Reviewer's report:  
 
The authors present a case of metastasis to the spermatic cord and testis from advanced gastric 
cancer. Imaging revealed an irregular elongated mass and a round mass along right inguinal 
canal, and a diagnosis of metastasis from gastric cancer was made aft er US -guided biopsy. The 
case is simply interesting, particularly for the metastatic lymph node at the aortocaval space 
implied the metastasis pathway. However, the possible diagnosis of primary sarcoma on the 
images should not be excluded only by the inci dence is very rare. To mention more about the 
components and signal intensities of the lesions along right inguinal canal would be helpful to 
exclude primary sarcoma in inguinal canal, such as liposarcoma.
