OBJECTIVE
The purpose of this study was to compare magnetic resonance (MR) imaging and surgical observations of fluid in simple bone cysts.
STUDY DESIGN
Findings during MR imaging of 7 simple bone cysts were compared with surgical observations 1 day or 1.8 months (mean) after MR imaging.
RESULTS
All MR images showed cavities filled with fluid. In 2 patients operated on the day after the imaging, surgical observations were in accordance with the MR findings. At surgery 1.8 months after the MR examination, 4 cavities were found to be empty and 1 cavity contained only a minor amount of fluid.
CONCLUSION
A discrepancy between MR imaging and surgical observations of fluid in simple bone cyst cavities was observed that might be dependent on the time between the observations, indicating that a fairly rapid absorption of fluid might occur or that the amount of fluid in a simple bone cyst can vary for unknown reasons.
目的
本研究旨在比较单纯性骨囊肿内液体的磁共振（MR）成像与手术观察结果。
研究设计
对7个单纯性骨囊肿的MR成像结果与成像后1天或1.8个月（平均）后的手术观察结果进行比较。
结果
所有MR图像均显示囊肿内充满液体。在成像后第二天接受手术的2例患者中，手术观察结果与MR表现一致。在MR检查后1.8个月进行手术时，发现4个囊肿为空的，1个囊肿仅含有少量液体。
结论
观察到单纯性骨囊肿内液体的MR成像与手术观察结果存在差异，这可能取决于观察之间的时间间隔，表明液体可能会相当快速地吸收，或者单纯性骨囊肿内的液体量可能因未知原因而有所变化。
