Multimodal Imaging of Adult-onset Coats’ Disease

Abstract

The majority of Coats’ disease cases are diagnosed in the first decade of life, though cases with symptom onset and first diagnosis in adulthood are well documented. While the cases diagnosed in childhood and adulthood share many of the characteristic features that define Coats’ disease, adult cases have been shown to present with less severe disease manifestations and an increased incidence of macroaneurysms with perianeurysmal hemorrhage. We present two cases of Coats’ disease diagnosed in adulthood that demonstrate prominent arteriolar macroaneurysms with perianeurysmal hemorrhages and contribute to an understanding of the adult Coats’ phenotype.
