Three Extremely Rare Findings in the Same Patient: Harlequin Syndrome, Thyrocervical Trunk Aneurysm, and Systemic-Pulmonary Arterio-Arterial Fistula

Harlequin syndrome is a rare autonomic disorder characterized by unilateral diminished sweating and flushing of the face in response to heat or exercise. Extrinsic ganglion compressions, most of the times by neoplasms, can induce the syndrome. During investigation of a 27-year-old woman presenting Harlequin syndrome with diminished sweating on the left side and flushing of the right half of her face, a left thyrocervical trunk aneurysm was detected by angio-magnetic resonance imaging. Thyrocervical trunk aneurysms are rare, and only a few cases have been reported.
