Hypertrophic Pyloric Stenosis Mr Findings

Infantile hypertrophic pyloric stenosis (IHPS) is a condition affecting young infants, in which the antropyloric portion of the stomach becomes abnormally thickened and manifests as obstruction to gastric emptying. The clinical diagnosis hinges on palpation of the thickened pylorus, or “olive.” Abdominal palpation is accurate but not always successful, depending on factors such as the experience of the examiner, the presence of gastric distention, and a calm infant. In patients in whom clinical examination is unsuccessful, modern imaging techniques are highly accurate in facilitating the diagnosis. The radiologist, therefore, plays a key role in the initial care of these infants and the appropriate surgical referral. Fluoroscopy, gray scale ultrasonography (US) and Doppler US could be used in the diagnosis of IHPS. There are a lot of studies in the literature performed with these modalities (1-5). The purpose of this study is to show and describe (magnetic resonance imaging) MRI findings in IHPS.
