To study the value of the CT scan in the diagnosis of internal herniation and to evaluate its performance comparing its features to preoperative data.

We report 3 cases of patients with internal hernias (two men and one woman whose age is 23, 45 and 60 years) hospitalised in emergency for a small bowel obstruction. There were no previous abdominal surgeries or trauma, The three patients underwent CT scan. Signs of tranmesenteric hernias and hernia through the falciform ligament were diagnosed preoperatively and confirmed at laparotomy.

The internal hernia is rare cause of small bowel obstruction. The CT scan is an important way to make diagnosis and to choose the surgical strategy.
