Uveal Melanoma Metastatic to the Cavernous Sinus: A Case Report.
A woman in her early 50s previously treated 7 years prior with iodine-125 plaque brachytherapy without a biopsy for gene expression profiling for uveal melanoma in the left eye presented with a 3-week history of intermittent diplopia and headache. Ophthalmic examination was significant for limitation in left eye upward gaze; otherwise, examination revealed a stable, regressed tumor in the left eye, and normal vision, pressure, and pupils in both eyes. Neuroimaging showed a left cavernous sinus lesion, suggestive of a meningioma. Excisional biopsy revealed metastatic melanoma. The patient was treated with radiotherapy, and her diplopia resolved. Slight enlargement of the lesion was noted on neuroimaging 20 months later, and was treated with stereotactic radiosurgery. Serial neuroimaging in the following 6 months did not reveal any recurrences or new metastases. This case demonstrates the importance of investigating persistent diplopia in a patient with a history of uveal melanoma, and the possibility of metastases occurring in organs besides the liver or lung.
