Carotid-Cavernous sinus fistula (CCF) represents a misdiagnosed condition with potential repercussion in functional, neurological, and social roles of patients with this disease. Earlier reports remark on the efficiency and safety of endovascular therapy with resolution of the symptoms were performed appropriately. We present a case of a male patient from a developing country, with gunshot wound head trauma history and short-term progressive functional and neurological impairment in the presence of intracranial hypertension and ocular symptoms who developed a large CFF, subsequently treated by transradial access embolization. We aim to describe the real-world experience in diagnosis and treatment of CCFs, emphasizing on the scope and outcomes of the endovascular treatment. This case supports worldwide experience, positioning endovascular therapy as an effective strategy in the resolution of CFFs, and the relevance of suspecting this disease in the presence of typical symptoms, even if they are rapidly progressive.
