Hyperostosis frontalis interna
| Classification according to ICD-10 | |
|---|---|
| M85.2 | Hyperostosis of the skull |
| ICD-10 online (WHO version 2019) | |
The hyperostosis frontal interna is a common, benign thickening of the calvarium in the area of the frontal bone to the inside. The hyperostosis is found predominantly in women during and after menopause and is usually asymptomatic . It is usually discovered as a chance finding during an X-ray or computed tomography of the skull.
The demarcation in the X-ray examination to other diseases such as B. Bone metastases or Paget's disease are usually easy to achieve due to the symmetrical distribution, the typical expansion purely frontal and only inward, as well as the purely hyperostotic and non- destructive character.
A common occurrence with obesity , hirsutism and headache is due to a disorder in the diencephalon and is known as Morgagni syndrome (also "diabetes of bearded women"), Stewart-Morel-Morgagni syndrome or Morgagni trias.
