摘要
目的：回顾性分析小儿神经母细胞瘤脑膜转移的影像表现，提高对本病的认识。方法：搜集19例神经母细胞瘤合并脑膜转移的患儿，男9例，女10例，均行MRI平扫检查，其中9例同时行MRI增强检查，4例行CT平扫。结果：小儿神经母细胞瘤脑膜转移多为硬脑膜型，MRI表现为颅骨内板下方结节状病灶或条带状脑膜增厚，T1WI多呈稍低或等信号，T2WI多呈等或稍高信号，增强扫描呈明显强化；CT表现为颅板下新月形或梭形略高密度灶。结论：小儿神经母细胞瘤脑膜转移的影像表现有一定的特征性，MRI增强检查可为临床诊断、治疗和评估预后提供重要的影像学依据。
Abstract
Objective: To describe and analyze imaging characteristics of meningeal metastases from neuroblastoma in pediatric patients. Methods: Nineteen cases with meningeal metastases from neuroblastoma were selected, 9 males and 10 females, underwent MRI scan examination, 9 of them underwent enhanced MRI scan, 4 of them underwent CT scan examination. Results: Meningeal metastases from neuroblastoma in children often involved the dura. MRI showed the nodular lesions or banded thickening meninges under the skull plate. T1WI showed slightly low or equal signal. T2WI showed equal or slightly high signal. Enhanced MRI scan showed obvious enhancement. CT scan showed crescent-shaped or shuttle-shaped slightly high density under the skull plate. Conclusion: The imaging findings of meningeal metastases from neuroblastoma in children have certain characteristics. Enhanced MRI examination can provide important imaging evidences for clinical diagnosis, treatment and prognosis assessment.
