European Radiolog: Have you seen primary renal sarcoma?

In 2018, kidney cancer accounted for 2.
2% of all malignant diseases in the world
.

The most common kidney cancer subtypes, such as clear cell or papillary renal cell carcinoma, were originated in renal epithelial cells

In 2018, kidney cancer accounted for 2.

For general kidney mass evaluation, cross-sectional imaging, such as computed tomography (CT) and magnetic resonance imaging (MRI), is the cornerstone of initial diagnosis and treatment planning

Recently, published in the E uropean the Radiology journal of a study to systematically evaluate the imaging features of renal sarcoma, and propose a method for accurately distinguish renal sarcoma sarcoma and non-renal tumors , accurate diagnosis and treatment assessment of renal sarcoma Provide a strong reference basis .
 

This study evaluated adult patients diagnosed with renal sarcoma from 1995 to 2018

Finally, 34 renal sarcomas were

MRI image of a 49-year-old male patient .
The left kidney cystic mass is 204 mm in diameter and accompanied by a downward movement of the kidney .
Tl WI (A) show moderate the center of the signal intensity (SI; star) and the lower edge of the SI nodule (arrow) .
T2 WI (B) shows a high-SI central cyst (star) and necrotic components (arrows) in the edges of the nodules (arrows) .

Enhanced T1 WI fat saturation imaging (C, D) confirmed that the edge of the nodule (arrow) was enhanced, there were necrotic components (arrow), and the upper pole of the left kidney appeared as a mass (arrow, D) .

Renal sarcoma is a rare renal interstitial tumor, often manifested as a large and complex kidney mass in young patients
