Objective:To study the clinical and CT manifestations of internal hernia.Methods:The clinical and('T findings of 8 patients with surgery proved internal hernia were retrospectively reviewed.Results:Of the 8 patients,there were 3 patients with paraduodenal hernia(accurate diagnosis was obtained before surgery in 2 patients and one was misdiag- nosed as intestinal volvulus)and 5 patients with transmesenteric hernia(4 patients had history of previous abdominal sur- gery).The CT findings in common were small bowel obstruction,abnormal arrangement of small bowel,stretch,displace- ment,assembling and dilation of mesenteric vessels;displacement of other bowel segments.Sac-like dilation with disarrayed bowel located between stomach and pancreas or behind pancreatic tail could be revealed in left-side paraduodenal hernia, whereas dilated bowel located at the position of duodenal loop accompanied with disordered mesentery vessels could be re- vealed in right-side paraduodenal hernia.Small bowel disarrangement and lack of overlying omental fat,central displacement of colon could be seen in transmesenteric hernia and frequently complicated by small bowel obstruction or strangulation. Conclusion:Characteristic CT findings could be assessed in internal hernia,which was helpful in making a correct diagnosis in most of the patients.
