Calcified Cystic Lesion of the Pancreas.

Pancreatic cystic lesion is a relatively uncommon condition with an estimated prevalence of 2 % in the general population. In the past two decades, there has been a dramatic increase in the prevalence of pancreatic cystic lesions because of the widespread use of high-resolution imaging, as well as the aging of the population. Pancreatic cystic lesions cover a wide spectrum of pathology and can range from obviously benign to borderline malignant potential lesions to overt malignancy. Though the presence of mural nodules, septa-like structures, or calcification on imaging examination contributes to the differential diagnosis, preoperatively determining the biological nature of these cystic lesions is sometimes challenging. In this paper, we report a rare case of pancreatic cystic lesion with an egg-shell like calcification. Complete resection was performed and histological examination confirmed the diagnosis of calcified pancreatic pseudocyst.
