Prostate-specific membrane antigen (PSMA) is expressed on the endothelial cells of tumor-associated neovasculature of various nonprostatic benign and malignant neoplasms. Positive intense uptake on PET/CT imaging with 68Ga-labeled PSMA is noted in a patient with sinonasal glomangiopericytoma, and the same is noted to be absent following complete surgical excision. 68Ga-PSMA PET/CT may be a useful tool for early recurrence identification, differentiating recurrence from surgical site reparative tissues, and peptide receptor radionuclide therapy of residual lesions.
前列腺特异性膜抗原（PSMA）表达于各种非前列腺良性和恶性肿瘤相关新生血管的内皮细胞上。一位鼻窦血管外皮细胞瘤患者的 PET/CT 成像显示 68Ga 标记的 PSMA 摄取阳性且强烈，而在完全手术切除后则未见摄取。68Ga-PSMA PET/CT 可能是一种有用的工具，可用于早期复发的识别，区分复发与手术部位修复组织，并对残留病变进行肽受体放射性核素治疗。
