We report an 11-year-old boy with a sinus pericranii. Magnetic resonance images demonstrated a small hole in the cranium underneath the subcutaneous mass. Magnetic resonance angiography (MRA) with sequential two-dimensional time-of-flight (2D-TOF) method demonstrated that the venous flow via the sinus pericranii was directed from the intra- to the extracranial venous system (the drainer type). This was confirmed by a combination of conventional cerebral angiography and percutaneous sinography. We advocate that both the correct diagnosis and classification of sinus pericranii can be established with a combination of current noninvasive neuroradiologic studies, especially for the pediatric age group. MRA with the 2D-TOF method is useful in the assessment of this venous anomaly.
我们报告一名患有颅骨膜窦的11岁男孩。磁共振成像显示皮下肿块下方颅骨有一个小孔。采用连续二维时间飞跃（2D-TOF）法的磁共振血管造影（MRA）显示，通过颅骨膜窦的静脉血流是从颅内静脉系统流向颅外静脉系统（引流型）。传统脑血管造影和经皮窦造影相结合证实了这一点。我们主张，结合当前的无创神经放射学研究可以对颅骨膜窦进行正确的诊断和分类，特别是对于儿童年龄组。采用2D-TOF法的MRA在评估这种静脉异常方面很有用。
