THE cavernous sinus is a vascular channel of great importance not only in ophthalmology but in many other branches of medicine. Descriptions of its structure are scattered in books and journals on ophthalmology, otorhinolaryngology, paediatrics, and dentistry as well as in the standard anatomical works. However, the descriptions of the sinus and its contents show great variation and it is the p...

Seven patients with vascular disease (four with cavernous and two with transverse sinus dural fistulas and one with a facial arteriovenous malformation, all supplied primarily from cavernous branches of the internal carotid artery) underwent subselective catheterization and embolization. Ten branches were catheterized (seven meningohypophyseal trunks and three inferolateral trunks) and eight br...

Thrombosis of superior ophthalmic veins (SOV) is a well known entity occurring secondary to varied etiologies. We describe diffusion restriction in thrombosed SOV in two cases of different etiologies- bilateral involvement in a patient with septic cavernous sinus thrombosis (CST) and another where embolisation of an indirect carotico-cavernous fistula (CCF) resulted in complete SOV thrombosis a...

directly related with intracerebral hemorrhage in dural arteriovenous fistula (DAVF) because the cortical vein anatomically exists in the subarachnoid space [1]. Hemorrhage is the most serious event in cranial DAVF. Cortical venous reflux (CVR) has been known as a prognostic risk factor for hemorrhage in cranial DAVF [2]. Hemorrhage risk is related to lesion location, sex and cortical venous re...

The clinical manifestations of dural arteriovenous fistulas (dAVFs) are highly variable and dependent on the hemodynamic properties location fistula. locations fistula numerous include cavernous sinus, transverse–sigmoid superior sagittal inferior petrosal sinuses, anterior condylar confluence, tentorium, cranial fossa, middle foramen magnum, cranio-cervical junction, convexity, spinal cord. Th...

A trombose do seio cavernoso (TSC) é uma situação clínica rara, resultando normalmente da complicação de um processo infeccioso dos seios paranasais. Outras causas incluem alterações pró-trombóticas, anemia e trauma. Os sinais e sintomas são extremamente variados e inespecíficos, sendo o seu diagnóstico efetuado através de ressonância magnética nuclear (RMN). Os autores apresentam um caso clíni...

Cavernous angiomas (cavernomas) of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1- and hyperintense in T2-weighted images. Differential diagnosis with para-sellar meningiomas and schwannomas can be difficult. We report three cases of this condition, desc...

Investigators from the Children's Hospital of Philadelphia analyzed the clinical and radiographic findings in 12 cases of cavernous sinus thrombosis (CST) seen between 2000 and 2013, and conducted a literature search and review of the pooled data.

Septic cavernous sinus thrombosis is a rare clinical condition. Although Staphylococcus aureus is the most common pathogen causing septic cavernous sinus thrombosis [CST], it is an uncommon cause of meningitis. We report the first case of CST with meningitis in Hyderabad, Andhra Pradesh, caused by community acquired epidemic strain of Methicillin resistant staphylococcus aureus [MRSA], in a pre...
