May 2018 — Gastroenterology

A 33-year-old woman presented with abdominal cramps and intentional weight loss of 27 pounds. Abdominal CT revealed a right ovarian cyst suspicious for teratoma and a cystic mass posterior to pancreatic head. EUS-guided ultrasound showed a 4 x 3 cm cyst filled with mobile intracystic material. Cystic fluid analysis revealed increased amylase (26, 376 U/L) and increased CEA (5266 ng/mL). A Whipple-procedure was performed. Gross examination revealed a unilocular cystic mass (2.5 x 2.1 x 2.0 cm) along the periphery of pancreas, containing mucinous debris.
