The association between microangiopathic damage and both Raynaud's phenomenon and systemic sclerosis is well-established, leading to the adoption of nailfold video-capillaroscopy (NVC) as a non invasive diagnostic tool for the initial clinical assessment of these conditions.Case PresentationWe present a case study of a 42-year-old female patient with Raynaud's phenomenon in MS. The patient underwent NVC in 2023 showing microvascular impairment and after one year and Natalizumab treatment she repeated NVC evaluation with significant improvement in previous microangiopathic changes. A comprehensive literature review regarding the relationship between MS and Raynaud's phenomenon was conducted using electronic databases (PUBMED, UpToDate, Google Scholar, ResearchGate), along with manual searches for relevant articles published up to December 2024.DiscussionThis case highlights the potential utility of NVC in the ongoing evaluation of microangiopathic damage in MS patients exhibiting Raynaud's phenomenon.

CEUS was performed at the maximal solid tumor component identified on gray-scale imaging, with bolus injection of contrast agent and dynamic recording of the wash-in to wash-out phases for quantitative contrast kinetics analysis. A comparative analysis of US and CEUS characteristics was conducted between the groups, with subsequent longitudinal assessment of recurrence-free survival (RFS) curves employing Kaplan-Meier methodology.ResultsThe study comprised 58 patients with BOTs, stratified into low-risk (n = 37) and high-risk (n = 21) groups, with mean patient ages of 42.8 ± 11.8 years.
