I am suspicious that this hernia is in fact a femoral hernia as in the short axis image it is adjacent to the femoral vein and in the long axis it looks like it comes out from under the inguinal ligament and inguinal canal.
In a female patient this would be a common hernia.
I am going for femoral in this case given there images you have provided.
Remember all inguinal hernias have to pass anterior to the inguinal ligament and all femoral hernias have to pass deep to (posterior) to the inguinal ligament.
