摘　　要：目的探讨颅骨骨膜窦的影像学特征表现,提高对该病的认识和诊断正确率.方法回顾性分析2例具有完整CT、MR扫描资料并经临床证实的颅骨骨膜窦病例,分析其影像学表现.结果2例病灶均位于右顶部中线旁,CT表现为颅板外头皮下软组织肿块,局部颅骨受压并可见孔状缺损与颅内相通;MR表现为头皮下肿块,T1WI序列呈等信号,T2WI序列呈高信号,增强扫描延迟期病变明显强化.结论颅骨骨膜窦具有典型的影像学特征,结合特征性的临床表现,对该病能作出正确诊断.Objective To investigate the imaging feature of sinus pericranii,and to improve the diagnosis ability of the disease.Methods CT and MR finding of 2 patients clinically proven with sinus pericranii were analyzed retrospectively,the radiologic manifestations were analyzed.Results The lesions were adjacent to the midline of the right skull in 2 patients.CT showed the scalp soft tissue mass over the region of the sinuses,and skull defects were seen adjacent to masses,and was often associated with an underlying bony defect of the calvaria.MRI scan suggested uniform T1WI signal,and slight increased in T2WI signal,time delayed enhancement scan showed it was obviously enhanced.Conclusion The sinus pericranii has typical imaging manifestation,combined with the characteristic clinical features,the correct diagnosis can be made.
