Abstract
BACKGROUND: Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations (RVCL-S) is a rare hereditary disease presenting with distinct imaging features in middle-aged adults. This article describes the typical imaging features focusing on the longitudinal course of RVCL-S lesions. METHODS: In this study six subjects (five male, five related) with RVCL-S were retrospectively included from two university hospitals. The median age of symptom onset was 40 ± 6 years. Magnetic resonance imaging (MRI) covering baseline and a median follow-up period of 33 months was reviewed in a structured way focusing on morphology, contrast enhancement and diffusion restriction of brain lesions. RESULTS: All patients showed patchy, T2 hyperintense white matter lesions (mean number 7.7 ± 1.8) with a periventricular predominance at the frontal lobes (59%). In all subjects, rim-enhancing white matter lesions with temporary diffusion restriction were present for a mean of 5.0 ± 3.9 months. Median duration of blood brain barrier disruption was 20 months. CONCLUSION: Periventricular patchy white matter lesions in the frontal lobes as well as rim-enhancing lesions with prolonged diffusion restriction and long-lasting contrast enhancement are characteristic imaging findings in RCVL-S and can be helpful in the differential diagnosis.
