Atypical botulism sparing palsy of extraocular muscles.

Recent studies of patients with botulism found ophthalmoplegia as a characteristic clinical sign. Here we illustrate a very rare case of atypical foodborne botulism with multiple bilateral cranial nerve palsies sparing palsy of extraocular muscles. Therefore, the classical diagnostic pentad of botulism (dry mouth, nausea, vomiting, dysphagia, diplopia, fixed dilated pupils) may be of limited sensitivity in single cases.
