An Intraocular Thymic Metastasis Identified on 18F-FDG PET/CT Before and After Treatment

Clin Nucl Med. 2021 Mar 1;46(3):240-242. doi: 10.1097/RLU.0000000000003431.

Abstract

We present the imaging findings pretreatment and posttreatment in a 58-year-old woman with recurrent thymic carcinoma. Two years after treatment, the patient presented with a 3-week history of right eye pain and blurred vision. Ophthalmological examination and MRI of the orbits showed a right superolateral choroidal lesion. Neurologic and whole-body FDG PET/CT scans showed a markedly glucose-avid right choroidal mass and extensive lung parenchymal, pleural, and thoracic nodal disease. There was a good response to chemoradiotherapy with a reduction in size and metabolism at all sites.
