Misdiagnosis of conversion disorders.

Abstract

Five cases are presented describing the clinical features for which they were referred and admitted to a rehabilitation unit and later identified as having been misdiagnosed as having a conversion disorder. The diagnoses were sarcoma-induced osteomalacia, cerebellar medulloblastoma, Huntington's chorea, transverse myelitis, and lower extremity dystonia. A perceived history of psychological difficulties, an unusual neurologic presentation, and normal initial diagnostic testing in a female patient were associated with a misdiagnosis of conversion disorders; unfortunately, these factors also characterize actual conversion disorders.
