Objective:To analyze the mammographic findings in plasma cell mastitis(PCM) and improve the diagnosis accuracy.Methods:Forty-seven cases of plasma cell mastitis having molybdenum mammography and confirmed by surgical pathology were observed and analyzed.Results:The mammographic findings included:mass(n=20)

piece-like and agglomerate-like image(n=20)

nodule(n=3)

subareolar ductal ectasia(n=2)

negative(n=2).Conclusion:Although no specific radiologic signs were found in PCM

the diagnosis accuracy of PCM can be improved by analysis of the common mammographic findings of PCM in combination with clinical features.
