Abstract

Objective: This study aims to clarify the frequency of renal parenchymal defects and deformations in each subtype of perirenal liposarcomas and to compare the differences between well-differentiated and non-well-differentiated types.

Methods: Patients with perirenal liposarcomas seen between July 2004 and June 2024 were included. Two radiologists blinded to the subtypes retrospectively evaluated CT or MR images for renal parenchymal defects and deformations. Frequencies of these findings were compared between well-differentiated versus non-well-differentiated types using the Fisher test.

Results: Forty-two patients (mean age: 66.3±11.5 y; 15 men) with perirenal liposarcomas were included. Renal parenchymal defects and deformations were observed in 0 (0%) and 1 (7.7%) of 13 well-differentiated, 5 (29.4%) and 6 (35.3%) of 17 dedifferentiated, 3 (37.5%) and 0 (0%) of 8 myxoid, and 1 (25.0%) and 1 (25.0%) of 4 pleomorphic types, respectively. Non-well-differentiated liposarcomas had higher frequencies of renal parenchymal defects and deformations compared with well-differentiated liposarcomas [9 of 29 (31.0%) vs. 0 of 13 (0%), P=0.038 and 7 of 29 (24.1%) vs. 1 of 13 (7.7%), P=0.398].

Conclusion: Renal parenchymal defects can be occasionally observed (31.0%) in non-well-differentiated perirenal liposarcomas unlike well-differentiated liposarcomas.

与高分化型不同,非高分化肾周脂肪肉瘤偶见肾实质缺损。
目的:本研究旨在明确肾周围脂肪肉瘤各亚型肾实质缺损和变形的发生率,并比较高分化型和非高分化型的差异。方法:选取2004年7月至2024年6月间发现的肾周脂肪肉瘤患者。两名不了解亚型的放射科医生回顾性评估了肾实质缺陷和变形的CT或MR图像。使用Fisher检验比较这些发现在高分化型和非高分化型之间的频率。结果:42例患者(平均年龄:66.3±11.5岁;包括15名男性)肾周脂肪肉瘤患者。13例高分化肾实质缺损和变形分别为0(0%)和1(7.7%),17例去分化肾实质缺损和变形分别为5(29.4%)和6(35.3%),8例粘液样肾实质缺损和变形分别为3(37.5%)和0(0%),4例多形型肾实质缺损和变形分别为1(25.0%)和1(25.0%)。非高分化脂肪肉瘤的肾实质缺损和变形发生率高于高分化脂肪肉瘤[29例中有9例(31.0%)比13例中有0例(0%),P=0.038; 29例中有7例(24.1%)比1例(7.7%),P=0.398]。结论:与高分化脂肪肉瘤不同,非高分化肾周脂肪肉瘤可偶见肾实质缺损(31.0%)。

期刊介绍: The mission of Journal of Computer Assisted Tomography is to showcase the latest clinical and research developments in CT, MR, and closely related diagnostic techniques. We encourage submission of both original research and review articles that have immediate or promissory clinical applications. Topics of special interest include: 1) functional MR and CT of the brain and body; 2) advanced/innovative MRI techniques (diffusion, perfusion, rapid scanning); and 3) advanced/innovative CT techniques (perfusion, multi-energy, dose-reduction, and processing).
