Neuroimages of persistent falcine sinus in children.

Case 1 A 14-year-old girl with a known diagnosis of systemic lupus erythematosus came to our department with the initial complaint of headache. Brain MRI revealed a normal brain parenchyma in all sequences. In addition, an incidental falcine sinus was observed in its entire length in sagittal images (Fig. 1A). The sinus connected the junction of the middle and posterior thirds of the superior sagittal sinus with the origin of the straight sinus. The straight sinus was also seen (Fig. 1B, 1C). MR venography confi rmed the presence of the persistent falcine sinus with the straight sinus (Fig. 1D).
