Radiological studies play a crucial role in the evaluation of patients with biliary duct obstruction, allowing for the guidance of clinical diagnosis towards a malignant or stone-induced etiology through the recognition of relevant imaging features, which must be continuously revisited given their prognostic significance. This article aims to emphasize the importance of recognizing crucial imaging aspects of malignant and stone-induced biliary obstruction.

Keywords: Malignant biliary obstruction, Choledocholithiasis, Dilated bile ducts, Magnetic resonance, Multidetector computed tomography

Core Tip: Recognizing the radiological aspects of biliary obstruction is crucial for distinguishing between lithiasis and malignant origins, thereby facilitating the diagnosis and management of this pathology.
