[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.
