Nematode infection: A rare mimic of acute appendicitis.

INTRODUCTION

Acute appendicitis is a common condition seen in all surgical units. One rare condition that can mimic acute appendicitis is a nematode infection of the bowel. There have been few reported cases of nematode infection within the appendix and none that have been accompanied by intra-operative pictures.

PRESENTATION OF CASE: A 16-year-old female presented with a 12h history of right iliac fossa pain and mild pyrexia. Bloods showed a neutrophilia and normal C-reactive protein. Laparoscopy was performed which revealed a non-inflamed appendix. The appendix was dissected and a live nematode was visualised exiting the base of the appendix. Anti-helminthics were given and the infection resolved.

DISCUSSION: Nematode infection is most commonly seen in Africa, Asia and South America. When seen within the United Kingdom (UK), it is seen most commonly within high-risk populations. Testing for these infections is not routine within the UK and when they are performed, the results take a considerable amount of time to return. These tests should be considered within high-risk populations so that unnecessary surgery can be avoided.

CONCLUSION

This case highlights the importance of considering rare causes of right iliac fossa pain including nematode infection in a young patient. The case highlights this by giving intra-operative pictures of live nematodes upon dissection of the appendix.
