Superior petrosal sinus (SPS) dural arteriovenous fistula (DAVF) is one of tentorial DAVFs with significant morbidity, which usually drains into the petrosal vein and its tributaries. Unless there is a connection with venous sinus, surgical obliteration is required. We present two cases of SPS DAVF which were successfully treated with the presigmoid retrolabyrinthine approach.

Tentorial dural arteriovenous fistula (DAVF) is a rare vascular disease, which has high risk of intracranial hemorrhage. We present two cases of tentorial DAVF which were successfully treated with single trial of transarterial embolization using Onyx. We briefly reviewed the types of the tentorial DAVF and strategies of treatment.

A case of cavernous angioma of the cerebellar vermis is described. Cevernous angioma is rare vascular malformation of the central nervous system and the cerebellar vermis is very unusual site. Exact preoperative diagnosis of this lesion is difficult because cavernous angioma is angiographically silent and generally accepted to be very rare. The relevant literature is reviewed.

The authors present a case of isolated dural arteriovenous fistula (DAVF) in the transverse sinus, which developed six years after microvascular decompression caused by hemifacial spasm via suboccipital craniectomy. The lesion was successfully treated by transarterial embolization using Onyx. We reviewed the related radiologic and therapeutic features of DAVF involving an isolated sinus and described the feasibility of the use of Onyx.

A case of extradural cavernous hemangioma on lumbar spine combined with ruptured disc is reported. Cavernous hemangiomas are uncommon vascular malformation of the central nervous system. In the spine, the majority of these lesions are from secondary extensions of vertebral hemangiomas. Occurrence of a primary extradural cavernous hemangioma is relatively rare. Authors report a case of extradural cavernous hemangioma of the spine with the review of literatures.

Transvenous coil embolization has been successfully applied for the treatment of cerebral dural arteriovenous fistulae. Unfortunately, the technique can not be applied in cases of poor or absent venous access route to the fistula, the situation of which is not uncommon. Transarterial embolization can be performed as an alternative method. However, the method usually ended in partial embolization of the fistulae because of the multiplicity of the dural feeders and anfractuosity of the feeders. Use of liquid embolic material, such as glue in transarterial embolization generally regarded as not conventional. Recently we experienced a successful embolization using a newly introduced liquid embolic material, Onyx in a case of transverse-sigmoid sinus dural arteriovenous fistula which was failed to be embolized with transvenous approach.
