Wallenberg syndrome is most commonly referred to in medical literature as Lateral Medullary Syndrome. It is also frequently known as PICA syndrome, named after the posterior inferior cerebellar artery that is typically affected during the ischemic event causing the condition. What are the common synonyms for Wallenberg syndrome? Because Wallenberg syndrome was first described by Adolf Wallenberg in 1895, it is frequently referenced by his name in clinical settings.

Wallenberg syndrome is most commonly referred to in medical literature as Lateral Medullary Syndrome. It is also frequently known as PICA syndrome, named after the posterior inferior cerebellar artery that is typically affected during the ischemic event causing the condition.
What are the common synonyms for Wallenberg syndrome?
Because Wallenberg syndrome was first described by Adolf Wallenberg in 1895, it is frequently referenced by his name in clinical settings. However, you may encounter several alternative terms in medical records or historical texts, including:
- Lateral Medullary Syndrome (the most accurate anatomical description)
- PICA Syndrome (referring to the Posterior Inferior Cerebellar Artery)
- Lateral Bulbar Syndrome
- Dorsolateral Medullary Syndrome
Why does Wallenberg syndrome have so many different names?
The existence of multiple names for Wallenberg syndrome is largely due to the evolution of medical nomenclature from eponymous naming (naming after the doctor who described it) to anatomical or physiological naming (describing exactly where the injury occurred). While "Wallenberg syndrome" honors the original clinical observation, "Lateral Medullary Syndrome" is increasingly preferred by neurologists because it provides an immediate, precise understanding of the location of the brainstem infarct.
How is the condition classified in official systems?
Standardized medical databases categorize Wallenberg syndrome to ensure consistency in research and billing. You will find it listed under the following classifications:
- ICD-10/11: Typically coded under ischemic stroke or brainstem infarction (e.g., I63.3).
- Orphanet: Listed under ORPHA:3387, identifying it as a rare neurological manifestation of vascular origin.
- OMIM: While not a single-gene disorder, it is referenced within the context of stroke and neurovascular conditions.
What is the current preferred medical terminology?
While Wallenberg syndrome remains the most recognizable term for patients and clinicians alike, modern medical documentation increasingly favors "Lateral Medullary Syndrome." This shift ensures that the diagnosis clearly communicates the anatomical site of the lesion to the entire care team, including radiologists, physical therapists, and specialists. Currently, 55 members of the DiseaseMaps.org community have shared their experiences with Wallenberg syndrome, helping to bridge the gap between these varying medical labels.
