Intestinal malrotation is usually diagnosed in the first year of life; however; the symptoms can intensify only at an older age, causing diagnostic problems. The patients may suffer from different complaints and have a diagnosis completely unrelated to existing intestinal malrotation. We present a case of an 11-year-old female with malnutrition and acute renal failure incidents who had the intestinal malrotation diagnosed with ultrasound examination. The final diagnosis was confirmed with upper and lower gastrointestinal series and later during surgery.
