BACKGROUND AND PURPOSE Differentiation between paraclinoid and cavernous sinus aneurysms of the internal carotid artery (ICA) is critical when considering treatment options. The purpose of this study was to determine whether contrast-enhanced (CE) 3D constructive interference in steady state (CISS) MR imaging is useful to differentiate between paraclinoid and cavernous sinus aneurysms. MATERI...

BACKGROUND AND PURPOSE Three-dimensional (3D) constructive interference in steady state (CISS) MR imaging is useful for demonstrating cranial nerves (CNs) in the cistern. The purpose of this study was to evaluate normal CNs III, IV, V1, V2, and VI in the cavernous sinuses by using contrast-enhanced, three-dimensional (3D), Fourier transformation CISS MR imaging. METHODS In 76 normal cavernous...

Posterior communicating artery (PCoA) aneurysm-cavernous sinus fistulae are an extremely rare complication of head injury . The treatment of PCoA aneurysm-cavernous sinus fistulae has not been well described. A 27-year-old man was admitted with a retroocular bruit and blurred vision of the left eye seven months after a severe head injury. We report the angiographic appearance of a posterior com...

Although usually asymptomatic, a persistent trigeminal artery (PTA) can rarely be associated with a direct fistula to the cavernous sinus (ie, trigemino-cavernous fistula). We present three patients with trigemino-cavernous fistulas; two were subsequently treated using modern endovascular techniques while the third initially declined therapy. We then review the literature of reported cases of t...

The cavernous hemangioma is the most common benign orbital tumor in adults. Its presentation is during the forth to fifth decades with a slowly progressive unilateral proptosis. Intraconal cavernous hemangiomas may be difficult to differentiate from other intraconal lesions such as schwannomas, meningiomas and hemangiopericytomas. We report a case of orbital cavernous hemangioma diagnosed by Tc...

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...

UNLABELLED Carotid-cavernous fistulas are an uncommon diseases characterized by abnormal communications between arteries and veins located in the cavernous sinus. According with Barrow´s classification they could be divided in two groups: direct and indirect. The typical symptoms showed by theses pathologies are: pulsating exophthalmos and orbital blow. The present study describes a case of dir...

Purpose We report the case of a patient with cavernous sinus syndrome associated with biopsy-confirmed metastasis from colorectal cancer. Observations A patient known for laryngeal carcinoma and metastatic colorectal carcinoma presented with symptoms of left trigeminal neuralgia and progressive, near-complete ophthalmoplegia. Magnetic resonance imaging (MRI) revealed a mass in the left cavern...

Cavernous hemangiomas that occur within the cavernous sinus (CS) are different from cerebral cavernous malformations (CMs) clinically, on imaging studies, and in their response to treatment. Moreover, CMs are true vascular malformations, whereas hemangiomas are benign vascular tumors. Because of these differences, the authors suggest that these two entities be analyzed and grouped separately. U...

Proptosis due to carotid cavernous fistula is rare sequelae of head injury. We report a case of post-traumatic, direct high flow carotid cavernous fistula that resolved spontaneously 06 weeks after carotid angiography. It however, resulted in loss of vision due to delay in early treatment. In the cases of post-traumatic proptosis, carotid cavernous fistula should be kept in mind.
