ABSTRACT
History A 78-year-old woman was transferred from the local nursing home complaining of abdominal pain and vomiting. She has been suffering from intermittent colicky abdominal pain for several years with no clear exacerbating or relieving factors. The pain comes on gradually, centred on the lower abdomen, and usually lasts a few hours before resolving spontaneously. It is often associated with nausea but never vomiting. She has been extensively investigated with computed tomography (CT) and a colonoscopy, but these were performed when the patient was asymptomatic and found no abnormality.
