THE ASSOCIATION OF CODMAN TRIANGLE AND ACICULAR PERIOSTEAL REACTIONS WITH BENIGN AND MALIGNANT BONE DISEASES
Objective To analyze the association of Codman triangle and acicular periosteal reactions in imaging examination with benign and malignant bone diseases.Methods This study consisted of 897 patients who had periosteal reactions found in imaging examination and confirmed by pathology.The patients were divided into malignant-lesion group (n =85) and benign-lesion group (n =812) according to pathological results.The appearance of Codman triangle and acicular periosteal reactions between the two groups was compared.Results Imaging features of Codman triangle and acicular periosteal reactions were noted as follows:in the malignant group,Codman triangle was found in 43 cases (50.6%),and in the benign group,it was six cases (0.7%),the difference was significant between the two groups (x2 =360.6,P <0.01).In the malignant group,acicular periosteal reactions were observed in 30 cases (35.3%),and in the benign group,it was four (0.5%),the difference was significant (x2 =246.1,P<0.01).Conclusion Codman triangle and acicular periosteal reactions can be found both in malignant and benign bone lesions,more common in malignant tumors,but in a few cases,which can also be seen in the rapid progression of a variety of benign bone lesions.
