骨纤维异常增殖症的影像诊断(附31例报告)

目的　探讨骨纤维异常增殖症的综合影像诊断方法及其价值。方法　报告经手术病理证实的骨纤维异常增殖症 3 1例。3 1例均摄有平片 ,其中加做CT 11例 ,MRI 6例。对比讨论X线平片和CT表现。结果　 3 1例中单骨型 18例 ,多骨型 13例 ,其中骨纤合并骨巨细胞瘤和骨纤合并脑膜瘤各 1例 ,Albright综合征 1例。X线分型 :囊肿型 (18灶 ) ,弥漫型 (3 0灶 ) ,丝瓜络型 (2灶 ) ,虫噬型 (2灶 )。CT表现主要分为囊状膨胀型改变 (3 8灶 )和硬化型改变 (7灶 )。结论　骨纤的影像诊断目前仍以X线平片为主 ,颅面部的病变则CT占优 ,两者结合对大部分骨纤可做出正确的诊断

Imaging Diagnosis of Fibrous Dysplasia(A Report of 31 Cases)

Objective To study the imaging diagnostic methods of fibrous dysplasia.Methods 31 patients with fibrous dysplasia proved pathologically were studied. In addition to CT scan in 11 cases and MRI in 6 cases,plain films were performed in all 31 cases. The compartive analysis was made between the features of plain film and CT.Results Of 31cases, 18 patients had monostotic fibrous dysplasia and 13 polyostotic lesions. Roentgenologically, they were divisible into 4 type: cystic type(18 lesions),diffuse type(30 lesions),sponge groud-flesh type(2 lesions) and moth-eaten type(2 lesions). CT features of lesions were classified into 2 type: cystic expanded type(38 lesions) and osteosclerotic type(7 lesions).Conclusion X-ray film should be used as the first choice in diagnosis of fibrous dysplasia. CT is hightly sensitive in displaying the craniofacial lesions.The lesions can be correctly diagnosed in most instances,if plain film combined with CT.
