Abstract

Rationale:: Mucinous cystic neoplasms (MCNs) of the pancreas are uncommon tumors that occur during pregnancy, but because MCNs of the pancreas are sex hormone responsive, these tumors can grow rapidly. We report a case of MCN of the pancreas that was diagnosed during pregnancy.

Patient concerns:: A 19.4 × 14.5 cm lesion was detected in the left upper abdomen in a 36-year-old asymptomatic woman with chronic hypertension and diet-controlled gestational diabetes at a gestational age (GA) of 36 weeks.

Diagnoses:: Magnetic resonance imaging showed a multiseptated cystic mass with a regular thin wall arising from the pancreatic tail, and final pathological findings identified a pancreatic MCN with high-grade neoplasia and no metastasis.

Interventions:: At a GA of 37+2 weeks, acute severe hypertension raised suspicion for superimposed preeclampsia, and cesarean delivery was performed. Laparoscopic distal pancreatectomy with splenectomy was performed 11 weeks postpartum.

Outcomes:: The postoperative course was uncomplicated, and a 6-month follow-up was planned without further treatment.

Lessons:: The optimal timing of surgical resection for MCNs of the pancreas in pregnancy should be determined by the GA and the potential for malignancy. If malignancy is not suspected, planned postpartum resection is a safe approach.
