Background: Various kinds of foreign bodies causing appendicitis have been reported. However, a needle located in the appendix is very rare, especially in adults.
Case presentation: We report an unusual case of a twenty years old man who had ingested a needle ten days before and presented with signs and symptoms of acute abdomen. Abdominal CT scan revealed acute appandisitis so the patient was successfully treated with laparoscopic surgical intervention.
Conclusion: In cases of foreign body in the gastrointestinal tract which can not be removed endoscopically, and followed up with conservative treatment, the emergence of non-specific symptoms may be the early symptoms of acute abdomen.
