目的：探讨神经母细胞瘤颅面骨转移的CT和 MRI特征性表现。方法：回顾性分析6例经病理证实的神经母细胞瘤颅面骨转移患者的CT和 MRI资料，分析其影像学特征。6例均行头颅CT平扫，其中2例行头颅 MRI 平扫和增强检查，6例中5例行腹部CT平扫及增强检查，1例行腹部 MRI平扫及增强检查。结果：6例均为双侧颅面骨受累，主要CT表现为颅面骨骨质破坏、骨膜下垂直骨针和软组织肿块，软组织肿块中可见钙化；主要 MRI表现为颅骨骨质破坏并软组织肿块，其内有钙化灶，肿块于T1 WI上呈等信号，T2 WI 呈稍高信号，增强后可见肿块和邻近脑膜有不均匀轻度强化。5例腹部CT显示腹膜后肿块并钙化，增强后有不均匀强化。1例 MRI显示腹膜后肿块。结论：神经母细胞瘤颅骨转移的CT和 MRI表现有一定特征性，CT和 MRI对本病的诊断有重要价值。
目的：探討神經母細胞瘤顱麵骨轉移的CT和 MRI特徵性錶現。方法：迴顧性分析6例經病理證實的神經母細胞瘤顱麵骨轉移患者的CT和 MRI資料，分析其影像學特徵。6例均行頭顱CT平掃，其中2例行頭顱 MRI 平掃和增彊檢查，6例中5例行腹部CT平掃及增彊檢查，1例行腹部 MRI平掃及增彊檢查。結果：6例均為雙側顱麵骨受纍，主要CT錶現為顱麵骨骨質破壞、骨膜下垂直骨針和軟組織腫塊，軟組織腫塊中可見鈣化；主要 MRI錶現為顱骨骨質破壞併軟組織腫塊，其內有鈣化竈，腫塊于T1 WI上呈等信號，T2 WI 呈稍高信號，增彊後可見腫塊和鄰近腦膜有不均勻輕度彊化。5例腹部CT顯示腹膜後腫塊併鈣化，增彊後有不均勻彊化。1例 MRI顯示腹膜後腫塊。結論：神經母細胞瘤顱骨轉移的CT和 MRI錶現有一定特徵性，CT和 MRI對本病的診斷有重要價值。

Objective:To investigate the characteristic findings of metastatic neuroblastoma in craniofacial bones. Methods:CT and MRI features of six children with pathologically confirmed metastatic neuroblastoma in craniofacial bones were evaluated retrospectively.All of the cases underwent plain CT scan of head,2 cases of which underwent plain and con-trast-enhanced MRI scan.5 cases (5/6 )underwent upper abdominal plain and contrast-enhanced CT scan and 1 case under-went MRI examination.Results:All the cases had bilateral multiple lesions.The main CT features of metastatic neuroblasto-ma in craniofacial bone were vermiform destruction,subperiosteal vertical speculated high density areas in involved bones and slightly high density soft tissue mass with calcification.Two cases showed destruction in several craniofacial bones and soft tissue masses with calcification.The masses were showed iso-intensity on T1-weighted images,mildly high intensity on T2- weighted images.After administration of gadolinium contrast medium,obvious enhancement was assessed in soft tissue masses and meninges.Retroperitoneal masses with calcification and heterogeneous enhancement were assessed on abdominal CT scan of 5 cases,and a retroperitoneal mass was found on MRI.Conclusion:CT and MRI findings of metastatic neuroblas-toma in craniofacial bones have some characteristics,and are helpful for the diagnosis before surgery.
