Midline scalp lesions are frequent in children. They include soft-tissue masses and atretic meningocoeles. Their recognition is important as their treatment differs. Intracranial venous anomalies are known to be associated with atretic cephalocoeles.
A retrospective study was undertaken to assess the frequency of intracranial venous anomalies associated with atretic meningocoeles (AT). Thirty-one patients with AT were studied by MRI. There were 13 meningocoeles and 14 encephalocoeles; 4 have not yet received surgery.
Venous anomalies were found when the cephalocoeles lay above the torcular. They include absence of the straight sinus and duplication of the longitudinal sinus.
Venous anomalies are frequent in atretic cephalocoeles and are part of the dysraphic state.
中线头皮病变在儿童中很常见。它们包括软组织肿块和闭锁性脑脊膜膨出。由于其治疗方法不同，对它们的识别很重要。已知颅内静脉异常与闭锁性脑膨出有关。
进行一项回顾性研究以评估与闭锁性脑脊膜膨出（AT）相关的颅内静脉异常的发生率。对31例AT患者进行了MRI研究。其中有13例脑脊膜膨出和14例脑膨出；4例尚未接受手术。
当脑膨出位于窦汇上方时发现静脉异常。它们包括直窦缺如和纵窦重复。
静脉异常在闭锁性脑膨出中很常见，是发育不全状态的一部分。
