Conversion disorder presenting as hemiplegia and hemianesthesia with loss of neurologic reflexes: a case report.

Conversion disorders can present with a variety of sensorimotor signs and symptoms. We present the case of a young woman who presented with sudden onset hemiplegia and hemianesthesia including unilateral loss of deep tendon reflexes, Babinski reflex, and loss of rectal tone with bladder incontinence. The loss of rectal tone, loss of deep tendon reflexes, and a flaccid Babinski reflex are unusual signs in conversion disorders. A thorough medical workup including x-rays, CT scans, and magnetic resonance imaging revealed no organic causes for the neurologic deficits. Before the onset of symptoms, the patient was emotionally upset during an argument, which may have provided the psychologic stressor necessary for a conversion disorder. The young woman gradually regained full neurologic function over the next 14 hours. Conversion disorders should be considered when the neurologic findings do not correspond to known anatomic or physiologic pathways, although a thorough medical investigation must be performed to search for organic causes.
