We evaluated the MR imaging findings including DWI with
ADC measurement of five decidualized adenomyosis (DA): 4
were during pregnancy, and 1 was under hormonal therapy.
All DAs were demonstrated as heterogeneous signal
intensity on T2WI containing prominent bright foci
reflecting decidual reaction of endometrium within
adenomyosis. On DWI the decidualized endometrial foci
showed high signal intensity. The mean ADC of 4 DAs was
1.62 +/- 0.05, which was significantly higher than that
of 14 malignant uterine myometrial tumors (0.85 +/-
0.15) (p=0.003). We conclude that ADC measurement may be
helpful in distinguishing DA from malignant uterine
tumors.
