Recurrent multiple cranial nerve palsies.

The material for this paper comprises four case reports, which must necessarily be presented in some detail, having regard to the points in which they resemble and differ from one another. The resemblance between these cases is close enough to suggest that they constitute a recognizable clinical syndrome. As to their aetiology, the data permit no definite conclusion but suggest the possibility of a hypersensitivity reaction as a common factor.
