Bilateral uveal metastases from papillary thyroid carcinoma are extremely rare. A 36-year-old woman with a 12-month history of papillary thyroid carcinoma presented with sudden loss of visual acuity and fields in the left eye. An examination and B-scan revealed a large, solid choroidal lesion in the left eye causing exudative retinal detachment. A small solid mass was also observed in the right eye fundus. Following left eye enucleation, immunohistopathology confirmed metastatic papillary thyroid carcinoma. The authors report the third known case of bilateral choroidal metastases.
Wider use of chemotherapy and targeted agents can be associated with posterior reversible encephalopathy syndrome (PRES). This syndrome is most commonly found in metastatic adenocarcinoma treated with platinum-based analogs and is managed with cessation of the precipitating medication. We present the first case of PRES in early-stage breast cancer and discuss the further management of this condition. Recognition of this condition and correction of identifiable precipitating factor including cessation of relevant medications remains important in its management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
