侵袭性微乳头状癌（IMPC）是一种罕见的侵袭性乳腺癌亚型，由于局部复发率高和淋巴管侵犯，预后较差。有趣的是，IMPC 通常不会在乳房 X 光检查中显示与恶性肿瘤相关的可疑钙化模式。因此，缺乏可疑钙化使得乳房X光检查难以检测出乳腺癌。由于乳房X光检查仅显示非特异性钙化，我们在初始分期检查期间在IMPC乳腺癌患者的全身骨闪烁扫描中观察到异常的瘤内99mTc-DPD摄取，并将其特征与乳房X光检查结果和术后病理特征进行了比较。版权所有© 2023 Wolters Kluwer Health, Inc. 保留所有权利。

Invasive micropapillary carcinoma (IMPC) is a rare and aggressive subtype of breast cancer with a poorer prognosis due to high local recurrence and lymphovascular invasion. Interestingly, IMPC often does not show suspicious patterns of calcifications related to malignancy on mammography. Therefore, the lack of suspicious calcifications makes it difficult to detect breast cancer on mammography. With only nonspecific calcifications on mammography, we observed an unusual intratumoral 99mTc-DPD uptake on whole-body bone scintigraphy in an IMPC breast cancer patient during the initial staging workup, and its characteristics were compared with mammographic findings and the postoperative pathologic features.Copyright © 2023 Wolters Kluwer Health, Inc.
