A Case Report of Acute Appendicitis caused by Enterobius Vermicularis

Background: Acute appendicitis is an acute inflammation of the vermiform appendix. It is most likely due to obstruction of the lumen of the appendix and rarely can be caused by parasites. For a long time, the association between parasitic infection of the appendix and appendectomy has been widely investigated.

Objective: To describe a rare case of Enterobious Vermicularis parasitic infection presenting as a standard appendicitis without any clinical indications of parasites. This study aims to highlight the importance of parasitic infections as a deferential diagnosis of a very common condition.

Methods: We present a case report of a 11-years old girl with acute appendicitis caused by parasites. There were no signs of parasitic infection: her eosinophils were at normal range; the CRP protein levels were normal. There were no clinical symptoms as well indicating that it was a parasitic infection of the appendinx. During the laparoscopy, in the appendix were found alive helminths from the species Enterobius Vermicularis which were supposed to be the origin of the inflammation.

Results: The results of this study indicate that Enterobious Vermicularis is a rare etiological cause of acute appendicitis. The presence of this parasite can lead to serious changes in the appendix ranging to life-threatening complications.

Conclusion: Parasites are still present inffections and may cause serious inflamation even without any clinical indications. Due to that parasitic infection should be considered in any differential diagnosis of a common appendicitis.
