An OCD patient presenting with a cerebellum venous variant in a family with a strong schizophrenia loading: A case report

The role of cerebellar pathology in psychiatric symptoms has long been recognized. Cerebellar pathology has been associated with obsessivecompulsive disorder pathophysiology, particularly with compulsive hoarding. Likewise, some cerebellum abnormalities have been described in schizophrenia, as well as in comorbidity between obsessivecompulsive disorder and schizophrenia. The authors report the case of a 32-year-old woman with obsessive-compulsive disorder and a cerebellum development variant in a family with a strong schizophrenia loading. This case emphasizes the probable role of the cerebellum in the pathophysiology of both obsessivecompulsive disorder and schizophrenia, and reconsiders the existence of a so called schizoobsessive subtype of schizophrenia.
