They appear dof high signal intensity on T1W/T1 fat sat with fluid-fluid levels giving T2 shading sign. No enhancement is seen on postcontrast sequences. Others small similar lesions are noted in the left pelvic wall within the rectus abdominis muscle (1.7 cm), at the semilunar line (Spigelian line) as well as multiple nodules in the peritoneal cavity.
