Abstract

Intestinal malrotation corresponds to an embryological developmental anomaly resulting from a defect in the rotation and fixation of the midgut around the axis of the mesenteric artery. It is diagnosed in 75-85% of cases during childhood, with an incidence between 0.0001% and 0.19%. A case is presented of a 22-year-old young adult with multiple episodes of pain that worsened over the course of a year, abdominal distension, vomiting of gastric contents, and occasional constipation. She visited various healthcare services and was diagnosed with gastritis due to H. pylori infection, received treatment, and showed partial improvement. Subsequently, she returned to the emergency services with symptoms of intestinal obstruction. Studies were conducted, including an IV contrast computed tomography (CT) scan, which showed the presence of a characteristic whirl sign, associated with abnormal rotation of the midgut around the superior mesenteric artery. Early recognition of the diagnosis of intestinal malrotation in adults is important because its occurrence is rare, which necessitates the use of diagnostic tools such as imaging studies for an appropriate surgical intervention, which is the cornerstone for improving the prognosis of these patients.
