| 目的 探讨超声检查在儿童颅骨骨膜窦诊断中的临床价值。方法 回顾性分析2012年10月~2017年6月于我院行超声检查且经手术证实为颅骨骨膜窦的18例患儿病史资料，总结超声表现特征，并与CT结果对比研究。 结果 18例（100%）患儿术前二维超声均显示病变处头皮下可复性囊性肿块，探头加压肿块可消失； 13例（72%）肿块与骨膜关系密切，肿块深层骨皮质凹陷或可见缺损；16例（88.9%）肿块内可见低速静脉血流；10例（55.6%）可见病变内血供经骨皮质缺损处与颅内静脉血管相通。CT平扫18例（100%）可发现颅外软组织肿块影；15例（83.3%）骨窗可见相应部位颅骨变薄、缺损或颅骨破坏；12例（66.7%）CTA可见局部异常血管团通过板障静脉或导血管与硬脑膜静脉窦相通。结论 超声诊断颅骨骨膜窦具有较好临床实用价值，可作为本病首选的筛查影像学方法，能在术前为临床提供较可靠影像证据，诊断困难病例应结合CT检查。 |

| Abstract: |
| Objective To evaluate the effectiveness of ultrasonic diagnosis of sinus pericranii in children. Methods From October 2012 to June 2017, 18 cases of sinus pericranii confirmed by surgery were reviewed retrospectively and their ultrasonic features were analyzed，and compared with the results of CT. Results Two-dimensional ultrasound of 18 cases (100%) showed reducible cystic mass under the scalp before surgry., which disappeared with probe compression. Mass in 13 cases（72%）had a close relationship with the periosteum, and cortical depression or defect could be observed under the mass. Of 16 cases （88. 9% ）, slow velocity venous blood flow inside the mass was found. It could be observed that the blood vessels inside the mass connected to the intracranial veins through the defect of the cortex in 10 cases(55.6%). CT plain scan in 18 cases (100%) revealed extracranial soft tissue masses. Skull thinning、defect or skull destruction in 15 cases of bone window，in 12 cases (66.7%), CTA showed local abnormal vessels communicating with the dural venous sinus through the lamellar barrier vein or the conductive vessel.Conclusion Ultrasonic diagnosis of sinus pericranii was effective ,screening imaging methods as the first choice for this disease and could provide reliable imaging information before surgery. Diagnosis of difficult cases should be combined with CT examination |
