Symptomatic Diffuse Adenomyomatosis of the Gallbladder–Report of a Rare Case

Adenomyomatosis of the gallbladder is a benign and degenerative condition of the gallbladder, characterized by proliferation of the mucosa of the gallbladder wall, forming invaginations and diverticula, penetrating a thickened muscular layer: the so-called Rokitansky-Aschoff sinuses (RAS). Most of the patients with adenomyomatosis remain asymptomatic. Hence adenomyomatosis is usually an incidental finding, either on ultrasonography performed for the detection of stones or by histologic examination of surgical gallbladder specimens. We report a case of symptomatic diffuse adenomyomatosis of the gallbladder. Clinical findings, etiology, diagnosis and therapy are discussed.
