Polyneoplasias in uveal melanoma patients detected by positron emission tomography combined with computed tomography (two clinical cases)

Abstract

In addition to abdominal ultrasound and chest X-ray, positron emission tomography combined with computed tomography (PET/CT) has been increasingly used to diagnose metastatic disease in patients with uveal melanoma. We present two clinical cases of the second malignancy (synchronous polyneoplasia, colon cancer) that was eventually found during PET/CT in uveal melanoma patients performed to exclude dissemination of the neoplasm. It was shown that hybrid PET/CT is the most informative method in the diagnosis and monitoring of uveal melanoma patients. During one diagnostic procedure it enables to diagnose early stages of secondary malignancies, in addition to the assessment of metastatic dissemination.
