Hyperostosis Frontalis Interna: Its Relationship to Cerebral Atrophy
Published online by Cambridge University Press: 08 February 2018
Extract
In not a few of the recorded cases of hyperostosis frontalis interna there has been observed some degree of cortical atrophy, chiefly affecting the frontal poles, and its occurrence raises the question of its possible relationship to the osseous change.
Three alternatives may be entertained: (1) Brain atrophy is caused by the encroachment and pressure of the hyperostotic area on the surface of the brain; (2) brain atrophy is primary, the shrinkage of the frontal convolutions in some way exciting a compensatory bony overgrowth ; (3) the two processes, osseous and neural, are entirely independent of each other.
