Abstract:
Although cystic neoplasms of the pancreas are an uncommon disease, it occures often enough that proper sugicalmanagement depends on accurate preoperative diagnosis. It is very difficult to diagnose accurately by conventionalradiological methods alone. Angiographic findings are fairly characteristic for these tumors, but they are in noway specific. The imaging characteristics of ultrasonography and CT are particularly useful in the diagnosis ofthis particular tumors. This report presents an analysis of 2 cases of cystadenoma and 3 cases cystadenocarcinomaexamined by ultrasonography and CT. Ultrasonography findings are complelx multicytic mass in the pancreas withthick irregular wall, daughter cyst, septa and solid component. These septa and solid component are highlyechogenic if the tumor is mucin producing. Computed tomographic findings are large cyst possessing irregular thickwall, solid component and septa which are enhanced by contrast infusion. Punctate or curvilinear calcification isseen occasionally. Tortuous or beaded vascular collaterals are seen around the cyst. On the other hand, pseudocystis usually a single cyst possessing thin smooth wall, and solid component or septa are unusual in pseudocyst.
