Abstract

To describe the evolution of a "collar-button" or mushroom-shaped choroidal metastasis. Case report. A 52-year-old woman with known primary colon cancer and widespread extraocular metastases developed bilateral choroidal masses with neurosensory retinal detachments. Clinical and ultrasound evaluation demonstrated evolution of a choroidal metastasis with a "collar-button" configuration in the right eye. A choroidal metastasis may develop a mushroom-shaped configuration. This "collar-button" configuration is not pathognomonic for choroidal melanoma.
