Hyperostosis frontalis interna (HFI) is a common and often incidental finding seen on imaging. There is a significant paucity of radiology literature, particularly regarding the MRI imaging appearance of HFI.
We reported two cases of HFI on MRI, which showed focal enhancement. These were stable on long-term follow-up studies and thought to be most consistent with benign enhancement.
Further studies are needed to elucidate the underlying pathogenesis; however, it is important to be aware that regions of HFI may demonstrate variable enhancement and are sometimes mistaken for osseous metastatic disease.
颅腔肥厚症（HFI）是一种常见的影像学表现，通常为偶发发现。关于 HFI 的影像学表现，放射学文献非常匮乏。
我们报告了两例 HFI 的 MRI 表现，呈局灶性强化。这些病例在长期随访研究中稳定，被认为最符合良性强化。
需要进一步研究阐明其潜在发病机制；然而，重要的是要意识到 HFI 的某些区域可能表现出不同程度的强化，有时可能被误诊为骨转移病变。
