Abstract:
Objective To compare the appearances between chronic mastitis and breast cancer on MRI and investigate the differ-ential diagnostic value.Methods MRI data of 20 patients with chronic mastitis pathologically proved by biopsy or operation were ret-rospectively analyzed.30 cases of breast cancer were contemporaneously chosen as the control group.Morphological feature and dy-namic contrast-enhanced(DCE)manifestation of the lesions were evaluated and statistical difference was compared between mastitis and breast cancer.Morphological feature included configuration,spiculated sign,ring-like enhancement,peri-focal edema,skin thick-ening,nipple involvement and axillary lymph nodes enlargement.DCE manifestation contained calculating early enhancement ratio and drawing time-intensity curve (TIC).Results There were significant statistical differences among configuration,ring-like en-hancement and peri-focal edema between mastitis and breast cancer,respectively.No statistical differences could be found among spiculated sign,skin thickening,nipple involvement and axillary lymph nodes enlargement.Early enhancement ratio in the group of mastitis was 1.1 56±0.635 while 1.253±0.499 in the group of breast cancer and there was no statistical difference between them. There were 1 1 cases with type Ⅰ TIC,6 with type Ⅱ,3 with type Ⅲ in the lesions of mastitis,while 4 with type Ⅰ,1 1 with typeⅡ,1 5 with type Ⅲ in the lesions of breast cancer and significant statistical differences could be found between two groups.Conclu-sion Mastitis usually manifests as non-mass-like lesions on MRI.Ring-like enhancement,peri-focal edema and benign type TIC can be applied to discriminate mastitis from breast cancer.
