MRI DIAGNOSIS AND PATHOLOGY ANALYSIS OF OVARIAN-ADENOMYOSIS CYST

Objective To analyze the MRI features of ovarian-adenomyosis cyst. Method MRI findings in 26 cases, 31 ovarian-adenomyosis cysts that were confirmed by surgical-pathology were analyzed retrospectively. Results In 27 ovarian-adenomyosis cysts which were coincident with surgical-pathology,13 lesions were both high-intensity signal in T1WI and T2WI; 7 lesions were high-intensity signal in T1WI but low or middle-intensity signal in T2WI ; 7 lesions were both mix signal in T1WI and T2WI.Of all cases, the margin in 17 lesions were unclear, part-unclear in 7 lesions, clear in 3 lesions. Conclusion 1 The MRI manifestations of ovarian-adenomyosis cyst is high or mix signal in T1WI、T2WI, mainly middle or high-intensity signal. 2 The signal of the ovarian-adenomyosis cyst in MRI are coincident with pathologic ingredient in it.
