Ga-labeled somatostatin receptor analogs physiologic distribution patterns have become recognizable among nuclear medicine physicians because of the increasing routine clinical use of this modality in the work-up of neuroendocrine tumors. Some pitfalls during Ga-labeled somatostatin receptor PET/CT have recently been reported as causes of misdiagnoses. Iatrogenic microembolism as a cause of F-FDG embolus is well-established; however, 68Ga-DOTATOC embolus is not well documented in the literature. In the current case, the presence and the spontaneous resolution of the Ga-labeled somatostatin receptor analogs embolus during sequential PET/CT are nicely demonstrated. Awareness of this incidental finding would avoid misdiagnosis and unnecessary investigations.
由于镓标记的生长抑素受体类似物在神经内分泌肿瘤检查中的临床应用日益常规化，其生理分布模式已为核医学医生所熟知。最近有报道称，镓标记的生长抑素受体PET/CT检查过程中存在一些陷阱，可导致误诊。医源性微栓塞作为F-FDG栓子的病因已得到充分证实；然而，68Ga-DOTATOC栓子在文献中尚无充分记载。在本病例中，镓标记的生长抑素受体类似物栓子在连续PET/CT检查过程中的出现及自发消散得到了很好的展示。认识到这一偶然发现可避免误诊和不必要的检查。
