Computed tomography provides a graphic picture of dural involvement due to metastatic neuroblastoma. These metastases occur along the external surface of the dura and cause further separation of the brain parenchyma from the bony calvarium. The dural metastases are continuous with subcutaneous deposits via the separated sutures. Sutural separation is nonuniform, and the sutural margins are indistinct due to bony involvement. The lytic bony metastases may produce localized calvarial thickening that may have a sunburst appearance.
计算机断层扫描可提供转移性神经母细胞瘤所致硬脑膜受累的图像。这些转移瘤沿硬脑膜外表面发生，导致脑实质与颅骨进一步分离。硬脑膜转移瘤通过分离的缝线与皮下沉积物相连。缝线分离不均匀，由于骨质受累，缝线边缘不清晰。溶骨性骨转移瘤可导致局部颅骨增厚，可能呈日光放射状外观。
