New onset of body dysmorphic disorder following frontotemporal lesion

The etiology and pathophysiology of body dysmorphic disorder (BDD) have not been delineated. The authors report a 24-year-old man who developed BDD at age 21 after an inflammatory brain process. Neuroimaging studies showed new atrophy in the frontotemporal region. The authors review cases from the literature with similar clinical features and neuroimaging findings as well as discuss the possible correlation between the neuroanatomic lesion and the clinical presentation of BDD in the patient.
