Abstract

A 65-year-old woman with known breast cancer presented with lower back pain over 1 month. Multiple sclerotic foci of increased tracer uptake in the bones were noted on the Tc-MDP bone scintigraphy and SPECT/CT images, suggesting osteoblastic metastasis. Unexpectedly, symmetric Tc-MDP activity was visualized in the soft tissue near the umbilical area, corresponding to the sites of insulin injection.

摘要

一位 65 岁的已知患有乳腺癌的女性患者出现了 1 个月以上的下腰痛。Tc-MDP 骨闪烁显像和 SPECT/CT 图像上可见多处骨硬化病灶摄取增加的放射性示踪剂，提示成骨性转移。出乎意料的是，在脐周区域附近的软组织中可见对称的 Tc-MDP 活性，与胰岛素注射部位相对应。
