A 62-year-old female patient with suspected insulinoma underwent 68Ga DOTA-TATE PET/CT for characterization and staging. This demonstrated a focus of uptake in the pancreas and 3 foci of uptake in the spine. An MRI of the spine performed to further characterize the lesions revealed the presence of a meningioma and degenerative changes, both of which showed 68Ga DOTA-TATE uptake. A vertebral metastasis seen on PET was occult on CT and MRI. A vertebral hemangioma had no discrete tracer uptake. Awareness of sources of error in interpreting 68Ga DOTA-TATE scans is important in order to avoid pitfalls.
一位 62 岁女性疑似胰岛素瘤患者进行了 68Ga DOTA-TATE PET/CT 检查以进行特征分析和分期。结果显示胰腺有一处摄取病灶,脊柱有 3 处摄取病灶。为进一步分析病变特征对脊柱进行了 MRI 检查,结果显示存在脑膜瘤和退行性改变,这两种病变均显示 68Ga DOTA-TATE 摄取。PET 上所见的椎体转移灶 CT 和 MRI 均为阴性。椎体血管瘤无明显示踪剂摄取。了解解读 68Ga DOTA-TATE 扫描时的误差来源非常重要,以免陷入陷阱。
