Abstract：
Skeletal scintigraphy has a pivotal role in detecting a number of bone pathologies, but it has its own limitations because of 2D image acquisition. Hybrid imaging acts as a savior in these cases where it is difficult to distinguish between benign and malignant lesions just on the basis of planar images. We present one such case of known breast carcinoma with abnormal increased radiotracer uptake in the skull which was difficult to characterize as benign lesion such as hyperostosis frontalis or metastatic osseous lesion. The importance of describing this case is to have a thorough understanding of hyperostosis patterns and to not confuse it with metastatic deposits in patients with known malignancies.
摘要：
骨骼闪烁显像在检测多种骨病变中具有关键作用，但由于2D图像采集有其自身的局限性。在这些情况下，仅根据平面图像很难区分良性和恶性病变，混合成像充当救星。我们介绍了一例已知的乳腺癌，其颅骨中放射性示踪剂的摄取异常增加，这很难表征为良性病变，例如额骨肥大或转移性骨性病变。描述这种情况的重要性是要彻底了解骨增生的模式，并且不要将其与已知恶性肿瘤患者的转移性沉积物混淆。
