Perfusion Magnetic Resonance Imaging in Transient Symptoms of Lateral Medullary Syndrome

Abstract

There were case reports of patients who had transient medullary symptoms but showed normal diffusion weighted imaging. However, there have been no reports yet concerning perfusion weighted imaging in such cases. We present two cases of patients had transient symptoms of lateral medullary syndrome. Initial diffusion and perfusion weighted imaging was obtained while the patients still had the symptoms. Brain magnetic resonance imaging showed perfusion delay in the corresponding regions, while diffusion weighted image showed negative findings. These cases suggest that perfusion weighted imaging might be helpful in diagnosing diffusion-negative lateral medullary syndrome.
