Purpose
Acinar cell cystadenoma (ACC) is an uncommon entity with unknown physiopathology described for the first time in 2002 (1-3).
Its diagnosis is based on pathological criteria: cystic lesion with epithelial lining of typical acinar cells without atypia (fig 1-2).
15 cases (8 of them multilocular) had been reported in litterature (1-7) but fully described pattern correlated with pathology was not reported.
Most of the time,
patients presented abdominal pain and preoperative diagnosis was branch duct intraductal papillary and mucinous neoplasia (BD-IPMN).
Unlike IPMN,
ACC seems to be a benign entity and no malignant transformation has been described so far.
Thus its recognition may impact the patient’s management strategy.
The aims of this study were 1.
to determine radiological criteria of ACC using radiological correlation with gross pathological features and 2.
to use those criteria to discriminate ACC from BD-IPMN.
