Review of internal hernia as a diagnostic challenge and problem:
Internal hernias are not common pathologies, but it should be in differential diagnosis of any case presented with intestinal obstruction symptoms. We should always bear in mind that ischemia and strangulation of the affected loops could be arise.
Imaging modality such as MDCT plays an important role in the diagnosis of internal hernias, particularly high resolution Multiplanar Reformatted images (MPR).
MDCT is usually the first line in imaging diagnostic techniques.
The main purpose of this paper is to describe the characteristics of anatomical location and CT findings of important types of abdominal and pelvic internal hernias such as paraduodenal, foramen Winslow, pericecal, sigmoid-mesocolon, and supravesical hernias.
In this article we review CT findings of 15 cases with different types of internal abdominal hernias and illustrate the imaging findings of internal hernias, focusing on CT imaging features.
We mentioned that it is very important for radiologists to be familiar with various types of internal hernias, to know their CT imaging features and accordingly prompt to make an accurate diagnosis.
