Bilateral Huge Incidentalomas of Isolated Adrenal Metastases From Unknown Primary Melanoma Revealed by 18F-FDG PET/CT.

FDG PET/CT has high sensitivity and specificity for the detection of distant metastases from cutaneous melanoma. Imaging is recommended for patients with clinical suspicion of metastasis and should be considered for those with confirmed sentinel lymph node metastasis. Metastatic melanoma bears a poor prognosis. Only a complete resection improves survival, which explains the need to detect potentially unresectable disease, and most metastatic patients are ineligible for a curative surgical procedure. Here, FDG PET/CT demonstrated isolated bilateral adrenal metastases from melanoma of unknown primary. The patient underwent curative surgery, with no sign of recurrence at 48 months after surgery.
