Abstract
Objective To evaluate the contribution of thin-slice CT and 2D-CT for diagnosis of bone cyst adjacent to joint. Methods Thirty-eight patients with pathologically proved bone cyst adjacent to joint were enrolled in this study. Slice CT scan was performed in all 38 patients. CT scan included site of bone lesion and adjacent joint. The slice thick was 1.25 mm, and distance between slice was 2.5 mm. Sagittal and coronary view were reconstructed in 15 patients for detecting the communication between bone cyst and adjacent joint. Results Of the 38 patients, 30 had solitary lesion, and 8 had multiple lesions. The lesion was underneath the cartilage of joint, low density, round or irregular in shape, with scle-rosing edge (appeared as a high density zone) in 30 cases and partial sclerosing edge in 8 cases. Break in cortex was seen on joint surface in 24 cases. No soft tissue mass and periosteal reaction was seen. Of the 15 cases had sagittal and coronary view reconstructed, all showed communication between bone cyst lesion and adjacent joint. Conclusions Thin-slice CT and 2D-CT could demonstrate the site, shape, edge, break of cortex of joint surface and communication between bone cyst and adjacent joint, and is valuable for the diagnosis of bone cyst adjacent to joint.关键词
