Background: The clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle are not clear. Objectives: To investigate the clinical and imaging presentations of primary tumors and tumor-like lesions in the clavicle for better diagnosis. Results: Eighty-one patients with clavicular diseases were identified including 49 males and 32 females with an age range of 2 - 76 years (mean, 42.6). There were malignant tumors in 50 cases (61.7%), intermediate in 12 (14.8%), and benign in 19 cases (23.5%). Malignant tumors included metastatic tumors in 31 cases (38.3%), plasma-cell myeloma in ten (12.3%), and osteosarcoma in four (4.9%). The intermediate bone tumors were mainly eosinophilic granuloma in six cases (7.4%), and aneurysmal bone cyst in three (3.7%). Benign tumors were mainly osteochondroma (6.2%), bone cyst (3.7%), and chondroma (3.7%). Malignant tumors had bone destruction, periosteal reaction, ill-defined margins and soft tissue masses. Benign tumors and tumor-like lesions had well-defined margins. Conclusion: Many tumors may occur at the clavicle with more malignant than benign tumors with no specific imaging features in most lesions. A lesion near the sternal end with atypical benign imaging features should be considered as malignant.
