Retroperitoneal Caecum and Looped Retroperitoneal Appendix - A Rare Cadaveric Finding

Caecum is the initial blind part of large intestine normally located in the right iliac fossa. It receives terminal part of ileum on its posteromedial wall. Vermiform appendix is attached to caecum below the attachment of ileum. Variations in the position of caecum have been reported which can be attributed to its development. However variations in the appendix are very rare and most often reported as a finding during surgery. This article reports a cadaveric finding where terminal ileum was opening on to the anterior aspect of caecum. The vermiform appendix was U-shaped and it was fixed to pelvic brim at the bend. This anatomical variation may be of interest to the surgeons operating in the region. A rare finding of appendix which is U shaped not reported so far.
