儿童肾母细胞瘤的CT诊断价值探讨(附66例分析)

An Assessment of CT Diagnosis in Nephroblastoma of Child

目的:主要探讨CT对儿童肾母细胞瘤诊断价值。方法:分析经临床和病理证实的66例儿童肾母细胞瘤的CT表现,并与手术和病理进行观察。结果:66例均起自于肾皮质,呈膨胀性生长。肾上极43例,肾体部14例,下极9例。实质性45例(68%),囊实性16例(24%),囊性5例(8%)。58例呈球形或椭圆形,其中56例包膜完整,边界清楚,2例不同程度的包膜破坏,8例形态不规则。均有不同程度突破肾包膜,肿瘤边界不清。结论:CT是目前诊断肾母细胞瘤的首选检查方法,它对肿瘤的定位、定性均有很大的帮助。

Objective： To determine the values of CT diagnosis and difference in nephroblastoma of child. Methods：CT data of 66 children with nephroblastoma to have been confirmed by clinic and pathology were reviewed retrospectively, according to the tumor＇s variables of the distribution and size, the morphology and CT attenuation. Results：All tumors originated from the renal cortex with the right kidney 37 cases and the left 29. These tumors are larger than 4.5cm in size, only ten cases encroach to the renal capsule. The tumor usually manifested as three types of attenuation patterns： solid （68%）, cystic - and - solid （24%）, cystic （8%）. Calcification could be observed in six cases. After enhancement, the parenchyma component of tumor was intensively enhanced; whereas the cyst and necrosis components not enhanced. Conclusions： CT is the best imaging checkups for the nephroblastoma, which can accurately show feature of the tumor, including size and distribution, clinical staging, and prognosis.
