summary 
A patient suffering from both post-traumatic stress disorder (ptsd) and a comorbid schizoaffective disorder was treated with imaginal exposure treatment. After 26 sessions the ptsd symptoms were in full remission. This was still the case at follow-up after 12 and 24 months. Furthermore, the patient was no longer on antipsychotic medication. The case shows that ptsd can be treated successfully even if patients have a psychotic disorder. In view of the severity of both disorders it is at least worth trying imaginal exposure treatment.
