Role of Endoscopic Ultrasonography in Differential Diagnosis of Pancreatic Cystic Lesions

Abstract

Pancreatic cystic lesions (PCLs) are being identified increasingly because of recent advancements in abdominal imaging technologies, presenting a number of challenges in clinical practice. Although most PCLs are benign, some carry a significant risk of malignant degeneration. Accurate diagnosis of PCLs is important for proper management and follow-up. Endoscopic ultrasound (EUS) is useful for the characterization of PCLs with high sensitivity and accuracy. Additional information can be obtained using EUS for indeterminate lesions on computed tomography or magnetic resonance imaging. In this review, we introduce the relevant EUS findings for the diagnosis of relatively common PCLs.
