Abstract: Pedophilia is a disorder of public concern because of its association with child sexual offense and recidivism. Previous neuroimagingstudies of potential brain abnormalities underlying pedophilic behavior, either in idiopathic or acquired (i.e., emergingfollowing brain damages) pedophilia, led to inconsistent results. This study sought to explore the neural underpinnings ofpedophilic behavior and to determine the extent to which brain alterations may be related to distinct psychopathological featuresin pedophilia. To this aim, we run a coordinate based meta-analysis on previously published papers reporting whole brainanalysis and a lesion network analysis, using brain lesions as seeds in a resting state connectivity analysis. The behavioralprofiling approach was applied to link identified regions with the corresponding psychological processes. While no consistentneuroanatomical alterations were identified in idiopathic pedophilia, the current results support that all the lesions causingacquired pedophilia are localized within a shared resting state network that included posterior midlines structures, right inferiortemporal gyrus and bilateral orbitofrontal cortex. These regions are associated with action inhibition and social cognition, abilitiesthat are consistently and severely impaired in acquired pedophiles. This study suggests that idiopathic and acquired pedophiliamay be two distinct disorders, in line with their distinctive clinical features, including age of onset, reversibility and modusoperandi. Understanding the neurobiological underpinnings of pedophilic behavior may contribute to a more comprehensivecharacterization of these individuals on a clinical ground, a pivotal step forward for the development of more efficient therapeuticrehabilitation strategies.
