title: Baker's Cyst on F-18 FDG PET/CT in a Patient with Ocular Melanoma.
abstract: We present the case of a 56-year-old man with the clinical diagnosis of ocular melanoma. As a part of staging, he underwent an F-18 FDG PET/CT scan for investigating distant metastasis. On PET scan, an increased focal area of F-18 FDG uptake was seen behind patient's right knee that can be confused with distant metastasis. On CT scan, there was a fluid density in the same location. The probable diagnosis was Baker's cyst. Later, USG and MRI confirmed this diagnosis.
