A 38-year-old man was admitted for possible embolization of a left carotid cavernous sinus fistula. Two months previously, the patient had been admitted to the hospital after a motorcycle accident. Twenty-four hours later, he was noted to have left proptosis, chemosis, and a third-nerve palsy. An angiogram was performed and showed a carotid cavernous sinus fistula (Fig. 1 A). The patient was re...

This paper reports a case of spontaneous indirect carotid cavernous fistula that presented with pulsatile tinnitus, left-sided temporal headache and left-sided ptosis. The pulsatile tinnitus, its aetiology and investigation are discussed. The importance of pulsatile tinnitus is highlighted, with a discussion of carotid-cavernous fistulas. This case illustrates that clinically silent cavernous s...

A 44-year-old man developed bilateral blindness following severe periorbital cellulitis and pansinusitis. CT and MR imaging demonstrated bilateral cavernous sinus thrombosis. Diffusion-weighted imaging revealed reduced apparent diffusion coefficient in bilateral optic nerves, suggesting optic nerve ischemia caused by the cavernous sinus thrombophlebitis (CST). Following surgical debridement of ...

Abstract Background Isolated sphenoid sinus disease (ISSD) is a rare, often misdiagnosed condition of the paranasal sinus. If left untreated, it can lead to complications involving pituitary gland, cavernous sinus, neurologic, and vascular structures nearby. Case report We present case 60-year-old female with history severe left-sided headache, facial pain, diplopia, lateral rectus palsy. She w...

AIM The purpose of this study was to describe two challenging cases of septic cavernous sinus thrombosis (CST), which presented with vastly different clinical signs and symptoms. METHODS We present two cases of CST with markedly differing clinical presentations, medical comorbidities, and degree of impairment. Initial imaging of each patient failed to show thromboembolic disease. RESULTS Bo...
