Abstract
Adrenocortical oncocytoma is a very rare
tumor, which is not malignant and nonfunctioning in most
cases. We report a case of a 53-year-old male with a 9.8 cm
sized hyperfunctioning, well-encapsulated adrenal mass,
which exhibited by high FDG uptake on a PET/CT scan.
The patient had complained of symptoms of Cushing’s
syndrome for 4 months. Laparoscopic adrenalectomy was
performed and the mass was pathologically confirmed as
adrenocortical oncocytoma of uncertain malignant potential.
Four years after surgery, the tumor recurred with
distant metastases, which was proven by subsequent
biopsy. 18F-FDG PET/CT also showed hypermetabolism in
the recurred tumor and multiple metastatic lesions. Adrenocortical
oncocytoma of borderline malignant potential
with high FDG uptake may require long-term follow-up
with clinical, hormonal, and imaging evaluations.
