We report a case of a 70-year-old female with traumatic neuroma of the bile duct. Transpapillary intraductal ultrasonography showed a cystic duct stump, from which a smooth and homogeneous hypoechoic mass arose; the adjacent bile duct wall had a normal structure. Intraductal ultrasonography is useful for distinguishing traumatic neuroma from bile duct carcinoma.
It has been reported that ovarian fibromas display low signal intensity on both T1- and T2-weighted magnetic resonance images. We report an ovarian fibroma exhibiting low signal intensity on a T1-weighted image and high signal intensity on a T2-weighted image. Microscopically pronounced myxomatous changes were shown in the fibroma. The signal intensity of ovarian fibromas differs with the degree of myxomatous change.
