摘要
目的探讨肉芽肿性乳腺炎(granulomatous mastitis,GM)的临床表现与X线及MRI诊断特点。资料与方法对31例经病理证实的GM患者的临床表现与X线及MRI资料进行回顾性分析。结果临床表现为乳房肿块短期内迅速增大,边缘不清与皮肤有粘连,部分伴有腋窝淋巴结肿大;钼靶X线表现呈多样性,病灶呈等密度或稍高于腺体密度结节状不规则影多见,部分显示局限性致密影结构紊乱,边缘不清、毛糙分叶及不规则状;MRT1WI呈等或高信号,T2WI呈高信号,增强扫描病变呈片状强化,高于周围正常腺体,边缘呈渐进性强化。结论 GM临床表现缺乏特异性,与乳腺X线与MRI相结合有助于准确诊断。
Objective To explore the clinical radiographic findings and magnetic resonance imaging features of granulomatous mastitis.Materials and Methods The clinical radiographic findings and magnetic resonance imaging data from 31 patients with granulomatous mastitis proved by pathological results were analyzed retrospectively.Results The clinical findings of GM were quickly augmentation of lump in breast in short time,ill-defined margin and adherence to skin,some lesions often accompanied by intumesce of axillary nodes.The radiographic findings of GM demonstrated diversity.The lesions’ density were found as isodense or higher than glands density with irregular tubercle.Some lesions of GM displayed as architectual distortion of local asymmetric density,ill-defined margin,ruffled,lobulated and irregular.The MR signs of GM lesions included hyper or isointensity signal on T1WI images,hyperintensity signal on T2WI images.The granulomatous mastitis lesions appeared pathcy enhancement,which was higher than that of normal glands adjacent to tumor,the border appeared gradually enhancement.Conclusion Granulomatous mastitis has no specific clinical findings,combination molybdenum target radiography and magnetic resonance imaging is helpful for the diagnosis of granulomatous mastitis.
