    The study analyzed 15 cases of testicular embryonal rhabdomyosarcoma (ERMS) and 30 cases of testicular seminoma using enhanced CT imaging.

  • 2

    Significant differences in age, CT parameters, and laboratory indicators were found between ERMS and seminoma patients (p < 0.05).

  • 3

    Key CT features, such as the parallel relationship with the ipsilateral inguinal region and the vascular ball sign, helped differentiate ERMS from seminoma.

  • 4

    The ROC curve analysis showed an AUC of 0.961, indicating high sensitivity (86.7%) and specificity (96.7%) for distinguishing between the two neoplasms.

  • 5

    Postoperative disease progression was significantly higher in ERMS patients (66.67%) compared to seminoma patients (3.3%), highlighting ERMS's aggressive nature.
