From Radipedia
Contents
Pseudocysts
- Most common symptomatic cystic mass
- Pancreatic fluid encapsulated within thick, irregular, fibrous walls
- Result from acute pancreatitis
- Often calcifications in walls
- Don't drain until well formed (6-8 weeks) and don't drain if ductal disruption
Mucinous Cystadenoma
- Malignant low grade lesions
- Most commonly found in middle aged women (95%)
- Excellent prognosis with resection
- Well circumscribed with internal multiloculated cysts and thin septa
- Often six or less cysts about 2cm each
- Attenuation varies but does enhance
- Peripheral calcifications can occur
- Most commonly the tail
- Do not communicate with ductal system
Serous Cystadenoma
- Benign, no malignant potential
- Female to Male 4:1
- Tiny cysts contain clear fluid, but can have macrocystic type
- Stellate scar
- Central calcifications
- Can have a unilocular form which occur in the head
- Lobulated contour
True Pancreatic Cysts
- Rare, solitary epithelial lines cysts
- Associates with von Hippel-Lindau (50% patients) and ADPCKD (5%)
