Introduction:
We present a case of direct carotico-cavernous fistula (CCF) and its successful treatment.
Presentation Of Case:
A 55-year-old male presented with left eye discomfort, diplopia and pulsatile tinnitus. He had a recent history of head injury. Examination showed proptosis, chemosis, orbital bruit, and abducens nerve palsy. Digital subtraction angiography confirmed CCF, which was managed endovascularly. The patient recovered fully after treatment.
Discussion:
CCF has a variety of presenting clinical signs, imaging manifestations, and treatment options available.
Conclusion:
CCF is a rare and dangerous neurological disorder that should be promptly diagnosed and treated.
