Introduction: Wallenberg syndrome is a neurological alter syndrome resulting from posterolateral involvement of the medulla oblongata. It is initially manifested by an inaugural vertigo. Observation: This is a 65-year-old patient with type II diabetes who consulted us following the development of a right hemiplegia with vertigo, dysphagia, dysphonia and facial hemiparesis. He was referred to our department for radiological exploration. Discussion: Wallenberg's syndrome or alternating sensory syndrome results from lateralized ischemic damage of the medulla oblongata. The inaugural picture is dominated by vertigo, headache and balance disorder. MRI is the examination of choice for the diagnosis of lateral bulbar infarction. It detects the lesion whatever its size. CT scan fails most of the time in the diagnosis of Wallenberg syndrome. It is performed in order to eliminate a hemorrhage in an emergency context. Conclusion: The brainstem is a very complex anatomical structure. It can be the site of minimal infarction with a spectacular clinical translation. Imaging, especially magnetic resonance imaging, has revolutionized the diagnosis and management of these lesions.
