    Ultrasonography
     

    45° oblique scan showing the porta hepatis. A round hypoechoic cyst-like lesion is visible above the portal vein and the common hepatic duct.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Cysts;

    45° oblique scan detailing the cyst-like lesion: it appears unilocular and it shows thin walls, without internal septa, mural nodules or papillary projections.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Cysts;

    45° oblique scan showing an apparent communication with the common hepatic duct and the maximum diameters of the lesion (10.5 x 11.4 mm).

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Colour-Doppler sonogram of the same lesion showing the absence of proper vascularization.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Cysts;

    T1-weighted GRE sequence in the axial plane showing a round-shaped lesion with a very high signal intensity near the hepatic hilum. The maximum diameter measures 15.6 mm.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    T2-weighted TSE sequence in the axial plane presenting the same lesion with mild homogeneous hyperintensity and thin walls. No mural node or papillary projection is visible.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    T2-weighted SPIR sequence in the axial plane revealing the high signal intensity of the lesion, suggesting fluid content.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Fast GRE "THRIVE" sequence in the axial plane excluding the presence of adipous content within the lesion.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Fast GRE "THRIVE" sequence in the axial plane acquired in the arterial phase. The lesion appears less hyperintense for the "rescaling" phenomenon.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Fast GRE "THRIVE" sequence in the axial plane acquired in the portal-venous phase. The lesion appears even less hyperintense.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Fast GRE "THRIVE" sequence in the axial plane acquired in the equilibrium phase.

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Ballanced sequence in the coronal plane. Here the lesion appears in the hepatic hilum (arrow).

     
    Area of Interest: Biliary Tract / Gallbladder; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Cysts;

    Fast GRE "THRIVE" sequence in the portal-venous phase. Multiplanar reconstruction shows the lesion. The arrow indicate the confluence between the left and the right hepatic ducts in the common hepatic duct.
