The plan radiographs and computed tomography (CT) scans of 12 children with abdominal neuroblastoma were reviewed to evaluate the incidence and shape of calcification in the tumor. Calcifications were detected in 7 cases by plain radiographs and in 10 by CT. Small dotted and thin ring calcifications were better shown by CT. Ring calcification does not appear to be as rare as has been reported. It is emphasized that all ring calcifications in the vicinity of adrenal glands are not benign.
回顾了12例腹部神经母细胞瘤患儿的平片和计算机断层扫描（CT），以评估肿瘤内钙化的发生率和形态。平片检查发现7例有钙化，CT检查发现10例有钙化。小斑点状和细环状钙化在CT上显示更佳。环状钙化似乎并不像所报道的那样罕见。需要强调的是，肾上腺附近的所有环状钙化并非都是良性的。
