Key Points

This report aims to elucidate a case of concurrent renal carcinoid and giant cell arteritis using advanced imaging techniques.
Case report of a 69-year-old woman experiencing headache and bone pain.
Utilized [68Ga]Ga-DOTATOC PET/CT imaging to assess tumor recurrence and vascular involvement.
Measured erythrocyte sedimentation rate (ESR) as a marker for active giant cell arteritis.
[68Ga]Ga-DOTATOC PET/CT revealed multisite recurrent renal carcinoid activity.
An elevated ESR of 87 mm/h confirmed the diagnosis of giant cell arteritis.
Imaging demonstrated dual utility for tumor mapping and inflammation assessment in complex cases.

Abstract

Giant cell arteritis (GCA), the most frequent large-vessel vasculitis, typically involves medium to large arteries and occasionally coexists with malignancy. We report a 69-year-old woman with renal carcinoid who developed concurrent tumour recurrence and GCA. Following progressive symptoms of headache and bone pain, 68 GaGa-DOTA-Tyr3-octreotide ( 68 GaGa-DOTATOC) positron emission tomography/computed tomography (PET/CT) demonstrated multisite recurrent renal carcinoid, diffuse arterial and cardiac activity and heterogeneous 68 GaGa-DOTATOC-avid thoracic aortic aneurysm. An elevated erythrocyte sedimentation rate (ESR) of 87 mm/h confirmed active GCA. This case highlights the novel utility of 68 GaGa-DOTATOC PET/CT as a dual-purpose biomarker for both tumour mapping and vascular inflammation in complex clinical presentations.
