    Acute (spastic) or chonic-reoccuring abdominal complaints.  

     Pathomorphology or Pathophysiology of this disease :

    Short-term invaginations with spontaneous release is often seen in GI-infections.

    In case of no spontaneous devagination while performing ultrasound: a pathologic trigger for the invagination (lymph node in mesenterial lymphadenitis, Meckel diverticulum, small polipous tumors) should be suspected.  

     Radiological findings:

    Ultrasound 1 <- view Ultrasound 1

    Ultrasound 1: Bulls-eye structure (gut in gut) in the area of the small intestines. Often an echogenic mesenterium between the two walls of the invaginate can be seen.

    Dessucation is often very short.

    Ultrasound 2 <- view Ultrasound 2

    Ultrasound 2: Here too one sees a lymph node in the dessucated mesenterium.

    Ultrasound 3 <- view Ultrasound 3

    Ultrasound 3: small amount of ascites

    Ultrasound 4 <- view Ultrasound 4

    Ultrasound 4: See ultrasound 1

     Diagnosis confirmation:

    Surgery / Histo  

     Which DD would be also possible with the radiological findings:

    Intestinal wall lymphomas
    Purpura Schönlein Hennoch
    GvH-Reactions of the intestinal wall.  

     Course / Prognosis / Frequency / Other :

    Often, spontaneous devagination.
    In case of invaginate persistence: unknown.  

     Comments of the author about the case:

    Controversial discussion of a case, in which we monitored the invagination. The parents dismissed surgical intervention, since no clinical symptoms were seen.  

     First description / History:

    Laurell had already written about Peyer's plaques, the possible cause of the invaginates that he described.
