What is Hyperostosis Frontalis Interna

Hyperostosis Frontalis Interna (HFI) is a rare medical condition characterized by the excessive thickening of the inner table of the frontal bone in the skull. It primarily affects middle-aged to elderly women, although it can also occur in men. HFI is often asymptomatic and is typically discovered incidentally during routine imaging tests or autopsies.

The exact cause of HFI remains unknown, but hormonal factors and genetic predisposition may play a role. The condition is associated with various symptoms, including headaches, visual disturbances, cognitive impairment, and changes in personality. However, these symptoms are not specific to HFI and can be attributed to other underlying conditions.

Diagnosis of HFI involves imaging techniques such as X-rays, CT scans, or MRI scans, which reveal the characteristic thickening of the frontal bone. Treatment for HFI is generally unnecessary unless symptoms are severe or progressive. In such cases, symptom management and supportive care are the primary approaches.

While HFI is a benign condition, it is important to consult with a healthcare professional for an accurate diagnosis and appropriate management of symptoms.
