Intestinal malformations are common disorders in newborn and favorable outcomes have been reported for such conditions. Although, if the patient is treated in a not experienced center, misinterpretation of the clinical and radiological findings may lead to errors in treatment and possible complications in adulthood. We report a case of a congenital megaduodenum which was misinterpreted as an intestinal malrotation resulting in late complications. The patient underwent a successful surgical resection of the duodenum with improvement of his clinical symptoms and nutritional status. This case report emphasizes the importance of considering megaduodenum in the differential diagnosis of patients with feeding impairment, even during adulthood. Early diagnosis and treatment may improve patients' outcome and reduce morbidity.
