Neuromyotonia masquerading as tetanus.
Neuromyotonia, or Isaac's syndrome, is a rare neuromuscular disorder of peripheral nerve hyperexcitability characterized by muscle stiffness, muscle hypertrophy, pseudomyotonia, myokymia and electromyographic evidence of myokymic or neuromyotonic discharges. A young boy with neuromyotonia is presented who was diagnosed with tetanus for severe muscle spasms, trismus and ophisthotonos. We discuss differentiation of neuromyotonia from tetanus and other disorders with similar features on clinical and electrophysiological examination.
