Pericytes are known to play critical roles in vascular development and homeostasis. However, the distribution of cavernous pericytes and their roles in penile erection is unclear. Herein we report that the pericytes are abundantly distributed in microvessels of the subtunical area and dorsal nerve bundle of mice, followed by dorsal vein and cavernous sinusoids. We further confirmed the presence...

The Tolosa-Hunt syndrome consists of painful ophthalmoplegia caused by cavernous sinus inflammation, which is responsive to steroid therapy. The MR features of 11 patients with the clinical diagnosis of Tolosa-Hunt syndrome were studied. Two patients had normal MR studies of the orbit and cavernous sinuses. In nine patients, abnormal signal and/or mass lesions were seen in the cavernous sinuses...

INTRODUCTION A case of communicating carotid-cavernous sinus fistula (CCF) after minor closed head injury is presented. CASE PRESENTATION A 45-year-old Caucasian male presented to the emergency department of a tertiary care hospital with the chief complaint of blurred vision and facial numbness. The patient had experienced a minor head injury 1 month ago with loss of consciousness. After a 2-...

Carotid-cavernous fistulas may be classified into: (1) internal carotid, (2) external carotid, or (3) a combination of both. They may result from traumatic or spontaneous rupture of the carotid artery into the cavernous sinus. Intravascular embolization has become the treatment of choice for the management of carotid cavernous fistulas. The authors report the delayed effects after the treatment...

OBJECTIVE Carotid-cavernous fistulae (CCFs) are abnormal communications between the carotid artery and cavernous sinus that may present with rapid visual deterioration and extraocular paresis as a result of increasing intraocular pressure requiring emergent treatment to preserve vision. We present a technique of balloon-assisted ethanol embolization of the cavernous carotid artery supply to ind...

Cerebral cavernous malformation with giant cysts is rare and literature descriptions of its clinical features are few. In this case study, the authors describe the clinical symptoms, radiological findings, and pathological diagnosis of cerebral cavernous malformations with giant cysts, reviewing the relevant literature to clearly differentiate this from other disease entities. The authors prese...

The endovascular treatment of spontaneous dural cavernous sinus fistula (DAVF) can be accomplished by arterial approach, just with symptoms relief, or by numerous venous approaches through the inferior petrosal sinus, ophthalmic vein, anterior or posterior intercavernous sinus and facial vein. Our case suggests the approach to the cavernous sinus via the foramen ovale and emissary veins punctur...

Pure epidural cavernous hemangiomas are quite rare. In this paper, a case of lumbar epidural cavernous hemangioma presenting as a lumbar radiculopathy is presented. The magnetic resonance imaging findings, differential diagnosis and therapy options of this rare case are discussed.

PURPOSE Cavernous sinus surgery is considered neurosurgically feasible. A systematic review of patients undergoing cavernous sinus procedures for meningioma was undertaken to determine whether cavernous sinus surgery could be performed with an acceptable level of iatrogenic-induced dysfunction. METHODS Fifty-six patients undergoing 57 cavernous sinus surgical procedures performed by a single ...

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...
