However, 8%–20% of cases are idiopathic. We describe here the case of a 56-year-old Nigerian male who presented to the accident and emergency unit with features of acute intestinal obstruction. The findings at laparotomy were ileocolic intussusception without a lead point. A segment of the terminal ileum was nonviable. A right hemicolectomy with ileocolic anastomosis was performed, and the resulting specimen sent for histologic examination which confirmed no extra- or intraluminal lesion. Two years of postoperative evaluation was normal. This report further reiterates the fact that adult intussusception could be idiopathic (without a lead point) and could present as acute intestinal obstruction. Early recognition is necessary to facilitate timely intervention before the onset of gangrene, so as to improve prognosis.Keywords: atypical presentation, adult, ileocolic, intussusception
