Area of Science:

  • Neurology
  • Headache Medicine

Background:

  • Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) is a rare primary headache disorder.
  • Characterized by frequent, short-lasting attacks of severe unilateral head pain accompanied by autonomic symptoms.

Observation:

  • The study reports four cases of a severe manifestation termed "SUNCT status."
  • This status involved an extreme aggregation of typical SUNCT attacks, occurring for 1-3 consecutive days.
  • Investigator-witnessed attacks confirmed the severity and duration of the episodes.

Findings:

  • No intracranial lesions were identified in any of the four patients through supplementary examinations.
  • A follow-up period exceeding five years supports the conclusion that these cases are not symptomatic of an underlying intracranial lesion.

  • The findings suggest that "SUNCT status" may represent a rare, albeit distinct, clinical feature of the SUNCT syndrome.

    • Implications:

    • This observation expands the known clinical spectrum of SUNCT.
    • It highlights the possibility of severe, prolonged "SUNCT status" episodes in patients with primary SUNCT.
    • Further research may be warranted to understand the pathophysiology and optimal management of this rare presentation.
