Adenoma malignum of uterine cervix in Peutz-Jeghers syndrome: CT and US features.

We report CT and ultrasound (US) features of adenoma malignum of the uterine cervix in a patient with Peutz-Jeghers syndrome (PJS) in whom bilateral ovarian mucinous cystadenomas and sex cord tumors with annular tubules were associated. Adenoma malignum was shown as a hyperechoic mass mixed with multiple cysts on US and a low attenuated endocervical mass on CT. We think that imaging demonstration of an endocervical mass is important for the correct diagnosis of adenoma malignum in a female with PJS
