摘 要: | 目的探讨非管状骨骨肉瘤的X线平片、CT和MRI表现。方法对经病理证实的18例发生在非管状骨的骨肉瘤影像学资料进行回顾性分析。11例行X线平片检查,10例行CT检查,9例行MRI检查。结果原发性骨肉瘤15例,继发性骨肉瘤3例(其中1例继发于鼻咽癌放疗后,1例继发于骨软骨瘤术后,1例为骨化性纤维瘤局部骨肉瘤变)。发病年龄从19岁-64岁,平均43.3岁。表现为溶骨型11例,混合型5例,成骨型2例,出现软组织肿块17例,出现瘤骨16例。结论发生在非管状骨的骨肉瘤患者以中老年人多见,影像学上以溶骨型多见,平片结合CT和MRI检查有助于本病的诊断与鉴别诊断。

Abstract: | Objective To analyze the imaging features and the diagnostic value of X-ray, CT and MRI of osteosarcoma in non-tubiform bone. Methods A total of 18 cases of osteosarcoma of non-tubiform bone proved by pathology were reviewed retrospectively. Eleven cases underwent X-ray, ten cases underwent CT and nine cases underwent MRI. Results Fifteen cases were primary osteosarcoma, three cases were secondary osteosarcoma(1 case was radiation-induced osteosarcoma, 1 case was secondary to postoperative osteochondroma, and 1 case was local cancerated into osteosarcoma from ossifying fibroma). The mean age was 43.3 years(range:19-64 years). Eleven cases were osteolytic lesions, with 5 cases were mixed and 2 cases were osteoblastic. Soft tissue extension were present in 17 cases, and osteoid tumor matrix mineralization were present in 16 cases. Conclusion Most osteosarcoma of non-tubiform bone occurred in older persons. Frequently the lesions were osteolytic in imagine. Combined imaging modalities of X-ray, CT and MRI can help to diagnose and differentiate this lesion. |
