目的探讨乳腺脂肪坏死的X线表现,提高对脂肪坏死的认识。方法回顾性分析15例经手术、病理证实的乳腺脂肪坏死X线平片表现。结果X线片表现:⑴表现为肿物4例(26.7%);⑵脂性囊肿2例(13.3%);⑶表现为小结节2例(13.3%);⑷脂肪层内索条影交织呈网状2例(13.3%);⑸脂肪层内星芒影、斑片影、索条影混杂出现3例(20%);⑹结构不良1例(6.7%);⑺无任何异常X线表现1例(6.7%)。结论乳腺脂肪坏死根据其病因和时期,其影像表现多种多样,X线表现位于乳腺脂肪层内的网状片影或有毛刺的结节,紧密结合临床病史,首先考虑脂肪坏死的可能,可提高本病诊断准确性,乳腺X线摄影对于脂肪坏死具有诊断价值。
Objective To investigate the X-ray findings of breast fat necrosis and improve the understanding of fat necrosis. Methods The clinical manifestations of 15 cases of breast fat necrosis confirmed by surgery and pathology were analyzed retrospectively. Results X-ray showed: ⑴ manifested as mass in 4 cases (26.7%); ⑵ lipocysts in 2 cases (13.3%); ⑶ showed nodules in 2 cases (13.3% (13.3%) in the reticular area; ⑸ There were 3 cases (20%) of astral shadow, patchy spots and clasps in the fat layer; 1 case (6.7%) of poor structure; 1 case (6.7%). Conclusion According to its etiology and period, breast fat necrosis has various imaging manifestations. X-ray shows reticular stripe or burr nodules located in the fat layer of the mammary gland. It is closely related to the clinical history and may consider the possibility of fat necrosis. To improve the diagnostic accuracy of this disease, mammography has diagnostic value for fat necrosis.
