Sinus pericranii is a rare venous anomaly, which shows abnormal communication between the intracranial and extracranial venous systems. Sonograms of sinus pericranii in 4 children were retrospectively reviewed to evaluate the following imaging findings: the overall sonographic appearance, change in size and shape, Doppler flow pattern, and associated anomalies. All 4 patients had irregularly shaped anechoic lesions with lobulating and bulging contours. They all showed intracranial and extracranial venous communication through a calvarial defect. Two patients had changes in the sizes and shapes of the lesions, and 2 patients had bidirectional turbulent flow on Doppler images. Two patients had isolated sinus pericranii, and the other 2 were associated with Crouzon syndrome. By identifying a venous scalp mass with intracranial and extracranial venous communication and changes in its size, shape, and venous flow pattern, radiologists will be able to make a definitive diagnosis of sinus pericranii by using gray scale and Doppler sonography.
颅骨膜窦是一种罕见的静脉异常，表现为颅内和颅外静脉系统之间的异常交通。回顾性分析4例儿童颅骨膜窦的超声图像，以评估以下影像学表现：整体超声表现、大小和形状变化、多普勒血流模式及相关异常。所有4例患者均有轮廓呈分叶状和膨出的不规则形无回声病变。他们均显示通过颅骨缺损存在颅内和颅外静脉交通。2例患者病变大小和形状有变化，2例患者在多普勒图像上有双向湍流。2例患者为孤立性颅骨膜窦，另外2例与克鲁宗综合征相关。通过识别具有颅内和颅外静脉交通且大小、形状及静脉血流模式有变化的头皮静脉肿块，放射科医生能够通过灰阶和多普勒超声对颅骨膜窦做出明确诊断。
