Contemporary imaging of inguinal hernia and pain.

Inguinal hernias are the commonest type of hernia, and are frequently encountered by general, abdominal and musculoskeletal radiologists. Such hernias may cause discomfort or pain; but many other conditions may cause pain in a similar location, meaning it is not always straightforward to determine the underlying cause of a particular patient's symptoms. Although surgical fixation of hernia has high success rates with low recurrence, ongoing symptoms are common after apparently uncomplicated surgery. In particular, post-surgical chronic groin pain can be highly problematic in some patients. In this review, we highlight the relevant surgical and imaging anatomy, common modes of clinical presentation, contemporary surgical approaches to the repair of inguinal hernia, imaging techniques to diagnose such hernias in both unoperated and operated groins and mimics of hernia-related pain.
