Epidemiology Brugge WR. et al. N Engl J Med.351:1218-26.2004.
Serous Cystadenoma • Microcystic, serous, or glycogen-rich adenomas • Presentation • 50-60% have abdominal pain (up to 25 cm) • 30% palpable mass • Occ. obstructive jaundice, pancreatitis, pancreatic insufficiency, or gastric outlet obst. • 25% small & asymptomatic found on CT Levy MJ & Clain JE. Clin Gastroenterol Hepatol.2(8):639-53.2004.
Serous Cystadenoma • Focal, well-demarcated lesions • Multiple (>6), small (<1-2 cm), fluid-filled microcysts • Dense fibrous septations give honeycomb appearance 8 mm Levy MJ & Clain JE. Clin Gastroenterol Hepatol.2(8):639-53.2004.

WHO Classification Mucin-producing cystic neoplasms of the pancreas Intraductal Papillary Mucinous Neoplasm (IPMN) Mucinous cystadenoma Mucinous cystadenocarcinoma
Mucinous Cystadenoma • Macrocystic adenoma • Premalignant • 25% contain malignancy at time of diagnosis • Presentation • Pain (60-80%) • Diabetes (25%) • Pancreatitis (10-20%) • Incidental (10-30%) • Ovarian stroma Grogan JR et al. AJR 176:921-9.2001. Levy MJ & Clain JE. Clin Gastroenterol Hepatol.2(8):639-53.2004.
Intraductal Papillary Mucinous Neoplasm (IPMN) Main Duct Variant Side Branch Variant Grogan JR et al. AJR 176:921-9.2001.
IPMN • Presentation • Pain (50-100%) • Acute pancreatitis (22-45%) • Asymptomatic (up to 30%) • Variants • Main duct (47-75%) • Side branch (25-39%) • Both (14%) Levy MJ & Clain JE. Clin Gastroenterol Hepatol.2(8):639-53.2004.
Evaluation of PCNs • 10-37% initially diagnosed erroneously as pseudocyst • Delay in diagnosis • Lost opportunity for curative resection • Type of PCN • Demographics • Radiology • EUS with FNA

Pancreatic Cyst Fluid Analysis Levy MJ & Clain JE. Clin Gastroenterol Hepatol.2(8):639-53.2004.
Pancreatic Cyst Fluid Analysis • 19 pancreatic cystic masses, 31 pseudocysts • CA 19-9 > 50,000 U/mL • Sens 75%, Spec 90% • MCN > other cysts • CEA < 5 ng/mL • Sens 100%, Spec 86% • SCN > other cysts • Amylase > 5,000 U/mL • Sens 94%, Spec 74% • Pseudocysts > other cysts Hammel P. et al. Gastroenterology.108:1230-5.1995.
Diagnosis of Pancreatic Cystic Neoplasms • Multicenter trial • 341 pts EUS-FNA • 112 pts surgical resection • Prospective evaluation: • EUS imaging, • Cyst fluid cytology, • Cyst fluid tumor markers • CEA, CA 72-4, CA 125, CA 19-9, and CA 15-3 Brugge WR. et al. Gastroenterology.126:1330-6.2004.
Diagnosis of Pancreatic Cystic Neoplasms Accuracy • CEA • (88 of 111, 79%) • EUS morphology • (57 of 112, 51%) • Cytology • (64 of 109, 59%) Brugge WR. et al. Gastroenterology.126:1330-6.2004.
