Inversion or intussusception of the appendix

Two cases of intussusception or inversion of the appendix are highlighted. One patient presented with chronic right iliac fossa pain and at laparoscopic surgery was noted to have a polypoid lesion at the appendiceal orifice opening into the caecum. The second Case was discovered at routine colonoscopy and thought to be a polypoid caecal tumour. In both cases the appendix had inverted and masqueraded as caecal lesions. Histological evaluation showed the entire circumference of the appendix inside of the appendix lumen simulating a telescoping phenomenon.
