Abstract
The vermiform appendix is considered the most mobile organ in the human body. Due to its various positions in the abdomen and pelvis, it may result in confusion in diagnosis to the surgeons when it becomes inflamed. Atypical locations of the appendix have been reported previously in the literature. We report an unusual location of the vermiform appendix in the right retro-psoas muscle space that was incidentally discovered in a male patient who was involved in a road traffic accident.
