Pancreas acinar cell cystadenoma in 52-year-old man.. A. Contrast-material enhanced, coronal reformatted multidetector CT image. Multiple hypodense cystic lesions are clearly seen in pancreas (arrows).. B-D. Coronal half-Fourier acquisition single-shot turbo spin-echo (HASTE) (B), axial precontrast (C) and postcontrast T1 weighted (D) MR images of pancreas. Nonenhancing cystic lesions are seen in pancreas (arrows).. E. Image of macroscopic specimen. Numerous cysts with thin translucent wall are seen in body and head of pancreas.. F, G. Numerous cystic spaces are diffusely distributed in pancreas tissue (F). Note small clusters of acinar cells forming acini that open into cyst lumens (G) (Hematoxylin & Eosin stain, original magnification, x 20 [F], 600 [G]).

CT scan (Fig. 1A). T1 weighted (W) images (Fig. 1B-D). The main pancreatic and extrahepatic bile ducts were normal on the T2W sequences. There was no discrete tumoral lesion, necrosis, calcification or hemorrhage observed on further examination of the pancreas (Fig. 1F). There were disseminated patchy acinar structures within some small and large cyst walls (Fig. 1E, F).
