Abstract

RIBEIRO, S. A.; OLIVEIRA-SOUZA, R.  and  ALVARENGA, H.. Bonnet syndrome and posterior parasagittal tumor: clues to neural, mechanisms. Arq. Neuro-Psiquiatr. [online]. 1989, vol.47, n.2, pp.230-234. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X1989000200016.

A case of Bonnet syndrome associated with blindness due to bilateral eye disease and a posterior parasagittal meningioma is reported. It is assumed that visual afferent deprivation alone is not enough to produce the syndrome and that, in most instances, a 'cerebral factor' must be operative if hallucinoses are to occur. The distinction between hallucinosis and hallucinations is favored and a common neural circuit for the mediation of hallucinotic imageries in general is suggested. One should not immediately put the blame on obvious eye or visual pathways affections when facing cases of Bonnet syndrome, as they are not likely to explain the complex array of images perceived by any given patient. On the contrary, the possibility of a clinically covert intracranial disease should be always raised and intensively looked for.
