Ga-DOTA-peptide PET/CT is a valuable tool for diagnosing neuroendocrine tumors (NET). Various tumors and normal human tissue express the somatostatin receptor (SSTR), warranting attention to positive findings on Ga-DOTA-peptide PET/CT. However, overexpression of SSTR in glomus tumors has not yet been reported. Gastric glomus tumors show many similar features of NET and are often misdiagnosed. We present the case of a 61-year-old male with a glomus tumor who underwent distal gastrectomy under the pretense of an NET grade 1 because the nodule showed focal intense uptake on preoperative Ga-DOTATOC PET/CT.
镓标记的DOTA肽PET/CT是诊断神经内分泌肿瘤（NET）的一种有价值的工具。各种肿瘤和正常人体组织均表达生长抑素受体（SSTR），因此镓标记的DOTA肽PET/CT上的阳性结果值得关注。然而，尚未有文献报道血管球瘤中SSTR的过表达情况。胃血管球瘤表现出许多与NET相似的特征，常被误诊。我们报告了一例61岁患有血管球瘤的男性病例，该患者因术前镓标记的DOTA-TOC PET/CT显示结节有局灶性强烈摄取，在疑似1级NET的情况下接受了远端胃切除术。
