title: Sonographic appearance of the Angelchik prosthesis.
abstract: The Angelchik prosthesis is a silicone-filled, doughnut-shaped device used for the surgical treatment of gastroesophageal reflux. This device appears on sonograms as a C-shaped, hypoechoic structure with nonspecific Doppler waveforms. Because the Angelchik prosthesis is rarely used anymore, recently trained sonographers and radiologists may misinterpret this sonolucent appearance as an unusual vascular lesion. We report a case of an Angelchik prosthesis that was incidentally noted at the gastroesophageal junction on a routine abdominal sonographic examination.
