A case of intracranial hemorrhage due to rupture of aneurysm of the distal posterior cerebral artery associated with dural arteriovenous fistulas of the falcine sinus

Abstract

Objective: This report describes a rare case of a dural arteriovenous fistula of the falcine sinus associated with a flow-related aneurysm.

Patient and Methods: A 68-year-old man presented with severe headache secondary to an intracranial hemorrhage. The bleeding was caused by a dural arteriovenous fistula (dAVF) of the falcine sinus with a flow-related aneurysm of the dural branch of the right posterior cerebral artery.

Results: Trans arterial obliteration of the aneurysm and its feeder using glue and trans venous embolization of the draining portions using a coil were successfully performed.

Conclusion: The unusual coexistence of a flow-related aneurysm on the feeder of the dAVF resulted in a unique hemorrhage.
