Aim to describe the mammographic and ultrasonographic features of pure mucinous breast cancer.
The mammographic features of 15 patients and ultrasonographic features of seven patients with pure mucinous breast cancer were reviewed retrospectively by three experienced breast radiologists.
The commonest mammographic appearance was of a poorly defined (86%) lobulated (71%) mass which could contain calcification (14%). A well defined mass (14%) and suspicious calcifications without a mass (7%) were also seen. Ultrasound showed a mass lesion in all seven cases which was either hypoechoic (86%) or mixed echogenicity (14%); 86% had a heterogeneous internal echo pattern; 71% showed distal enhancement while none showed distal attenuation.
The imaging features of pure mucinous cancer are different from more common types of breast carcinoma. It is possible to misinterpret the appearances of this slow growing tumour as a benign lesion due to rarity of speculation on mammography and distal attenuation on ultrasonography. Most cases do, however, show other features suggesting malignancy.
目的是描述纯黏液性乳腺癌的乳腺X线摄影和超声特征。
三位经验丰富的乳腺放射科医生回顾性分析了15例纯黏液性乳腺癌患者的乳腺X线摄影特征以及7例患者的超声特征。
最常见的乳腺X线表现为边界不清（86%）的分叶状（71%）肿块，可伴有钙化（14%）。也可见边界清晰的肿块（14%）和无肿块的可疑钙化（7%）。超声检查显示所有7例均有肿块病变，其中低回声（86%）或混合回声（14%）；86%内部回声不均匀；71%有远端增强，无远端衰减。
纯黏液性癌的影像学特征与更常见的乳腺癌类型不同。由于乳腺X线摄影表现罕见且超声无远端衰减，可能会将这种生长缓慢的肿瘤表现误诊为良性病变。然而，大多数病例确实显示出其他提示恶性的特征。
