We describe a rare case of chronic headache and hearing loss due to flow reversal in the left internal jugular vein and compensatory massive dilation of the right internal jugular vein. Flow reversal was caused by a prominent brachiocephalic trunk with subseqent compression of the vena brachiocephalica sinistra. Vascular anomalies and associated venous bypass circulation may be considered as a rare cause of non-specific malaise. Restoration of the physiological direction of blood flow should be discussed on an interdisciplinary basis given the unpredictable haemodynamic consequences.
