Pathophysiology[edit | edit source]

  • The Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly.
  • It is characterized by hypertrophy of the mucosal epithelium.
  • The thickened epithelium then invaginates into the interstices of a thickened muscularis.
  • It forms so-called Rokitansky-Aschoff sinuses.

Types[edit | edit source]

There are three forms of ADM: segmental, fundal and more rarely, diffuse
