Wallenberg Syndrome - Lateral Medullary Syndrome

DWI (b1000) image shows restricted diffusion indicating right sided dorsal lateral medulla oblongata infarct. Corresponding ADC map image shows low signal and axial T2 and coronal FLAIR show high signal in this Posterior Inferior Cerebellar Artery (PICA) territory infarct. This case shows how sensitive is MRI in detecting even little infarcts. Also the eponym is worth noting in case of exams ;).
