Area of Science:

  • Neurology
  • Autonomic Nervous System Disorders

Background:

  • Harlequin syndrome is a rare autonomic disorder characterized by unilateral facial flushing and sweating, with contralateral impairment.
  • It is typically triggered by heat, emotion, or exercise.

Observation:

  • Two female patients, aged 32 and 39, presented with Harlequin syndrome.
  • One patient had no other neurological symptoms, and cervicothoracic spine MRI revealed no structural lesions.
  • The second patient, with a history of contralateral Horner's syndrome, showed a paravertebral thoracic tumor near the lung apex on MRI.

Findings:

  • The findings suggest a potential link between thoracic lesions and Harlequin syndrome, particularly in cases with associated neurological deficits.
  • The absence of lesions in one patient indicates that Harlequin syndrome can also occur idiopathically or due to other, yet unidentified, causes.

Implications:

  • Further research is needed to elucidate the precise pathophysiology of Harlequin syndrome.
  • Identifying underlying causes like thoracic tumors is crucial for timely diagnosis and management.
  • This case series contributes to understanding the spectrum of Harlequin syndrome presentations and diagnostic approaches.
