Presentation This is the scan of the neck in a 65-year-old woman with complaints of audible bruits in the left ear and papilledema. She has a past history of left Sylvian fissure meningioma.

Caption: Spectral waveforms of both common carotid arteries

Description: The right CCA exhibits normal spectral waveform. The left CCA has a turbulent flow and exhibits high flow velocities [in the range of 180 cm/sec]

Caption: Spectral waveforms of both external carotid arteries

Description: The right ECA demonstrates a normal arterial waveform and flow velocity. The left ECA demonstrates a turbulent flow and elevated flow velocities.

Caption: Spectral waveforms of both internal carotid arteries

Description: Both the internal carotid arteries demonstrate normal spectral waveforms with normal flow velocities.

Caption: Spectral waveforms of both vertebral arteries

Description: Both the vertebral arteries exhibit normal flow velocities. The left vertebral artery however demonstrates a turbulent flow.

Caption: Spectral waveforms of both subclavian arteries

Description: Both the subclavian arteries exhibit a normal spectral waveform with normal flow velocities.

Differential Diagnosis Elevated velocities of the left CCA, left ECA suggest an indirect evidence of a left dural arterio-venous malformation

Final Diagnosis Left dural arterio-venous malformation

Follow Up An angiogram and MRI was performed which showed a left dural arterio-venous malformation.
