目的:分析小儿神经母细胞瘤(NBT)硬脑膜外转移的CT表现特点,提高对本病的认识。材料和方法:回顾性分析3例经活检病理或临床、影像学及尿香草扁桃酸(VMA)检查证实为NBT的CT表现特点,均行头颅平扫,其中1例行MRI平扫,2例加胸部CT扫描。结果:肿块位于内板下,常双侧多处发生,以稍高密度为主,部分呈等密度,局限时呈梭形,较广时呈新月形,邻近骨质呈花边状破坏,侵入皮下可形成软组织肿块。2例肿块向眶内扩展,蝶骨小翼及眼眶外壁破坏,眼球向外突出。结论:NBT硬脑膜外转移CT表现有一定的特征性,CT检查可为临床治疗提供重要的影像学依据。
Objective: To analyze the features of CT manifestations of pediatric neuroblastoma (NBT) and to improve the understanding of this disease. MATERIALS AND METHODS: Three cases of CT manifestations confirmed by biopsy or clinical, radiological and urinary vanillic acid (VMA) examination were retrospectively analyzed. All patients underwent cranial scan, including 1 case underwent MRI scan and 2 cases Plus chest CT scan. Results: The lumps were located under the inner plate and often occurred at multiple sides, with a little higher density, some of them were of equal density, fusiform when confined and crescent with a wider area. The adjacent bone was lace-like and invaded Subcutaneous soft tissue mass can form. 2 cases of mass expansion to the orbit, sphenoid wing and the destruction of the orbital wall, prominent eyeball outward. Conclusion: NBT has the characteristic of dura mater transfer CT, CT examination can provide important imaging evidence for clinical treatment.
