68Ga DOTA-TOC Uptake in Non-ossifying Fibroma: a Case Report
Khalaf Aysar,Hirmas Nader,Anwer Farah,Akram Al-Ibraheem 대한핵의학회 2020 핵의학 분자영상 Vol.54 No.4
Non-ossifying fibroma (NOF) is a common benign bone tumor with a high probability of occurrence in children and adolescents. It is commonly seen in the metaphysis of long bones, eccentrically located, and can coexist with other malignant tumors such as neuroendocrine tumors (NET). To date, plain radiographs play a major role in the diagnosis of these benign bone tumors. Herein, we report the case of a 13-year-old male patient who was diagnosed with pulmonary NET and underwent right lung lobectomy for a hilar mass which later revealed a well-differentiated NET. The follow-up 68Ga DOTA-TOC PET/CT showed a focal somatostatin receptor expression in the left distal femur, with corresponding CT component findings of a well-defined osteolytic bone lesion located within the medial aspect of the left distal femoral metaphysis, strongly indicative of NOF. To the best of our knowledge, this is the first reported case of such an occurrence.

68Ga-DOTATOC Embolus Manifestation and Spontaneous Resolution by PET/CT
Akram Al-Ibraheem,Deya’ Aldeen Sweedat,Anwer Farah,Feras Istatieh,Malik E. Juweid 대한핵의학회 2022 핵의학 분자영상 Vol.56 No.4
68Ga-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 68Ga-labeled somatostatin receptor PET/CT have recently been reported as causes of misdiagnoses. Iatrogenic microembolism as a cause of 18F-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 68Ga-labeled somatostatin receptor analogs embolus during sequential PET/CT are nicely demonstrated. Awareness of this incidental finding would avoid misdiagnosis and unnecessary investigations.
