There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

The osteoid osteoma was found to have a circular or oval radiolucency which was less than 2 cm in diameter with different degrees of bone sclerosis around the nidus. Of the 9 cases, 5 showed an irregular area with less density on plain X-ray film. CT scanning showed nidus in all cases. MRI showed nidus in 1 case. Radioactive scanning showed radioactive concentration in 4 cases.

Results the imaging manifestations of osteoid osteoma revealed a circular or oval radiolucency with different bone sclerosis around the nidus.the diameter ranged from 0.3cm to 1.6cm,with the average of 0.9cm.among 18 cases,only 14 cases showed nidus on plain film, all 15 cases with ct scanning showed nidus.the detection rate of nidus was 78％(14/18) for x-ray plain film and 100％(15/15) for ct, respectively.

结果 18例病灶均表现为一圆形或卵圆形的透亮区，直径0.3～1.6cm，平均0.9cm，其周围有不同程度的骨质硬化。18例x线平片仅14例显示瘤巢，15例行ct检查者均清楚显示瘤巢，x线和ct对瘤巢显示率分别为78％(14∕18)和100％(15∕15)。

All lesions were 7-12 mm in greatest diameter. Seven cases showed a round radiolucency or a thin clear sclerotic rim in middle or up-outer of femoral neck on X-ray film.

结果：8例股骨颈疝窝均为单侧单发病灶，X线平片仅显示7例，CT均表现为股骨颈前方皮质下类圆形骨质缺损，内为较均匀液体密度，边缘清楚伴有硬化缘，最大径线为7-12 mm.7例在X线平片上表现为股骨颈中轴线或其外上方的类圆形透亮区或硬化环。

Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.
