| Popis: | The falcine sinus (FS) is a normal embryonic venous channel that is situated between the two layers of the falx cerebri. It connects the posterior part of the vein of Galen with the superior sagittal sinus (SSS) during fetal life and is rarely seen after birth. Association of persistent FS with SSS occlusion in postnatal life has been reported.1–3 However, in these reports, it is not clear whether the FS had recanalized following the sinus occlusion or was existent prior to the occlusion. We report the imaging findings in a child with SSS thrombosis, where serial MRI studies revealed recanalization of the FS, and its consequent obliteration following recanalization of the SSS. ### Case report. A 12-year-old boy presented with history of headache and two episodes of focal seizures, 6 days after he received l-asparaginase for treatment of acute lymphoblastic leukemia. Clinical examination was unremarkable except for the presence of bilateral papilledema. He did not have any neurologic symptoms prior to this episode of illness and had normal neurologic development. MRI of the brain revealed foci of T2 hyperintensity in the precentral and postcentral gyri on either side. Two-dimensional time-of-flight MR venography revealed thrombosis of the entire length of the SSS and … |
