Background
To provide a pictorial review of internal hernias. To show different imaging findings of the internal hernias. Target audience: Radiology residents, abdominal radiology fellows.
Educational Goals / Teaching Points
Review the imaging common findings of internal hernias in MDTC. Describe the most frequent variably type of internal hernias.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
The internal hernias diagnosis is a challenge for the radiologist, because of their decreased frequency as well as because of their similarity to other conditions that have similar clinical and imaging presentations (volvulus, bridle). These are defined as the protrusion of an abdominal viscera through an orifice within the abdominal cavity, which can be anatomical or acquired. It is considered a surgical emergency. The present work includes a review of the common tomographic characteristics of internal hernias, including the encapsulation of intestinal loops in an abnormal location, agglomeration of loops in a hernial sac, signs of obstruction with segmental dilatation and variation in the arrangement of the mesenteric vessels. This exhibit includes a brief compilation of frequent presentations.
Conclusion
MDCT represents a fundamental element in the diagnosis of this pathology, in association with MPR and the possibility of injecting IV contrast increases the possibility of a correct diagnosis.
