Sonographic detection of an aneurysm of the gastroepiploic artery.

Gastroepiploic artery aneurysm (GEAA) is very rare.1 Furthermore, most GEAA cases are diagnosed after their rupture. We report a case of asymptomatic GEAA. The patient was a 61-year-old man. Sonography (US) revealed a 2-cm anechoic mass in the epigastrium near the anterior abdominal wall. Color Doppler US and contrast-enhanced US showed arterial flow within the mass leading to the diagnosisof visceral artery aneurysm. CT and angiography confirmed the diagnosis of right GEAA, and the aneurysm was treated successfully with embolization. Follow-up US 6 months later confirmed the absence of blood flow within the lesion. (c) 2009 Wiley Periodicals, Inc. J Clin Ultrasound, 2010.
