title: Value of (18)F-FDG-PET/CT in ocular sebaceous adenocarcinoma: a case report and literature review.
abstract: Ocular sebaceous adenocarcinoma is a rare malignant tumor. We report an unusual case of orbital sebaceous adenocarcinoma in a 48-year-old woman. The patient underwent F-18 2-fluoro-2-deoxy-glucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) to determine the initial clinical stage. (18)F-FDG-PET/CT showed strong uptake in the orbital lesion, but neither regional lymphatic nor distant metastases were seen. (18)F-FDG-PET/CT plays a role in the diagnosis, staging, restaging, and follow-up of ocular sebaceous carcinoma, although its application has some limitations in other primary and ocular malignancies due to the rarity of ocular sebaceous carcinoma.
