ABSTRACT
Objective: To describe a rare case of trigeminal neuralgia (TN)
secondary a dural tentorial arteriovenous fistula (DAVF).
Case report: We describe a case of a 70 year-old male with
diagnosis of TN, an MRI showed a hypointense signal lesion with a
hyperintense core in the left perimesencephalic cistern suggesting
the occurrence of a vascular structure. The diagnosis of TN due to
vascular malformation was established. Then a cerebral angiography
showed a Dural Arteriovenous Fistula dependent of the left carotid
system. He was treated by endovascular therapy. The following day
after the procedure was completed the patient showed marked
improvement of his symptoms, without presenting pain recurrence
and he was hospital discharged 4 days after admission. The patient
remains asymptomatic 6 months after the procedure.
Conclusions: TN secondary to DAVF is an extremely rare condition.
Our patient represents the 15 reported case in the world literature.
Although several therapeutic approaches have been described,
endovascular therapy is more constantly employed in these cases. In
the patient described here endovascular treatment produced pain
remission with no recurrence. Though, in TN cases due to DAVF the
optimum treatment remains unclear.
