(A) CT scan revealed a 21 x 13 mm low-density mass (about 9 HU). The enhanced adrenal gland CT revealed a significant enhancement of the mass (about 70 HU). (B,C)
68Ga-pentixafor PET/CT revealed that the maximum standardized uptake was 22.83.

Then, the patients underwent adrenal regional 68Ga-Pentixafor PET/CT imaging, which revealed a remarkably elevated uptake of the mass, with the maximum standardized uptake being 22.83, which strongly suggested an APA (Figure 1).
Gross pathological, histological and immunohistochemical findings. (a) Gross pathology revealed a 61 x 27 x 8 mm golden-yellow adenoma, which was connected to the right adrenal gland. (b) Hematoxylin-eosin staining, C: Normal adrenal cortex, M: Adrenal medulla; APA: Aldosterone-producing adenoma. (c) Immunohistochemical staining with CYP11B2.

Pathological examination revealed a golden-yellow tumor with intact capsule sized 34 x 25 x 13 mm and connected to the right adrenal gland (Figure 2). Additionally, immunohistochemical staining with CYP11B2 yielded positive results, which strongly suggested a pathological diagnosis of APA (Figure 2).
