Fibrous dysplasia of the skull: neurological manifestations

Displasia fibrosa do crânio: manifestações neurológicas

Abstracts

The neurological manifestations of eight patients with osseous fibrous dysplasia of skull were retrospectively studied. In this series, the frontal bone was involved in 75% of the patients, the sphenoid or temporal bones in 37.5%, and the parietal in 25%. It was observed that cranial deformities occurred in all but one case, headache was present in 87.5% of the patients, visual disturbances in 50%, proptosis in 25%, and auditive symptoms in 12.5%. Six out of the eight patients were operated on: three of the four who presented progressive visual loss had postoperative improvement. In their follow up, none presented, until now, evidence of recurrence or worsening of symptoms, confirming the benign nature of fibrous dysplasia.


Foram estudados, retrospectivamente, oito pacientes com displasia fibrosa de ossos do crânio, analisando-se suas manifestações neurológicas. Na presente série, o osso frontal estava comprometido em 75% dos pacientes, o esfenóide ou o temporal em 37,5% e o parietal em 25%. Observou-se que, além das deformidades ósseas (presentes em todos os casos com exceção de um), 87,5% dos pacientes queixavam-se de cefaléia, 50% apresentavam diminuição da acuidade visual, 25% tinham proptose e em 12,5% predominavam sintomas auditivos. Dos seis pacientes submetidos a tratamento neurocirúrgico, quatro apresentavam alterações oftalmológicas progressivas, havendo melhora acentuada pós-operatória em três deles. Todos os casos foram seguidos ambulatorialmente, sem que em qualquer deles fosse observada a recidiva ou piora dos sintomas, confirmando a natureza benigna da displasia fibrosa.
