We present a case of an unusually large, circumferential tubulovillous adenoma involving the terminal ileum and the caecum with ileocaecal valve consumption, presenting as intussusception in an otherwise healthy 90-year-old woman. The patient presented with several months of chronic symptoms of weight loss and diarrhoea. Clinical examination revealed a right-sided mass. Investigations revealed a large right-sided lesion suspicious of intussusception. The patient underwent a right-sided hemicolectomy where the intussusception was resected. Histology of the resected mass revealed a tubulovillous adenoma with focal invasive adenocarcinoma.

Contributors EM wrote the case report with help from PM and FK. EM assisted in ensuring the patient’s procedure went ahead as planned—there were several obstacles but managed to get it done at scheduled time. EM gathered all the necessary data and wrote out the initial draft of the report. PM performed the hemicolectomy and edited the surgical section of the case report. FK analysed the resected specimen and provided all of the histology input. EM and FK wrote the bulk of the case report—EM did much of the initial drafting and FK did most of the editing. PM provided very useful input on the direction and focus of the report.
