ABSTRACT
An adult female was found to have a variation of the left basal vein of Rosenthal after presenting with complaints of headache. The vein, in this case, drained directly into the confluence of sinuses instead of the great vein of Galen. Variation of the basal vein is likely due to the embryonic development of the deep cerebral venous system as primitive structures either differentiate further or regress with age. Such changes may result in the uncommon presentation seen in this case. To our knowledge, this is the first case reported of the basal vein draining into the confluence of sinuses.

Objective To investigate the treatment strategy of operation in torcular herophili meningiomas.Methods Retrospectively analyzed the treatment strategy of operation and follow-up data of 16 cases torcular herophili meningiomas patients.Results Grade Ⅰ resection was 9 cases,grade Ⅱ resection was 5 cases,grade Ⅳ resection was 2 cases.One patient appeared transverse thrombosis in postoperative.Followed up for 26-61 months,all patients had no recurrence.Conclusion By detailed preoperative evaluation,selection of appropriate operative approach,reasonable treatment of venous sinus adhesion tumor,supplemented by the necessary radiotherapy,can reduce the risk of operation and recurrence rate to torcular herophili meningiomas.
ABSTRACT
Congenital dural arteriovenous shunt (DAVS) is a rare disease entity. A neonate diagnosed to have cystic mass in posterior fossa during prenatal sonography presented with heart failure and hydrocephalus. Cerebral angiography revealed a DAVS at the torcular herophili. Successful occlusion of feeders was achieved by staged transarterial embolizations, with subsequent improvement of heart failure. Transarterial embolization could be a successful treatment method in pediatric patients with congenital DAVS, in case of limited numbered feeders.
