MRI features of pancreatic colloid carcinoma

AJR Am J Roentgenol. 2009 Oct;193(4):W308-13. doi: 10.2214/AJR.09.2347.

Abstract

Objective: The purpose of our study was to retrospectively investigate the MRI findings (diameter, location, contour and margin, signal intensity characteristics, and enhancement patterns) in a series of eight patients with pathologically proven colloid carcinoma of the pancreas.

Conclusion: Colloid carcinomas of the pancreas appear as masses with lobulating contours, indiscrete margins, and hyperintensity on T2-weighted images (n = 8). In addition, all patients who underwent dynamic studies (n = 4) showed peripheral and internal sponge-like or mesh-like progressive delayed contrast enhancement.
