶肿瘤，以及4例原发性颅底肿瘤和3例单发性颅骨神经母细胞瘤。虽然一些罕见的原发性颅顶肿瘤可能呈现出特征性的影像学表现（如血管瘤、动脉瘤样骨囊肿、骨瘤、促结缔组织增生性小圆细胞肿瘤），但大多数肿瘤只有在组织学检查后才能确诊。既往放疗区域最常见的肿瘤是骨肉瘤。颅底唯一的“常见”原发性骨肿瘤是脊索瘤。本文讨论了颅顶和颅底原发性肿瘤的放射学鉴别诊断。
