Multimodal Sensory Distortions in Postpartum Exacerbation of Schizophrenia.

Background: Sensory distortions of body image commonly occur during migraine, seizures, nondominant cortical infarcts and hallucinogen abuse.

Methods: We report the case of a 30-year-old woman with paranoid schizophrenia presenting with postpartum onset multimodal sensory distortions in the absence of any neurological disorders or substance use.

Results: Her symptoms involved persistent facial/body metamorphopsia (distorted images) and vocal paracousis (distorted voices), in the absence of visual hallucinations, illusions or agnosia. Neuropsychological assessments revealed deficits on visual processing tasks. Neuroimaging, electroencephalography and ophthalmological evaluation revealed no abnormalities. The multimodal sensory distortions responded to antipsychotic treatment, paralleling improvement in other schizophrenia psychopathology, over a period of one month.

Conclusions: Prominent and persistent multimodal sensory distortions like metamorphopsia and paracousis in the presence of psychotic symptoms warrant a detailed neurological and general medical work-up. These symptoms presenting in the absence of neurological or substance use disorders may be a component of schizophrenia.
