A mucinous cystic neoplasm (MCNs) of the pancreas is an uncommon tumor that occurs mostly in females and are potentially sex hormone-sensitive. However, a MCN occurring during pregnancy is quite rare. A 25-year-old woman in the 35 week of gestation was referred to us because of a left flank pain. After unsuccessful treatment for pyelonephritis, a MRI revealed a large intra-abdominal cystic lesion. The patient subsequently underwent cesarean delivery and latter had tumor resection with distal pancreatectomy and splenectomy. Histopathological revealed a pancreatic MCN with low grade dysplasia. Our case strongly indicates the importance of further evaluation for uncommon causes for left flank pain.
