摘　　要：目的：探讨额骨内板增生症（HFI）的 CT 表现及其发病率、病因和临床意义。方法回顾性分析243例 HFI 的 CT 表现。根据额骨内板的最大厚度将 HFI 分为4度：Ⅰ度,2.8-6.0 mm；Ⅱ度,6.1-10.0 mm；Ⅲ度,10.1-14.0 mm；Ⅳ度,〉14.1 mm。根据额骨内板增生方向将 HFI 分为内增生型、外增生型和中间型3型。结果243例 HFI 均见额骨内板增生肥厚,厚度为2.93-14.64 mm,其中Ⅰ度68例（28.0%）,Ⅱ度71例（29.2%）,Ⅲ度69例（28.4%）,Ⅳ度35例（14.4%）；内增生型82例（33.7%）,外增生型59例（24.3%）,中间型102例（42.0%）。HFI 在绝经后女性的发病率为5.47%,其中超重和肥胖妇女发病率分别达7.14%、9.09%。结论 HFI 在绝经后女性中较为常见,其 CT 表现具有特征性。Objective To explore the CT manifestations,incidence,etiology and clinical significance of hyperostosis frontalis in-terna （HFI）.Methods CT features of 243 cases HFI were analyzed retrospectively.Based on the maximum thickness of the inner table of the frontal bone,HFI was classified into 4 grades as follows：GradeⅠ─ thickness of 2.8-6.0 mm,GradeⅡ─ thickeness of 6.1-10.0 mm,Grade Ⅲ ─ thickness of 10.1-14.0 mm,Grade Ⅳ ─ thickness of greater than 14.1 mm.According to the in-crassating direction,HFI was classified into inward,outward and intermediate type.Results The inner table of the frontal bone was incrassated in all cases （n=243）.The thickness ranged between 2.93 mm and 14.64 mm,including GradeⅠin 68 cases （28.0%）, GradeⅡin 71 cases （29.2%）,Grade Ⅲ in 69 cases （28.4%）and Grade Ⅳ in 35 cases （14.4%）.There were inward type in 82 ca-ses （33.7%）,outward type in 59 cases （24.3%）and intermediate type in 102 cases （42.0%）.The incidence of HFI was 5.47% in postmenopausal women,with 7.14% in overweight and 9.09% in obese women respectively.Conclusion HFI is common in the postmenopausal women,and CT manifestations of HFI are characteristic.
