Abstract

Visceral artery aneurysms have a potential possibility of rupture with life-threatening hemorrhage, and prompt detection and optimal treatment are required clinically. Actually, abdominal ultrasound plays a major role in detection of visceral artery aneurysms. Besides, the administration of contrast agents can highly improve the characterization of the lesion. Herein, we present two cases of giant peripancreatic artery aneurysm with emphasis on contrast-enhanced ultrasound (CEUS). Case 1 was a 54-year-old asymptomatic man who was diagnosed with a 12.1 cm × 5.2 cm splenic artery aneurysm in the absence of a clear etiologic factor. Case 2 was a 37-year-old man with a 6.3 cm × 5.3 cm pancreaticoduodenal artery pseudoaneurysm associated with chronic pancreatitis. Both diagnoses were confirmed by contrast-enhanced computer tomography (CECT) and digital subtracted angiography (DSA). Transcatheter embolization occlusion using coiling was successfully performed for both cases. Postoperative computed tomography angiography (CTA) showed complete occlusion. It is suggested that CEUS seems to be a promising diagnostic option and contributes to preoperative treatment planning for patients with peripancreatic artery aneurysm.
