Learning objectives To provide radiologists with a comprehensive understanding of the concept of internal hernia, with the aim of promoting its consideration in the differential diagnosis, as well as highlighting key radiological findings that facilitate its timely and accurate identification and classification.
Read more Background A narrative literature review was performed to collect current pertinent information on internal hernias, their subtypes, and key radiological features. Concurrently, representative cases were selected from the Radiology Department’s image archive at our hospital, focusing on confirmed internal hernia cases. Images were chosen for their educational value in illustrating identification and classification of various internal hernia types.
Read more Findings and procedure details An educational poster was created to summarise essential anatomical details and the aetiology of internal hernias. Congenital causes included enlargement of natural orifices and abnormalities due to intestinal malrotation, while acquired causes encompassed postoperative, post-traumatic, and iatrogenic origins.Below are some computed tomography signs whose identification is highly illustrative and aids in the diagnosis of internal hernia:– Whirlpool sign:The mesenteric vessels are seen twisting into a spiral configuration, indicating mesenteric torsion and an increased risk of intestinal ischaemia.– Mushroom sign:Occurs when...
Read more Conclusion This educational study offers a thorough overview of internal hernias, highlighting their anatomical basis, aetiological classification, and characteristic CT findings. By integrating literature review with illustrative cases from our institutional archive, the study aims to improve radiologists’ diagnostic accuracy of this frequently overlooked condition. Despite the main limitation being the absence of complementary imaging modalities such as MRI, the material provides valuable conceptual and visual resources for clinical practice. No funding was received for this study.
