A retrospective review of 2,851 bone scans done at a cancer center over a period of 4 yr revealed 41 patients having a single abnormality in a rib as their first abnormal scintigraphic finding. The scan findings in these cases were correlated with clinical, scintigraphic, and radiographic follow-up to ascertain their etiology and course. Four lesions (9.8%) were due to malignant disease, 16 (39%) were associated with benign fractures demonstrated on x-ray, 11 (27%) were associated with primary or postoperative radiation therapy. The remaining ten patients (24.2%) with normal x-rays and no association with radiation therapy or subsequent development of metastasis were assigned to benign etiology. This experience suggests that solitary rib lesions in cancer patients are uncommon and are most frequently (90%) associated with benign etiology.
对一家癌症中心4年内进行的2851例骨扫描进行回顾性研究发现，41例患者的首次骨闪烁显像异常表现为肋骨单发异常。将这些病例的扫描结果与临床、骨闪烁显像及放射学随访结果相关联，以确定其病因及病程。4例病变（9.8%）由恶性疾病引起，16例（39%）与X线显示的良性骨折相关，11例（27%）与原发或术后放射治疗相关。其余10例患者（24.2%）X线检查正常，与放射治疗无关且无后续转移发生，病因归为良性。该研究表明，癌症患者的孤立性肋骨病变并不常见，且最常见（90%）的病因是良性的。
