PET/CT predicts brain tumors in melanoma patients

PET/CT scans have the potential to predict brain metastasis in melanoma patients.

January 3, 2024

A 49-year-old patient with primary clinical stage III melanoma underwent F-18 FDG-PET. The primary tumor Breslow thickness was 6.5 mm. On initial F-18 FDG-PET images, this patient had a high SUVmax (52), resulting in limited survival with the occurrence of brain metastasis in the first year of follow-up (horizontal arrow). Notably, during the course of the treatment, the patient underwent surgical removal of the primary tumor as well as lymph node dissection, followed by neoadjuvant radiotherapy and immunotherapy.
