The overall diagnostic accuracies of EUS and US for small PLGs were 80.9% and 63.9% （P 〈 0.05）, respectively. EUS correctly distinguished 12 （63.2%） of 19 neoplastic PLGs but was less accurate for polyps less than 1.0 cm （4/10, 40%） than for polyps greater than 1.0 cm （8/9, 88.9%） （P = 0.02）.CONCLUSION： Although EUS was more accurate than US, its accuracy for differentiating neoplastic from non-neoplastic PLGs less than 1.0 cm was low. Thus, EUS alone is not sufficient for determining a treatment strategy for PLGs of less than 1.0 cm.展开更多

We reported a case of non-traumatic MOC occurred at the elbowjoint in a 9-year old child and it has been excised by surgery. After 18 months follow-up, a favorable outcome has been achieved with the Broberg-Morrey score of 100. We suggest that surgical resection should be done as soon as the diagnosis is confirmed.展开更多
