INTRODUCTION: Spigelian hernias are rare hernias of the anterior abdominal wall named after Adrian van den Spiegel, the anatomist who first described them in the 16th century. They represent around 2% of all hernias. PRESENTATION OF CASE: We present an 83-year-old female with one week history of a painful right iliac fossa swelling, her examination revealed a tender lump with no cough impulse and non-reducible and her computed tomography (CT) scan showed a mass anterior to ileocaecal valve suggestive of a caecal volvulus. Intra-operative the finding was a Spigelian hernia containing an appendicular abscess and an appendicolith. DISCUSSION: The diagnosis of Spigelian hernias represents a challenge for the surgeons principally due to their rarity but also due to their anatomy and the variety of their contents. Searching the literature we found many different intra-abdominal structures presenting within a Spigelian hernia but we did not encounter a case similar to this. CONCLUSION: Clinicians need to be aware of these hernias when dealing with lower abdominal swellings and have a high index of suspicion even in the presence of negative clinical and CT findings.
