Title: Ultrasonic "double track" sign in hypertrophic pyloric stenosis. Author: Cohen HL, Schechter S, Mestel AL, Eaton DH, Haller JO. Journal: J Ultrasound Med; 1987 Mar; 6(3):139-43. PubMed ID: 3550137. Abstract: Ultrasound has been used in the diagnosis of hypertrophic pyloric stenosis since the first reports of its use with contact B mode scanners. Real-time imaging has allowed measurements of pyloric diameter, length, and muscle wall thickness. Wall thickness measurements taken with the pylorus in longitudinal (elongated) view improve diagnostic accuracy. Fluid aided real-time examination of 10 cases showed the ultrasound equivalent of the "double track" sign. This finding is the result of pyloric fluid compressed into smaller tracks as it is impinged upon circumferentially by the thickened circular muscle. This sign, previously seen in barium studies, although nonspecific, may prove to be a sensitive diagnostic criterion.[Abstract] [Full Text] [Related] [New Search]
