Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a rare fatal autosomal dominant vasculopathy associated with mutations in the TREX1 gene. Only one de novo case has been reported in the literature. We report the long-term clinical, radiological, and pathological presentation of a patient with a de novo and novel mutation in this gene. Description of the clinical, genetic, imaging and pathologic characteristics is important to better characterize RVCL-S and prevent unnecessary interventions. RVCL-S should be considered in patients with tumefactive brain lesions unresponsive to immunotherapy.
