摘要


中胚層腎瘤,或者被稱為胎兒間葉缺陷瘤或是平滑肌缺陷瘤,主要發現在幼兒時期。在孩童時期是個少見的腫瘤,佔所有孩童腎臟腫瘤約佔百分之五的比例。在成年人更為罕見。根據過去的文獻,到西元1999年只有23個病例報導。我們報告一位成年中胚層腎瘤病例。在超音波下顯示非均勻性超音波密度。未打顯影劑的電腦斷層表現為幾乎均勻的腫瘤。打顯影劑之後電腦斷層則是呈現不均勻的增強。

Mesoblastic nephroma, also known as fetal mesenchymal hamartoma or leiomyomatous hamartoma, is predominantly seen in infancy. It is a rare tumor in children, only accounts for about 5% of all renal tumors in childhood. In adulthood, it's even rarer. According to the literature, there were only 23 cases of adult mesoblastic nephroma were reported till 1999. Herein we present an adult with mesoblastic nephroma, which shows heterogenous echogenesity in abdominal sonography. Computed tomography revealed almost homogeneous attenuation on unenhanced series and enhanced heterogeneity after intravenous contrast medium injection.
