Abstract: Objective To investigate the characteristics and diagnostic value of multislice spiral CT (MSCT) of intestinal lipomas causing intussusception.Methods The MSCT findings of 25 cases with intestinal lipomas causing intussusception were retrospectively analyzed,the tumor location,size,shape,density,enhancement patterns and shape and length of intussusception were also observed retrospectively.Results Tumors were 1.2-6.5 cm in diameter,round or oval in shape (n =18),irregular shape (n =4),tubular shape (n =3) with uniform density (n =19),or uneven density (n =6).Under CT enhancement tumor capsule was moderately intensified.Intussusception included ileum-ileum type (n =7),jejunum-jejunum type (n =5),jejunum-ileum type (n =2),ileum-colon type (n =4),and colon-colon type (n =7).Intussusception was 5.0-5l.0 cm in length;presenting as concentric circles (n =12),round target sign (n =7),orbanana (n =6).Conclusion Intestinal liporna complicating secondary intussusception has definite MSCT characteristics which can help establish diagnosis.
