ABSTRACT
Objective To investigate the diagnostic value of 18F-fluorodeoxyglucose (FDG) PET/CT in the localization of ectopic adrenocorticotrophic hormone ( ACTH)-secreting tumors. Methods Seven patients with ectopic ACTH syndrome (confirmed by clinical symptom, biochemical data or bilateral simultaneous inferior petrosal sinus sampling) were included, 4 males and 3 females with age ranged 27-63 years old.All patients were examined with head MR, chest and abdomen CT, abdomen ultrasonography, and whole body 18F-FDG PET/CT. Location, size, and the maximum standardized uptake value (SUVmax) of the tumor were measured. Results 18 F-FDG PET/CT detected three ectopic ACTH-secreting tumors with the sizes 1. 1 cm×1.0 cm (SUVmax =9.4), 1.5 cm×1.1cm (SUVmax =6.4), and 1.6 cm ×1.5 cm (SUVmax =12.0). The pathological findings of the three tumors were thymoma, lung carcinoid, and mediastinal carcinoid respectively. Conclusion 18 F-FDG PET/CT may help the localization of ecto pic ACTH-secreting tumors .
