Endocranial hyperostosis in Sangiran 2, Gibraltar 1, and Shanidar 5.

Sangiran hominid 2 (S-2), Gibraltar hominid 1 (G-1), and Shanidar hominid 5 (SH-5) exhibit previously undescribed bilateral, paramedian hyperostosis of the endocranial frontal squama that spares the frontal crest, sagittal sinus, and ectocranial surface. The hyperostosis is localized to the frontal (usually the middle third) and parietal and is consistent with a diagnosis of hyperostosis calvaria interna (HCI), inclusive of hyperostosis frontalis interna. The hyperostosis in these specimens is compared to fossil hominids from Indonesia and Europe and to modern human cases of HCI. The three cases of HCI reported here documented the existence and frequency of HCI in fossil hominids and push the antiquity of the disease back to nearly 1.5 million years. The relatively great incidence of HCI in fossil hominids adds another confounding factor to the problematical issue of the taxonomic significance of cranial vault thickness.

[The Stewart-Morel syndrome in the differential diagnosis of patients with frontal headache].

Hyperostosis frontalis interna is the name generally applied to skull thickening more or less restricted to the squamous portion of the frontal bone and involving, in particular, its subdural or inner surface. The association of this calvarial thickening with virilism and obesity is a clinic-anatomic complex often know as the Morgagni's syndrome and is also referred to as the Stewart-Morel syndrome or metabolic craniopathy, when accompanied by mental disorders. Hyperostosis frontalis interna is being discussed here mainly in connection with the Stewart-Morel's syndrome of which it is the pivotal feature. Frontal headache is a common complaint and is severe in some cases. In addition various neuropsychiatric disturbances may be manifested.

Computerized tomography in typical hyperostosis cranii (THC).

THC is a remodelling process affecting the bones of the neurocranium. CT analysis shows that both the inner and the outer table as well as the diploë can be involved in this process. The term typical hyperostosis cranii (THC) replaces the terms derived from conventional radiography such as nebula frontalis, hyperostosis frontalis interna, etc., as CT shows transitional stages between them. A new type of THC is described. There are morphological similarities between THC and Paget's disease in CT.

[Significance of cranial hyperostoses for the neurologic-psychiatric practice].

The present paper attempts to comment on the relation between diffuse concentric hyperostoses of the cranial vault and neurologic and psychiatric symptoms in a male aged 42 and a woman aged 23 when death occurred. In the past, similar discussions mainly concerned the hyperostosis frontalis interna (Hfi), although the demonstration of a true relation is difficult in the Hfi because of its late occurrence at an advanced age (60-70 years), in which mental disturbances due to other pathological circumstances are frequent as well. The diffuse concentric hyperostosis in young individuals has comparatively seldom been regarded, although in young individuals the age factor in the consideration of mental disturbances can be excluded. The 42 year old male had an 18 years history of mental disturbances such as a mental change and severe episodic psychiatric symptoms, which repeatedly required clinical treatment. Since 18 years he had also suffered from headaches which caused an abusus of phenacetinum. A diffuse concentric hyperostosis of the neurocranium with a long developmental course, as could be derived from microscopical examination, was considered likely to be the reason for the longstanding headaches and the mental change. The 23 year old female was a prostitute suffering from serious headaches and neurodystonia until she died suddenly and unexpectedly, without sufficient autopsy findings. The cranial vault displayed a severe concentric hyperostosis besides other striking changes.
