Abstract

RECENTLY we1 reported three cases of divergence paralysis, in all of which the condition was associated with increased intracranial pressure. In addition, the literature on divergence paralysis was reviewed. For convenience, we shall summarize this paper before presenting our further observations.

In the literature, divergence paralysis is described in the following conditions: (1) inflammatory and toxic diseases of the cerebrum,2 (2) cerebral hemorrhage,3 (3) head trauma,4 and (4) brain tumor. In the last category, seven cases were found in which the authors were able to verify the existence of a tumor of the posterior fossa either at operation or at necropsy. These seven cases were reported from four sources.5 In all cases, there was evidence of increased intracranial pressure and concurrent divergence paralysis. In three of the cases,5a the tumor was removed, and the divergence paralysis disappeared as the papilledema diminished. We reported on
