Sigmoid volvulus in an adolescent male patient

Sigmoid volvulus (SV) is a condition where sigmoid colon twists or torsions about its mesentery. This disorder is rare in infants and children[1]. It usually occurs in adults, after the age of 40, more commonly in males[2]. SV leads to intestinal obstruction, which is often acute in children, whereas in adults it may be subacute or progressive. As a result of intestinal obstruction, the most common symptoms include abdominal pain, distention, vomiting and, in chronic cases, constipation. In Europe, Australia and the United States, the incidence of SV is very low. Nevertheless, SV remains the leading cause of acute colon obstruction in developing countries[3]. The diagnosis is based on clinical and radiological findings and is more difficult to establish in children compared to adults[4], and a correct diagnosis can be easily missed or delayed[4]. We present a case report with exceptional quality CT images and 3D reconstructions.
