We describe the case of a 73-year-old woman with a high body mass index and a virgin abdomen who presented with a 5-day history of abdominal pain, emesis and confusion on admission. Inflammatory markers and renal function were significantly deranged. CT of the abdomen and pelvis demonstrated a clear transition point and faecalisation of the small bowel proximal to the obstruction. It was suggested that the patient may have ingested a foreign object. A collateral history was obtained, making this less likely and confirmed an acute cognitive impairment. She was optimised following multidisciplinary discussion preoperatively. Thereafter, the patient underwent a laparotomy, where a hard, mobile mass was identified in the jejunum. This was diagnosed as an enterolith of dimensions 62×38×32 mm secondary to a duodenal diverticulum. She improved postoperatively with complete resolution of her confusion and renal function. She was discharged on day 14 of admission.
