Learning objectives
To present the radiological findings associated with common abdominal hernia subtypes.
To recognise complications of abdominal wall hernias on CT.
Background
A hernia may be defined as an abnormal bulge, protrusion or projection of an organ, or part of an organ, through the wall of a cavity within which it is usually contained. Abdominal wall hernias are commonly encountered in clinical practice, with a prevalence of 4% for individuals aged 45 years and older. They are a common imaging finding in the abdomen and may be complicated by strangulation, incarceration, or trauma. Due to the risk of developing complications, most abdominal wall hernias are surgically repaired,...
Findings and procedure details
Inguinal Hernia
Inguinal hernias can be classified as direct or indirect based on their relationship to the inferior epigastric vessels (Fig 1, 2). Direct inguinal hernias are medial to and indirect inguinal herniasare lateral to the inferior epigastric vessels. They can occur in children and adults but are more common in males, regardless of age. Indirect inguinal hernias are the most common and are caused by the protrusion of peritoneal content through a patent internal inguinal ring. In males, the hernia extends along the spermatic...
Conclusion
Abdominal wall hernias are a common clinical presentation. Along with a clinicalhistory and examination, imaging aids in the accurate diagnosis. CT imaging provides excellent anatomic delineation and allows for optimal treatment planning.
