View larger version (20K): [in a new window]   Fig. 1. —Graph shows time-signal intensity curve of mucinous carcinoma in seven of eight patients in our study. (Dynamic study was not performed in patient 7.) In four patients, contrast enhancement ratio after 60 sec is less than 100%, and slow contrast enhancement is observed. In three patients, curve plateaus after initial upstroke. Broken line represents time-signal intensity curve of component of solid tubular carcinoma in patient 6, and it shows wash out pattern.

T1-weighted (A) and T2-weighted (B) MR images show lobular mass. Low-signal lesions (solid tubular carcinoma, white arrow, B) around core of very high signal-lesions (mucinous carcinoma, black arrow, B) are seen on T2-weighted image.
