18F-FDG PET/CT in nonfunctioning adrenocortical carcinoma diagnostics. Clinical observation.

Clinical observation of the patient with adrenocortical cancer recurrence after adrenalectomy and multiple treatment. A 46 year old man was diagnosed with adrenal mass. Endocrine activity was excluded. Due to local cancer advancement, the patient was given a radical treatment. After 5 years after surgical treatment, a local recurrence of the disease was detected according to the results of CT. For further restaging the patient underwent PET/CT with 18 F-FDG, according to the results no distant metastases were detected. After complex treatment and observation period metastases were diagnosed. This clinical observation demonstrates possibilities of PET/CT with 18 F-FDG – PET/CT, helps to determine nature of adrenal mass formations, revealing signs of their malignancy and is a valuable tool in adrenocortical cancer in cases of recurrent disease and in cases of metastatic lesions.
