Wilsons Disease also known as hepatolenticular degeneration is a autosomal recessive disorder, characterized by abnormal copper deposition in the liver, brain, and other tissues caused by mutation in the copper transporting gene ATP7B. Patients presents with neurological and hepatic disorder. Psychiatric manifestation are common along with movement disorder but its association with paraphilic disorders like zoophilia is very rare and there is practically no literature regarding this in North-Eatern India. In this article we report the unique case of a 21 year old boy from rural Assam suffering from Wilson’s disease with multiple neuropsychiatric manifestations among which zoophilia was noteworthy. This case report highlights a rare and atypical association between an adolescent patient of Wilson disease & zoophilia--- a relatively rare paraphilic disorder. A 21 year old boy presented in the Psychiatry emergency department in a tertiary care hospital with aggressive, disorganized behavior with reported sexual act with a cow. Examination of the patient also revealed massive organomegaly and K-F ring which on further investigation confirmed the diagnosis of Wilsons Disease. The occurrence of zoophilic behavior in Wilsons disease is very rare and we have not come across any such report regarding this. To conclude, the association between copper deposition in specific brain areas due to Wilsons disease and zoophilic behaviour we need further studies with better investigative modalities, which will in turn help in drawing an individualise treatment plan.
