Hepatic ultrasound images in B mode showing the presence of hyperechoic intrahepatic formations, outlining the path of the intrahepatic bile ducts (IHBD), some of which describe a discrete posterior shadow cone, while others produce a comet-tail artifact testifying of their cholesterolic character.

Ultrasound showed hyperechoic intrahepatic formations, outlining the course of the intrahepatic bile ducts (IHBD), some of them with a discrete posterior shadow cone, others with a comet-tail artifact proving their cholesterolic character (Fig. 1).
Axial sections of a Bili MRI in T2 (A), T1 (B and C) and 3D MRCPR (D) sequences showing intrahepatic bile duct (IHBD) microlithiasis in asignal, predominating at the level of segment V (arrows).

MRCPR (Magnetic resonance cholangiopancreatography) demonstrated IHBD microlithiasis in asignal on all the sequences, more marked in the segment V (Fig. 2), taking the appearance of an endoluminal defect (Fig. 3).
