[Symptomatic acoustic hallucinations after traumatic brain damage. Review of the literature and case report].

Only single cases with complex acoustic hallucinosis have been reported in the literature. A 30-year-old patient is presented who suffered from a midbrain syndrome after severe traumatic brain injury and developed an acoustic hallucinosis in the chronic stage of rehabilitation. The functional relevance and therapeutic strategies are considered with regard to the relevant literature.
