Case of Spigelian hernia with incarcerated appendix

Spigelian hernias are uncommon lateral ventral wall hernias with a significant rate of incarceration; these hernias often produce nonspecific clinical signs and symptoms as well as elusive imaging findings. Although there are reported cases of incarcerated appendices within Spigelian hernias, this case specifically illustrates the diagnostic difficulty these hernias present to both surgeons and radiologists. Additionally, we discuss important anatomy, demographics and risk factors, clinical symptoms, imaging pitfalls and recommendations for repair based on a review of literature.
