Abstract：
BACKGROUND:Colloid carcinomas of the pancreas have better prognosis than ordinary ductal adenocarcinoma, and preoperative distinction of colloid carcinoma from other pancreatic tumors is valuable for patient therapeutic planning and prognosis assessment. However, data about CT features of colloid carcinoma are very limited. This study aimed to investigate the CT features of this tumor. METHODS:Institutional review board approval was obtained for this study. Seven patients with pathologically proven colloid carcinoma of the pancreas were included. Unenhanced and dynamic enhanced CT was performed in all the patients. CT features were analyzed retrospectively and correlations with pathological findings were evaluated. RESULTS:Mean age of the patients was 59.8 years (41 - 76 years). Five tumors were located in the pancreatic head, and the other two in body and tail respectively. The maximum mean diameter of the tumors on axial scanning was 3.9 cm (3.0 - 6.7 cm). Tumors were round (n = 5) and lobular (n = 2). Tumors appeared slight hyp-attenuation on unenhanced CT, and peripheral and internal meshlike progressive delayed enhancement with great percent of cystic areas on enhanced CT. Calcification and gas in the tumor was seen in one patient whose duodenum was invaded by the tumor. CONCLUSIONS:Colloid carcinomas of the pancreas appear as round or labular masses with great percent of cystic areas and slight hyp-attenuation on unenhanced CT and peripheral and internal meshlike progressive delayed enhancement on enhanced CT.
