  • Figure 1
    Axial T1 and T2-weighted MR
     

    MR images show a thickened gallbladder wall and intramural cavities, which are hypointense on the T1- weighted images and hyperintense on the T2-weighted images (Rokitansky-Aschoff sinuses).

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

    This thickening is located in the fundus and extends to the body causing important luminal stenosis.

    The Rokitansky-Aschoff sinuses are markedly hyperintense T2-WI aligned spots forming the “string of beads sign” or “pearl necklace sign”.
