Abstract

An olfactory paranoid syndrome of own body smell is a rare syndrome. From the psychopathological point of view the syndrome was historically classified as the subtype of delusional disorder, social phobia, dysmorphophobia or OCD.

Methods: Two psychiatrists have assessed 39-year old woman suffering from an olfactory paranoid syndrome of own body smell for 16 years. The diagnosis of delusional disorder was established (ICD-10).

The woman was assessed with 18FDG PET. The assessment was compared with 9 mentally healthy women.

Image analysis was performed using Statistical Parametric Mapping 99 (SPM99). Results: SPM group analysis revealed decreased 18FDG uptake in the right insula - BA 13 and the left medial superior temporal gyrus BA 21 (p # 0,05) and increased uptake in the right precentral gyrus BA 21 (p # 0,05).

Discussion: The revealed abnormities in temporal lobes and precentral gyrus are close to the neurobiological correlates for psychotic disorders, and therefore the PET imaging supports establis
