摘　　要：目的　探讨儿童颅骨膜血窦的影像学表现,以提高对本病的认识。资料与方法　回顾性分析8例儿童颅骨膜血窦的临床资料和CT、MRI表现。结果　颅骨膜血窦的特征性临床症状为随颅内压改变而变化的头皮肿块。病变位于颅顶部4例,额部2例,颞部1例,枕部1例。CT表现为颅板外头皮下软组织肿块,增强后呈明显均匀强化。骨窗及三维成像可显示颅骨的孔状缺损。MRI表现为头皮下肿块,T1WI为等信号,T2 WI为高信号。并清晰显示异常连接静脉。结论　儿童颅骨膜血窦具有典型的CT、MRI表现,结合患者特征性临床表现,对该病能作出明确诊断。Objective To evaluate CT or MRI in the diagnosis of sinus pericranii in Children.Materials and Methods Clinical materials and CT or/and MRI imaging data of 8 patients with sinus pericranii were reviewed retrospectively. Results The main clinical feature of the sinus pericranii was soft mass in the scalp, it was responded in the size to the change of the intracranial pressure. CT showed the scalp soft tissue mass over the region of the sinuses, after contrast it was obviously enhanced, and was often associated with an underlying bony defect of the calvaria. Mass was shown as isointense in T 1WI, hyperintense in T 2WI with abnormal junction vein.Conclusion The sinus pericranii has typical imaging manifestation, combined with the clinical features, correct diagnosis can be made.
