Abstract
dc.description.abstract
Paradoxical vocal cord motion or vocal cord dysfunction is a descriptive term
for an inappropriate adduction of the vocal cords during respiration, which can
cause respiratory obstruction and stridor. It is associated with psychiatric conditions
in the great majority of cases. We report a 23 year-old high performance
female athlete, referred for a recurrent bilateral paralysis of the vocal cords, with
a history of four intensive care unit admissions for severe dyspnea and stridor,
which were treated several times with intubation and with tracheostomy on
two occasions. Myasthenia gravis was suspected and she was treated with pyridostigmine
and prednisone. She was discharged but despite the treatment, she
presented new episodes of stridor and was readmitted six months later. This time
the pharmacological treatment was suspended. The neurological study disclosed
a normal brain magnetic resonance, normal cerebrospinal fluid analysis and a
normal electromyography. A conversion disorder was suspected and the patient
was successfully treated with psychotherapy.
