[[1829]]-[[1831]]

In his serially published atlas of pathology, Anatomie Pathologique du Corps Humain (1829-1842), French anatomist and pathologist Jean Cruveilhier (1791-1874) provided an early clinical-pathologic description of [[Dyke-Davidoff-Masson syndrome]]. Cruveilhier's case was initially published around [[1830]], more than a century before the clinical and radiologic report of Dyke and colleagues in 1933 based on a series of patients studied with [[pneumoencephalography]]. Although Dyke and colleagues were apparently unaware of Cruveilhier's prior description, Cruveilhier's case manifested all of the key osseous and neuropathological features of Dyke-Davidoff-Masson syndrome as later elaborated by Dyke and colleagues: (1) cerebral hemi[[atrophy]] with ex vacuo dilation of the [[lateral ventricle]], (2) ipsilateral thickening of the [[diploë]] of the [[skull]], and (3) ipsilateral hyper-[[pneumatization]] of the [[frontal sinus]]es. In addition, Cruveilhier noted crossed cerebral-[[cerebellar atrophy]] in his case and correctly inferred a "crossed effect" between the involved cerebral [[hemisphere]] and the contralateral [[cerebellum]]. Cruveilhier's pathological case from 1830 clearly anticipated both the cases reported more than a century later by Dyke and colleagues based on pneumoencephalography and the more recent [[case report]]s recognized with [[computed tomography]] or [[magnetic resonance imaging]]
