Research progress of atypical imaging findings of bone metastasis in lung cancer

摘要:

肺癌是全球范围内癌症相关死亡的主要原因，死亡率极高，其预后差与易转移的特点直接相关，转移是肺癌进入晚期的重要标志。骨骼系统是肺癌常见的转移部位。肺癌骨转移影像学表现不典型时，容易漏诊、误诊。肺癌骨转移不典型影像学表现主要包括部位不典型和影像学表现不典型。本文对肺癌骨转移不典型影像学表现的方式、影像学表现、诊断、影像学不足进行了总结，并对新技术进行了展望，以期提高对肺癌骨转移不典型影像学表现的认识，提高肺癌骨转移影像学诊断准确率。

Abstract:

Lung cancer is one of the most common causes leading to cancer-related death worldwide with high mortality, and its poor prognosis is directly related to tendency of metastasis, but in other word metastasis is an important sign of advanced lung cancer. Although skeletal system is common metastatic site of lung cancer, the delayed diagnosis or misdiagnosis likely happen if the imaging findings of bone metastasis in lung cancer is atypical, including unusual radiographic presentation and rare site. In this review, the imaging patterns and pitfalls of the atypical presentation of lung cancer metastasis to bone were summarized, additionally a prospect about new techniques was made in order to improve our knowledge of the atypical imaging findings of bone metastasis in lung cancer and improve the early cor- rect diagnosis.
