Magnetic Resonance Imaging Findings Related to Stroke Risk in Japanese Patients With Fabry Disease.

Abstract

Background and Purpose- Stroke is the most frequent severe clinical event in patients with Fabry disease. We aimed to evaluate the cerebral magnetic resonance imaging findings of patients with Fabry disease and assess their association with future stroke risk after enzyme replacement therapy (ERT) induction. Methods- We retrospectively reviewed the magnetic resonance imaging findings of 25 patients with Fabry disease. Of these, 12 adult patients without prior stroke or ERT were enrolled to evaluate the association between baseline magnetic resonance imaging findings and stroke occurrence after ERT initiation. We assessed white matter hyperintensities, periventricular hyperintensities, and basilar artery diameter as neuroimaging markers. Results- The mean age of participants was 38.8±16.8 years. Fourteen patients (56.0%) were women. White matter hyperintensities and periventricular hyperintensities were observed in 15 and 13 cases, respectively. The mean basilar artery diameter was 3.2±0.55 mm. Two patients demonstrated old infarct lesions. Three of 12 patients in whom ERT was initiated had symptomatic stroke after baseline magnetic resonance imaging. Of these, 2 developed stroke within 6-month post-ERT initiation. The baseline basilar artery diameter was larger in patients who developed stroke than in those who did not (4.0±0.40 versus 2.9±0.49 mm, P=0.02). Conclusions- Basilar artery diameter may be associated with stroke risk after ERT initiation among Japanese patients with Fabry disease.
