At the body-tail of the pancreas, there are cystic multilocular lesions of about 8 cm, with numerous calcifications in the walls and septa. The most caudal portion of this lesion has microcystic appearance, with cysts in water content while the most cranial portion is constituted by cysts greater in protein content. The duct of Wirsung is not dilated. There are collateral circles near the spleen and stomach.
