title: [Local tumefaction of the gallbladder wall due to pancreatic heterotopia].
abstract: A 38-year-old woman was examined because of vague abdominal symptoms. Cholecystography and US studies demonstrated a lobulated tumor, 14 mm in length, with a homogeneous structure, sharp limits, adjacent to the posterior wall of the gallbladder and producing no acoustic shadow. Pathological examination demonstrated subserosal pancreatic heteropia. More than 22 different kinds of focal lesions affecting the gallbladder wall have been described. Unfortunately, no clinical or US criteria allow a definite diagnosis. Only the size makes a difference: more than 94% of the adenomas measuring less than 10 mm are benign whereas 88% of the malignant lesions are over 10 mm. Considering the absence of specific criteria, surgical removal is therefore indicated for lesions over 10 mm.
