RETRACTED: A case report of Morvan syndrome (Retracted Article)

Authors describe the case of a 22-year-old Caucasian male who presented acutely with psychomotor agitation, insomnia and muscle twitching with painful cramps. Autonomic symptoms were as well present, with profuse sweating, blood pressure fluctuations and tachycardia. He presented a miliary rash in his left forearm as well as in the neck. Electromyography documented myokymic movements bilaterally at both gastrocnemii and pretibial muscles. Brain imaging had no abnormalities, and anti-LGI1 and anti-CASPR2 resulted positive; this data together with electrophysiological findings suggested a Morvan syndrome. High-dose steroid therapy and plasma exchange improved substantially the clinical picture of the patient.
