We present the FDG and Ga DOTATATE PET/CT findings of a 68-year-old woman with pulmonary metastases 28 years after her initial diagnosis of central nervous system hemangiopericytoma. The largest of the pulmonary lesions showed prominent Ga DOTATATE uptake with comparatively minimal FDG avidity. Hemangiopericytoma is a rare mesenchymal tumor that arises from malignant pericytes, cells that form the walls of capillaries and postcapillary venules. This case demonstrates the potential of radiolabeled somatostatin analogs as a therapeutic option in the setting of widespread metastatic disease.
我们展示了一位 68 岁女性的 FDG 和 Ga DOTATATE PET/CT 结果，她在最初诊断为中枢神经系统血管外皮细胞瘤 28 年后出现了肺转移。最大的肺部病变显示出明显的 Ga DOTATATE 摄取，而 FDG 摄取相对较少。血管外皮细胞瘤是一种罕见的间叶性肿瘤，起源于恶性周细胞，这些细胞构成了毛细血管和小静脉后微静脉的壁。本病例显示了放射性标记的生长抑素类似物在广泛转移疾病背景下作为治疗选择的潜力。
