Carotid cavernous fistulae (CCF) are defined as abnormal connections between the carotid circulation and cavernous sinus. CCFs can be categorized as being direct or indirect. Direct CCFs are usually associated with trauma, whereas indirect CCFs are associated with revascularization following cavernous sinus thrombosis. We present a case of a 53-year-old male who presented with tinnitus, proptosis, conjunctivitis, and blurry vision. The patient had a recent endovascular transvenous embolization that was only partially successful, with a residual carotid cavernous fistula draining to the left superior ophthalmic vein and multiple cortical veins...

BACKGROUND: Cerebral venous thrombosis (CVT) is a potentially life-threatening underdiagnosed disease. Headache is a common but nonspecific finding in CVT. Other features such as ocular finding can assist to correct diagnosis, but their frequency in CVT has not been previously evaluated. The aim of this study is to evaluate the ocular symptoms and signs in CVT and their association with outcome. METHODS: The demographic, clinical, laboratory, radiological, and outcome data were collected and analyzed from patients referred to a tertiary hospital during 6 years...

Endoscopic endonasal transorbital approach has been described for the removal of orbital lesions located anteromedially in temporal fossa. The same has been observed to be a versatile approach to the anterior and middle cranial fossa only in laboratory studies. This is the first clinical report of combined transorbital transnasal endoscopic approach to the cavernous sinus, superior orbital fissure, and middle cranial fossa in a case of recurrent nasopharyngeal angiofibroma using the three-surgeon six-handed technique...

A carotid-cavernous fistula (CCF) is an abnormal communication between arteries and veins within the cavernous sinus and may be classified as either direct or dural. Direct CCFs are characterized by a direct connection between the internal carotid artery (ICA) and the cavernous sinus, whereas dural CCFs result from an indirect connection involving cavernous arterial branches and the cavernous sinus. Direct CCFs frequently are traumatic in origin and also may be caused by rupture of an ICA aneurysm within the cavernous sinus, Ehlers-Danlos syndrome type IV, or iatrogenic intervention...

Carotid cavernous fistula (CCF) is an abnormal vascular shunt from the carotid artery to the cavernous sinus. They are commonly classified based on hemodynamics, etiology or anatomically. Hemodynamic classification refers to whether the fistula is high or low flow. Etiology is commonly secondary to trauma or can occur spontaneously in the setting of aneurysm or medical conditions predisposing to arterial wall defects. Bilateral carotid cavernous fistulas are rare. We present a case of bilateral CCF secondary to trauma...

OBJECTIVES: Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the management of both benign and malignant tumors of the pterygopalatine fossa. METHOD: We report our experience with the endoscopic endonasal approach for the management of both benign and malignant tumors and summarize recent recommendations...

Periorbital cellulitis is an acute infection of the periorbital soft tissues with potential sight and life threatening complications that most commonly occurs in children([1]) . Post-septal abscess formation can cause loss of sight; furthermore, posterior spread of infection may progress to cavernous sinus thrombosis and intracranial infection([1, 2]) . In England April 2014-March 2015, 3687 patients attended hospital with periorbital cellulitis costing the National Health Service over £9.5 million per annum before considering the cost of treating its complications([3]) ...

Basosquamous carcinoma is a rare, highly aggressive variant of basal cell carcinoma with elevated rates of recurrence, perineural invasion, and metastasis. We describe a patient who presented with unilateral complete ophthalmoplegia, ptosis, optic neuropathy, and trigeminal neuropathy due to perineural intracranial invasion of nasal basosquamous carcinoma via the sphenopalatine fossa to the cavernous sinus, orbit, and infratemporal fossa. To our knowledge, this is the first reported case of basosquamous carcinoma with perineural invasion involving the cavernous sinus in the English language ophthalmic literature...

OBJECTIVE: Studying the three-dimensional (3D) anatomy of the cavernous sinus is essential for treating lesions in this region with skull base surgeries. Cadaver dissection is a conventional method that has insurmountable flaws with regard to understanding spatial anatomy. The authors' research aimed to build an image model of the cavernous sinus region in a virtual reality system to precisely, individually and objectively elucidate the complete and local stereo-anatomy. METHODS: Computed tomography and magnetic resonance imaging scans were performed on 5 adult cadaver heads...

BACKGROUND: Rupture of a persistent trigeminal artery associated with development of a cavernous sinus fistula in a traumatic setting is rare. They are typically treated with coil embolization of the cavernous sinus. CASE DESCRIPTION: We present the case of a 42-year-old woman who developed a direct cavernous carotid fistula after a motor-vehicle accident. Angiographic imaging revealed a rupture point of a persistent trigeminal artery as it connected with the cavernous segment of the internal carotid artery (ICA), causing a cavernous sinus fistula...

BACKGROUND: When clinical presentation, laboratory studies, or imaging cannot diagnose cavernous sinus (CS) and/or Meckel's cave (MC) lesions, biopsy may be necessary. OBJECTIVE: To review our institutional series of biopsies of indeterminate CS and MC lesions. METHODS: Records from January 1994 to June 2016 were searched for biopsied indeterminate CS and MC lesions. We defined indeterminate as having an atypical imaging appearance or a broad differential and the need for tissue for definitive diagnosis...

An 86-year-old patient was hospitalized for fever and left acute orbital syndrome (red eye with moderate visual impairment, chemosis, ophthalmoplegia without proptosis, or any fundus involvement). CT scan showed superior ophthalmic vein and cavernous sinus enlargement complicating ipsilateral sphenoidal sinusitis. Magnetic resonance imaging (MRI) demonstrated the left cavernous sinus thrombosis extended to the ipsilateral jugular vein and transversal sinus (Lemierre syndrome). Intravenous broad-spectrum antibiotics and curative anticoagulation were prescribed...

INTRODUCTION: The etiology of Tolosa-Hunt Syndrome (THS) is still unknown. The initial standard magnetic resonance imaging (MRI) may not be sufficient for diagnosis, so dynamic contrast-enhanced MRI may be necessary to demonstrate the presence of lesions. METHODS: Seven patients diagnosed with THS according to the International Headache Society criteria (beta version) were included into the study. Patients were assessed in terms of type, age, symptoms and findings, accompanying disease, localization of the determined lesion, response to treatment, and clinical progress...

The authors report a rare case of bilateral Tolosa-Hunt syndrome, which occurred in a 80-year-old female and remitted spontaneously. Inflammatory lesions were found not only in typical locations, i.e. superior orbital fissures and cavernous sinuses, but also in the pituitary; these imitated gland's macroadenoma in imaging studies.
