16MSCT in the diagnosis of cartilage lesions

Objective To analyze MSCT fingdings of cartilage lesions and to evaluate the value of CT in the diagnosis of cartilage lesions.Methods MSCT diagnosis and treatment of 54 patients with a total 81 cartilage lesions were reviewed.The MSCT manifestation and differential diagnosis of cartilage lesions were discussed emphatically with the related literature.Results Altogether,54 patients were found to have cartilage lesions including thyroid cartilage fracture(n=4),thyroid cartilage destruction(n=2),cricoid cartilage fracture(n=2),cricoid cartilage destruction(n=2).At the same time,69 costal cartilage lesions in 40 patients were found,including 61 costal cartilage fracture in 38 patients and 8 costal cartilage destruction in 2 patients.The MSCT imaging of cartilage fracture showed mainly discontinuous focal high-density of cartilage with obvious or obscure malposition(100%) and interruption of calcified cartilage malposition or separation(80.33%).Soft tissue swelling around were often found.The MSCT imaging of cartilage destruction showed mainly discontinuous focal high-density of cartilage and the margins were smooth and blunt,but calcification / ossification of cartilage surface part remained in the cartilage of normal profile,malignant infiltration of cartilage can be in the form of sediment samples change,the soft swelling were often found around.Conclusion The MSCT scan not only has a hign detection rate for the cartilage lesions,but also can display the position,number,pattern and displacement clearly,which is a fast and effective approach for the cartilage destruction and fracture.
