Fused 18F-Choline PET/MRI: A potential non-invasive biomarker imaging tool in cerebral vasculitis

Abstract

Primary CNS vasculitis is an inflammatory brain disease commonly misdiagnosed affecting the medium and small vessels of the CNS. Due to its broad and non-specific clinical and radiological manifestations; Its diagnosis remains challenging. New diagnostic tools and biomarkers which increase specificity and facilitate the diagnosis for patients with suspected vasculitis are highly desirable to enable physicians to start therapy that can alter its potential aggressive course like immunosuppressant.This case report highlights the potential role of 18F-choline PET/MRI as a novel imaging tool that might help in the right clinical scenario in the diagnosis of this disease.Furthermore, it speculates on its secondary role in monitoring the response to immunosuppressant therapy.
