Central vertigo due to infarction of the posterior inferior cerebellar artery - Wallenberg syndrome

Vertigo is the unrealistic sensation that the objects around us are moving or a spinning sensation. It is known as "central vertigo" when the cause is in the brain. Wallenberg syndrome occurs as a result of an obstruction of the PICA artery, blocking blood supply to the lateral medulla. Smoking, hypertension, hypercholesterolemia and diabetes, etc. are all contributing factors. As well as vertigo, it is characterized by unstable gait, double vision (diplopia), difficulty swallowing, facial pain and loss of feeling. The diagnosis is clinical and by computed tomography and/or magnetic resonance imaging. Treatment of cerebral ischemia or stroke must be started as quickly as possible to try to unblock the obstructed artery. Once the symptoms have been definitively established, the therapy is based on the treatment of these symptoms.
