Acinar cell carcinoma (ACC) is a rare pancreatic exocrine neoplasm characterized by a huge, exophytic well-circumscribed hypovascular mass. There has been several reports describing intraductal and papillary variant of ACC and they showed different radiologic features from usual ACC. We present histologically confirmed cases of intraductal and papillary variant of ACC that had been found in two patients, who underwent CT and MRI. This report provides CT and MRI features of intraductal and papillary variant of ACC in pancreas with pathologic correlation after surgical excision.
