Summary

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) syndrome is rare. This study presents two cases, highlighting unique symptoms and successful treatments with carbamazepine and corticosteroids.

Area of Science:

Neurology
Headache Medicine

Background:

SUNCT syndrome is a rare primary headache disorder characterized by severe unilateral orbital, supraorbital, or temporal pain.
It is associated with ipsilateral autonomic symptoms.

Observation:

Two patients with SUNCT syndrome presented with distinct clinical features.
Case 1: A 69-year-old man with supraorbital pain, lacrimation, conjunctival injection, triggered by head movements, and responsive to carbamazepine.
Case 2: A 48-year-old woman with severe attacks, burning sensation, marked autonomic signs including ptosis, and responsiveness to corticosteroids and carbamazepine.

Findings:

Both patients exhibited key features of SUNCT syndrome, including unilateral pain and autonomic symptoms.
Absence of rhinorrhea was noted in both cases.
Positive response to carbamazepine in both patients suggests a potential link to trigeminal neuralgia.

Implications:

These cases expand the understanding of SUNCT syndrome's clinical variability.
The positive response to carbamazepine supports its role in managing SUNCT and suggests a possible pathophysiological connection with trigeminal neuralgia.
Further research into treatment strategies for SUNCT syndrome is warranted.
