68Ga-DOTATOC Embolus Manifestation and Spontaneous Resolution by PET/CT

Abstract68Ga-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 during68Ga-labeled somatostatin receptor PET/CT have recently been reported as causes of misdiagnoses. Iatrogenic microembolism as a cause of18F-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 the68Ga-labeled somatostatin receptor  analogs embolus during sequential PET/CT are nicely demonstrated. Awareness of this incidental finding would avoid misdiagnosis and unnecessary investigations.
