A case report of hyperostosis frontalis interna identified in a gross anatomy cadaver laboratory

Hyperostosis frontalis interna (HFI) is an uncommon condition characterized by excess bone growth with multiple nodules mostly on the inner table of the frontal bone.  
We report a case of HFI in 85-year-old female identified during a routine dissection in the Faculty of Dental Sciences, University of Peradeniya. The inner table of the calvarium of the frontal bone was covered with large, irregular nodular bony thickening without internal damage to the brain. 
Although there’s a significant prevalence of HFI among general population, there are very limited research studies carried out in Sri Lankan population. Therefore, the adequate awareness about HFI, among medical professionals will help in more accurate interpretation of radiographs.
