An incidental persistent falcine sinus was detected in an otherwise normal brain on MRI in a 12-year-old girl who underwent imaging after clinical suspicion of acute disseminated encephalomyelitis. The falcine sinus was associated with a hypoplastic posterior third of the superior sagittal sinus and a dominant straight sinus. Generally, atresia or hypoplasia of the straight sinus is associated with a persistent falcine sinus in postnatal life; otherwise, the falcine sinus disappears before birth. We discuss the embryological basis for such an association in this case.
一名12岁女孩因临床怀疑急性播散性脑脊髓炎而接受MRI检查，结果在其他方面正常的大脑中偶然发现了一个持续存在的大脑镰窦。该大脑镰窦与上矢状窦后三分之一发育不全及优势直窦有关。一般来说，直窦闭锁或发育不全在出生后与持续存在的大脑镰窦相关；否则，大脑镰窦在出生前就会消失。我们讨论了该病例中这种关联的胚胎学基础。
