"The absence of communication with the inguinal canal, reducibility, and bowel content/peristalsis help to differentiate from an inguinal hernia or lipoma, although a strangulated or incarcerated hernia may be aperistaltic and irreducible 4. The presence of a poorly circumscribed mass, heterogenous echotexture, or vascularity, should raise the possibility of liposarcoma 4,5."
"While sometimes an incidental finding, this modality may also be used to help evaluate lesions with unclear or concerning characteristics on ultrasound 5,6. Characteristic homogenous, circumscribed fat attenuation, without inguinal canal communication or contrast enhancement, may be appreciated 5."
