Hyperostosis frontalis interna (HFI) is characterized by excess growth of the frontal bone. Although the exact cause of HFI is not known, it has been found to be associated with increased age, prolonged estrogen stimulation and elevated leptin. Literature shows its association with seizure, dementia, obesity, headache and endocrine abnormalities. HFI may be syndromic and non-syndromic. Timely identification of HFI can prevent unnecessary diagnostic tests. We report a case of non-syndromic HFI in an elderly female who presented with headache.
