Overview
Cystic neoplasms of the pancreas are abnormal fluid-filled sacs that can be benign or malignant. They
vary in their biological behavior and management approaches.
1. Serous Cystadenoma
Serous cystadenoma is a benign neoplasm characterized by the presence of multiple small cysts. They
are typically asymptomatic and more common in women.
- Symptoms: Often asymptomatic; may cause abdominal pain if large.
- Diagnosis: Imaging (CT or MRI) shows small cysts; fluid is usually clear.
- Treatment: Surgical resection is rarely necessary unless symptomatic.
2. Mucinous Cystadenoma
Mucinous cystadenoma is a neoplasm that produces thick, mucinous fluid. These lesions can become
malignant and are more common in women.
- Symptoms: Abdominal pain, nausea, and potentially jaundice.
- Diagnosis: Imaging shows a unilocular or multilocular cyst; cytology may reveal
mucin.
- Treatment: Surgical resection is usually indicated due to the risk of
malignancy.
3. Intraductal Papillary Mucinous Neoplasm (IPMN)
IPMN is a cystic neoplasm arising from the pancreatic duct that secretes mucin. It can be classified
as main duct or branch duct type.
- Symptoms: Abdominal pain, jaundice, and pancreatitis-like symptoms.
- Diagnosis: MRI or CT shows dilated pancreatic duct; endoscopic ultrasound may
help.
- Treatment: Surgical resection for high-risk lesions; surveillance for low-risk
cases.
4. Solid Pseudopapillary Tumor (SPEN)
SPEN is a rare pancreatic tumor, often found in young women. It has a low malignant potential but can
be aggressive.
- Symptoms: Abdominal pain, nausea, and a palpable abdominal mass.
- Diagnosis: Imaging shows a well-circumscribed mass; histology shows solid and
cystic areas.
- Treatment: Surgical resection is the treatment of choice, with good prognosis
in most cases.
