The complete resection of intracavernous sinus dermoid cysts is very difficult due to tumor tissue adherence to important anatomical structures such as the internal carotid artery (ICA), cavernous sinus, and cranial nerves. As residual dermoid cyst tissue sometimes induces symptoms and repeat surgery may be required after cyst recurrence, minimal invasiveness is an important consideration when ...

This report describes a series of patients for whom dural arteriovenous fistulae (DAVFs) of the cavernous sinus were successfully embolized using a percutaneous, transorbital technique to directly cannulate the cavernous sinus. A vascular access needle and catheter are percutaneously advanced along the inferolateral aspect of the orbit to access the cavernous sinus via the superior orbital fiss...

Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival fistula. Clival dAVFs may have a variety of potential anatomical configurations but are defined by the involvement of the venous plexus just over...

There is growing evidence to suggest that pregnancy may increase the risk of hemorrhage from cavernous malformations (CMs). In the present case, a 21-year-old primigravida was admitted to the authors' neurosurgical service after a cesarean section. Three weeks before admission she had experienced rapidly progressive bilateral lower-extremity paresthesias. Spinal magnetic resonance (MR) imaging ...

Cavernous angiomas usually occur in the parenchyma of both the supra and infratentorial compartments. At times, they can both clinically and radiologically mimic other dural-based lesions. We present a case of a patient with chronic occipital headaches, initially thought to have a meningioma, but proven to be a cavernoma with histological analysis.

A precise knowledge of the venous morphology of the carotid cavernous sinus is essential in order to choose the appropriate access routes to the cavernous sinus. The sinus is trabeculated and subdivided in compartments. Newton and Potts 1 mentioned two parts, the anterior and posterior part. The anterior receives blood from the superior ophthalmic vein (SOV), inferior ophthalmic vein (IOV), sph...

BACKGROUND Lymphangioma is a lymphatic malformation, a benign proliferation of lymph vessels. CASE We hereby present a case of eyelid lymphangioma of cavernous type in a twelve year old male patient. This is a very uncommon site for this type of lymphangioma.

conclusions if seizure occurs during the peripartum period, along with providing complete cardiovascular and respiratory support, advanced diagnostic measures are needed and cerebral venous sinus thrombosis should be considered as a possible diagnosis. introduction seizure involves less than 1% of pregnancies; however it is associated with increased maternal and fetal complications. cerebral ve...

Dural arteriovenous fistula of the cavernous sinus is usually a benign disease and rarely has brainstem edema as its complication. We present a patient with dural arteriovenous fistula of the cavernous sinus and brainstem edema. The brainstem edema resolved after embolization. Embolization should be considered first whenever brainstem edema occurs, progressive visual deterioration or increased ...

INTRODUCTION Carotico cavernous sinus fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus and is classified angiographically as dural or direct. Spontaneous CCF is a dural arterio-venous fistula at the cavernous sinus which is different from traumatic CCF or CCF associated with a ruptured aneurysm at the cavernous internal carotid artery. Cerebral angio...
