Inguinal US showing a 2.9 x  1.2 cm solid-cystic mass in the right inguinal region (arrow head). The spermatic cord was swollen with a high echo. (A) Long-axis view. (B) Color Droppler mode showing blood flow signals within the mass. (C) Short-axis view.

No obvious hernia contents or enlarged lymph nodes were observed when abdominal pressure increased (Figure 1). The timeline of the presented case is summarized in Supplementary Figure S1.
Contrast-enhanced CT (axial plane) revealing a 2.3 x  1.3 cm heterogeneous and an avidly enhanced mass with a soft-tissue density (arrowhead) in the right inguinal region. Perilesional effusions were observed. (A) Non-contrast phase. (B) Arterial phase of the contrast. (C) Venous phase of the contrast.

A 2.3 x 1.3 cm heterogeneously enhanced mass with soft tissue density was seen inside the right inguinal canal (Figure 2).
MRI imaging (axial plane) showing a 2.3 x  1.3 cm oval mass in the right inguinal region, with perilesional effusions and edema. (A) T1-weighted imaging showing that the lesion was hypointense (arrowhead). (B) T2-weighted imaging showing that the mass (arrowhead) was hyperintense. (C) The mass was hyperintense (arrowhead) in diffusion-weighted imaging (DWI).
