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.

(A) Mammographic magnification view shows grouped calcifications in the left breast (circle). Stereotactic biopsy yielded grade 2 DCIS. Patient underwent a lumpectomy with tumor-negative surgical margins and radiation therapy. (B) Mammographic magnification view obtained four years after diagnosis shows new calcifications at the surgical site (circle). Stereotactic biopsy was performed, which revealed recurrent grade 2 DCIS. The patient then underwent a mastectomy. Image courtesy of the ARRS.

Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.
