Dystonia with secondary contractures: a psychogenic movement disorder mimicking its neurological counterpart

Abstract

We report the case of an 11-year-old girl presenting with a 1.5-year history of swan neck-like deformed joint contractures of both hands. A possible diagnosis was sought in a wide range of rheumatological, metabolic, and neurological disorders. After detailed diagnostic procedures to exclude an organic pathology, steps were taken to establish a psychogenic origin. She showed symptoms that were incongruent with an organic neurological disorder, for example, a paroxysmal fluctuating course, reaction to placebo, and complete remission with psychotherapy and physiotherapy. The psychosomatic evaluation revealed a highly emotional conflict. This bizarre case demonstrates that secondary contractures are by no means an exclusion criterion for a psychogenic dystonia.
