Background:

Complex auditory hallucinations have rarely been reported in cases of brainstem stroke or tumor.

Methods:

Case study.

Results:

A patient with acute Listeria rhombencephalitis complained of formed musical auditory hallucinations on the side of recent sensorineural deafness. MRI revealed an abscess in the middle cerebellar peduncule with extensive surrounding edema.

Conclusion:

Disruption of brainstem auditory pathways may cause complex auditory hallucinations. Potential pathogenetic mechanisms are discussed and a diagnostic approach is proposed.

Résumé:

RÉSUMÉ: Introduction:

Des hallucinations auditives complexes ont rarement été rapportées dans les cas d'accidents vasculaires cérébraux ou de tumeurs du tronc cérébral.

Méthode:

Observation clinique.

Résultats:

Un patient porteur d'une infection aiguë à Listeria rhombencephalitis s'est plaint d'hallucinations auditives musicales du côté d'une surdité de perception d'apparition récente. La RMN a monté un abcès dans le pédoncule cérébral moyen avec un oedème environnant important.

Conclusions:

La perturbation des voies auditives au niveau du tronc cérébral peut causer des hallucinations auditives complexes. Nous discutons des mécanismes pathogéniques potentiels et nous proposons une approche diagnostique.
