A Rare Case of Small Bowel Intussusception Secondary to Angiomyxoma With Concurrent Ovarian Cystadenofibroma.

Abstract

Adult intussusception is an uncommon condition that constitutes a small percentage of cases of bowel obstruction in adults. Unlike its paediatric counterpart, it is often linked to an underlying pathology, necessitating surgical interventions for diagnosis and treatment. This report discusses a case involving a 54-year-old woman who presented with symptoms of small bowel obstruction, including abdominal pain, nausea, and constipation, along with a one-month history of weight loss. Imaging revealed small bowel intussusception and an abnormal pelvic mass. Surgical intervention confirmed an ileo-ileal intussusception with an intraluminal mass as the lead point and a concurrent ovarian mass. The histopathological analysis identified the lead point as a benign small bowel angiomyxoma alongside a benign ovarian cystadenofibroma. The patient recovered well following laparoscopic reduction of the intussusception, bowel resection, and bilateral salpingo-oophorectomy. This case highlights the diagnostic challenges posed by adult intussusception due to its nonspecific presentation and underscores the importance of imaging, surgical management, and multidisciplinary collaboration. The rare finding of a small bowel angiomyxoma as a lead point emphasises the diverse aetiology of this condition.
