Acute appendicitis within a recurrent inguinal hernia presenting as epididymo-orchitis

We report the first case of appendicitis within a recurrent inguinal hernia, more unique in its presentation as epididymo-orchitis. A 61-year old male presented with right testicular pain, erythematous scrotum and raised inflammatory markers. He previously had recurrent left epididymo-orchitis and right inguinal hernia repair. A diagnosis of epididymo-orchitis was made but CT was performed which diagnosed acute appendicitis within a recurrent inguinal hernia entering the scrotum. This was confirmed intra-operatively with a distal inflamed appendix segment passing beyond the medial border of the exposed mesh. Correct pre-operative CT diagnosis requires high index of suspicion even with innocuous testicular symptoms. CT reduces misdiagnosis which is associated with significant morbidity, and also aids in planning surgical approach. The only other case of acute appendicitis presenting with testicular symptoms was diagnosed only during scrotal exploration necessitating further laparotomy. The appendix entrapment beyond the mesh could suggest an alternative aetiology of mesh-related appendicitis.
