Materials and Methods The plain and enhanced CT findings of 9 patients with AACs proved pathologically were analyzed retrospectively. Results The main image ifndings of the patients were as follows:①the pancreas grew with exophytic dilatability;②they tended to be large (average diameter was 4.7 cm), with round or oval shape; ③ the lesions showed hypodense on enhanced scan and the solid areas showed slight enhancement in the arterial phase compared with normal pancreas;④most lesions had uniform or partial thin enhanced ring;⑤most lesions demonstrated cystic or necrotic;⑥few had pancreatic/biliary ductal dilatation and peripancreatic involvement;⑦few showed internal calciifcation or intratumoral hemorrhage. Conclusion Plain CT scan and enhanced scan are signiifcant in locating and differentiating acinar cell carcinoma of the pancreas.
