(作者:___________单位: ___________邮编: ___________)
【摘要】目的分析前列腺癌骨转移的临床及影像学表现,探讨其临床及影像学特点和诊断价值。方法经病理证实的前列腺癌骨转移病例共20例,年龄43~85岁,,对其X线、CT、MRI表现进行回顾性分析。20例均做了X线平片检查,4例做了CT和MRI检查,6例做了骨核素扫描。结果在前列腺癌骨转移病例中,先发现骨转移,然后查出原发灶者16例,先发现原发灶,然后查出骨转移者4例。其中成骨型转移16例,混合型4例。结论前列腺癌属于亲骨性肿瘤,极易发生骨转移,成骨型多见。临床上以发病年龄较大,多数先发现转移病灶,后发现原发病灶为特点。影像特点:以骨盆和脊柱为主的向心性转移多见。X线、CT、MRI、核素扫描相结合对于发现和诊断本病具有重要意义和价值。

Methods The results of pathology (20/20),Xray (20/20),CT and MRI (4/20),nuclide scanning (6/20) on 20 patients with bone metastasl from prostate carcinoma were retrospective reviewed. Results The first site Of detected lesions was bone metastasis in 816 Original lesion was foand in the prostate before bone metastasis in 4 terms Of Path010gical type Of Prostate carcinoma,there were 1 6 cases with oseoteresis and 4 cases with mixed type in this study. Conclusion The bone metastasis is mon in Prostate corcinoma since its osteophilic nature,so the bone metastasis could be the first imaging fndings in some main central metastasls is located in the spine and pelvis
