摘要

肢端肥大症是一种罕见的疾病，通常由生长激素分泌垂体腺瘤（GHPA）引起，神经影像学在肿瘤定位、特征和手术计划中起着重要作用。一名57岁男性因胰腺偶发病变行68Ga-DOTATOC PET/CT检查。PET显示放射示踪剂摄取增加，脑垂体肿大。18F-FDOPA和18F-FDG PET/MRI显示鞍区病变提示垂体腺瘤。切除肿瘤的病理检查证实为GHPA。

68 Ga- DOTATOC PET/CT, 18 F-FDOPA, and 18 F-FDG PET/MR Findings in Growth Hormone-secreting Pituitary Adenoma.

Acromegaly is a rare disease frequently caused by a growth hormone-secreting pituitary adenoma (GHPA), and neuroimaging plays an important role in tumor localization, characterization, and surgical planning. A 57-year-old man underwent 68 Ga-DOTATOC PET/CT for an incidental pancreatic lesion. The PET revealed an increased radiotracer uptake and enlargement of the pituitary gland. The study was completed with 18 F-FDOPA and 18 F-FDG PET/MRI, which revealed a sellar lesion suggesting pituitary adenoma. Pathological examination of the resected tumor confirmed a GHPA.
