  Fig. 1 Imaging findings of the present case and the schematic representation of Dorello's canal. A: The patient presented with impaired abduction of the left eye. B: TOF-MRA image shows venous enhancement of the left IPS in the left Dorello's canal (arrowhead). C: True fast imaging with steady-state precession shows the abducens nerve (arrowhead). D: Angiogram from a left lateral view of the left vertebral artery reveals a dural arteriovenous fistula (arrows) in the left transverse-sigmoid sinus with retrograde drainage into the left IPS (arrowhead). E: Follow-up TOF-MRA image shows resolution of the venous enhancement of the left IPS (arrowhead). F: Schematic representation of the axial view of the skull base shows the anatomical location of Dorello's canal. G: The abducens nerve runs alongside the IPS in Dorello's canal before entering the cavernous sinus. IPS: inferior petrosal sinus, TOF-MRA: time-of-flight magnetic resonance angiography.
