    Abstract:
    This report discusses hypertrophic pyloric stenosis (HPS) and the current approach to diagnostic imaging in the vomiting infant. Signs and symptoms include dehydration and vigorous gastric peristalsis with vomitus. Palpation of an olive-shaped firm muscular tumor is pathognomonic of this condition. The radiographic signs of HPS are well known. Previously published criteria for the sonographic diagnosis of HPS are discussed, these include: measurements of pyloric length, diameter and muscle thickness. The thickened muscle is the most discriminated and accurate one. It was concluded that real-time ultrasound is a simple, and reliable method for the diagnosis of HPS and should be the initial imaging procedure.
