Neuroendocrine rectal tumour as a rare aetiology of adult recto-sigmoidal intussusception: case presentation and literature review
Oncol Clin Pract 2018;14(5):282-285.
Abstract
Intestinal intussusception is a frequent paediatric pathology, but adult cases are rare and do not have a specific
presentation. In most cases adult intestinal intussusception, regardless of its localisation, is caused by an endoluminal
tumour, which can be of multiple pathological types. We report a sigmoido-rectal intussusception in an adult in whom an adenoneuroendocrine tumour was identified as the lead point. This case is unique for the following reasons: (1) neuroendocrine tumours rarely involve the sigmoido-rectal segment of the gut, (2) clinical presentation with a recto-sigmoidal intussusception presented a diagnostic challenge.
