Metastatic papillary renal cell carcinoma to the retina and vitreous.
PURPOSE: To describe the presentation, evaluation, and management of vitreoretinal metastasis from papillary renal cell carcinoma.
OBSERVATIONS: A 53-year-old woman presented with a six-week history of dark floaters in the right eye. Vitreous veils and white pre-retinal plaques were identified in the posterior pole and extended to a temporal peripheral lesion suggestive of retinal infiltration. Optical coherence tomography revealed clumps of pre-retinal hyper-reflective material in the macula and a large hyper-reflective plaque-like lesion involving the internal limiting membrane in the temporal periphery. Fluorescein angiography demonstrated patchy hyperfluorescence with mild leakage at the temporal lesion and there was no evidence of choroidal involvement on indocyanine green angiography. Vitreoretinal biopsy confirmed the diagnosis of metastatic papillary renal cell carcinoma which spurred further systemic metastatic evaluation. Choroidal metastasis developed 15 months later in the fellow eye highlighting different types of intraocular metastatic spread in the same patient.
CONCLUSIONS AND IMPORTANCE: This case report illustrates a rare presentation of papillary renal cell carcinoma with metastasis to the retina and vitreous. Ophthalmologists should be aware of the appearance and imaging characteristics of retinal and vitreous metastases, which can be the first presentation of a new or newly metastatic malignancy. These lesions can resemble infectious or inflammatory mimickers and may require biopsy to secure the diagnosis and to guide vision- and life-preserving treatment.
