Abstract

Acinar cystic transformation of the pancreas is also known as acinar cell cystadenoma (ACC), and this is an extremely rare benign lesion that was first described in April 2002. We report here on a case of a previously asymptomatic patient with pancreatic ACC and this was diagnosed by computed tomography (CT) and magnetic resonance imaging (MRI). To the best of our knowledge, there is no previous report concerning the CT or MRI features of ACC in the medical literature. We present here the CT, MRI and pathological findings of pancreatic ACC.

  Fig. 1 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, × 20 [F], 600 [G]).
