ABSTRACT
Angiographic findings in one giant cell carcinoma, one cystadenocarcinoma, one poorly vascularized mucinous cystadenocarcinoma, as well as in two avascular (gastrin- and glucagon-producing) islet-cell tumors of the pancreas are described. Two hypervascularized islet-cell tumors are presented for comparison and a case of tumorous chronic pancreatitis in a child is reported because ot its rarity. The aggressiveness of the giant cell carcinoma of the pancreas was demonstrated by its expansive growth. In the case of cystadenocarcinoma angiography revealed the tumor with hepatic metastases not diagnosed at explorative laparotomy. The relative hypovascularity in the case of mucinous cystadenocarcinoma was unusual. Both avascular islet-cell tumors simulated a pancreatic pseudocyst and the final diagnosis was made only by immunoassay. Chronic pancreatitis in a child presented with marked hypervascularization.
