title: [Mutiple-slice spiral CT diagnosis of atypical intraabdominal hernia].
abstract: OBJECTIVE
  To discuss the value of multiple-slice spiral CT diagnosis of atypical intraabdominal hernia.
  
  
  METHODS
  The clinical and CT findings of 16 cases of atypical intraabdominal hernia confirmed surgically were retrospectively analysed.
  
  
  RESULTS
  In all the 16 cases, the contents of hernia were small bowels and the mesentery. Nine cases were caused by the adhesion after abdominal operations or infection, 6 by the mesenteric foramen, and 1 by the gap of pelvic peritoneum. The main CT findings were as follows:(1)the obstructed small bowels gathered abnormally and showed cluster shape(9 cases); the walls of the bowels thickened with edema and showed "target" sign with exudate in the neighboring spaces(5 cases); other part of the abdominal cavity became empty for lack of small bowels(4 cases).(2) Abnormal arrangement of the branches of mesenteric vessel, which appeared gathered or pulled or rigid and displacement of the main branches to left or right(12 cases). Thickened mesenteric vessel (4 cases): torsion of mesentery with "whirlpool" sign (3 cases). (3) With the help of multiplanar reformation, 5 cases showed the evidence of hernia rings. In the ring area, there were gathered or pulled or rigid and radiating mesenteric vessel and the dilated or effusion bowels in cluster arrangement forming "parachute" and "bundle of balloons" sign.
  
  
  CONCLUSIONS
  CT manifestations of atypical intraabdominal hernia has some specific characteristics, which is of important value for clinical diagnosis and treatment.
