Additional Information
Clinical Information
Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare type of headache classified under the ICD-10 code G44.059. This condition is characterized by specific clinical presentations, signs, symptoms, and patient characteristics that are essential for accurate diagnosis and management.
Clinical Presentation
Headache Characteristics
- Duration: SUNCT headaches are typically brief, lasting from a few seconds to about 10 minutes, but they can occur multiple times throughout the day.
- Location: The pain is unilateral, meaning it affects only one side of the head, often localized around the eye or temple.
- Quality of Pain: Patients often describe the pain as sharp, stabbing, or burning, which can be quite intense.
Associated Symptoms
- Conjunctival Injection: One of the hallmark features of SUNCT is redness of the conjunctiva (the membrane covering the eye), which occurs on the same side as the headache.
- Tearing: Patients may experience excessive tearing (lacrimation) on the affected side during headache episodes.
- Nasal Congestion: Some patients report nasal congestion or rhinorrhea (runny nose) on the same side as the headache.
- Ptosis: Drooping of the eyelid (ptosis) may also be observed during attacks.
Signs and Symptoms
Diagnostic Criteria
- Frequency: SUNCT is characterized by frequent attacks, which can occur several times a day, often in clusters.
- Triggers: Certain triggers may exacerbate the condition, including physical exertion, stress, or changes in temperature.
- Non-intractable: The specific designation of "not intractable" indicates that the headaches, while painful, do not persist continuously and can be managed with appropriate treatment.
Patient Characteristics
- Demographics: SUNCT typically affects adults, with a higher prevalence in males than females. The onset is often in middle age, although it can occur at any age.
- Comorbidities: Patients may have a history of other headache disorders, such as cluster headaches or migraines, which can complicate the clinical picture.
- Psychosocial Factors: Some studies suggest that psychological factors, such as anxiety or depression, may be more prevalent in patients with SUNCT, potentially influencing the perception of pain and headache frequency.
Conclusion
Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with SUNCT (ICD-10 code G44.059) is crucial for healthcare providers. This knowledge aids in the accurate diagnosis and effective management of this rare headache disorder. Given its unique features, including short duration, unilateral pain, and associated autonomic symptoms, SUNCT requires a tailored approach to treatment, often involving medications such as anticonvulsants or preventive therapies.

Diagnostic Criteria
The diagnosis of Short-lasting Unilateral Neuralgiform Headache with Conjunctival Injection and Tearing (SUNCT), classified under ICD-10 code G44.059, involves specific criteria that align with the International Classification of Headache Disorders (ICHD). Here’s a detailed overview of the diagnostic criteria and considerations for SUNCT:
Diagnostic Criteria for SUNCT
1. Headache Characteristics
- Unilateral Pain: The headache must occur on one side of the head.
- Short Duration: Each headache attack lasts from a few seconds to 10 minutes.
- Recurrent Episodes: Attacks occur in a series, with multiple episodes occurring within a day.
2. Associated Symptoms
- Conjunctival Injection: There is redness of the conjunctiva on the affected side.
- Tearing: Increased lacrimation (tearing) occurs on the same side as the headache.
- Nasal Congestion: Nasal stuffiness or rhinorrhea may also be present.
- Ptosis or Miosis: There may be drooping of the eyelid (ptosis) or constriction of the pupil (miosis) on the affected side.
3. Exclusion of Other Conditions
- The headache must not be attributable to another disorder, which means that other potential causes of the symptoms must be ruled out. This includes ensuring that the headache is not a result of secondary causes such as tumors, vascular disorders, or other neurological conditions.
4. Not Intractable
- The diagnosis specifically refers to SUNCT that is not intractable, meaning that the headache episodes are manageable and do not lead to significant disability or require aggressive treatment measures.
Clinical Considerations
1. Patient History
- A thorough patient history is essential to identify the pattern of headaches, associated symptoms, and any potential triggers. This includes documenting the frequency, duration, and intensity of the headaches.
2. Physical Examination
- A neurological examination may be performed to assess for any other neurological deficits or signs that could indicate a different underlying condition.
3. Diagnostic Imaging
- While not always necessary, imaging studies such as MRI or CT scans may be conducted to exclude secondary causes of headache, especially if the clinical presentation is atypical or if there are concerning features in the patient’s history.
4. Response to Treatment
- Observing the response to specific treatments can also aid in confirming the diagnosis. SUNCT may respond to certain medications, such as indomethacin or other analgesics, which can help differentiate it from other headache types.
Conclusion
The diagnosis of SUNCT (ICD-10 code G44.059) is based on a combination of specific headache characteristics, associated symptoms, and the exclusion of other potential causes. Clinicians must carefully evaluate the patient's history and symptoms to ensure an accurate diagnosis and appropriate management.

Treatment Guidelines
Short-lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is classified under the ICD-10 code G44.059. This condition is characterized by brief, severe headaches that are unilateral and often accompanied by autonomic symptoms such as conjunctival injection and tearing. While SUNCT is a rare form of headache, effective treatment options are available for managing its symptoms.
Overview of SUNCT
SUNCT is part of a group of headache disorders known as trigeminal autonomic cephalalgias (TACs). These headaches typically last from a few seconds to several minutes and can occur multiple times a day. The pain is often described as sharp or stabbing and is usually localized to one side of the head, often around the eye or temple area. The accompanying autonomic symptoms, such as redness of the eye and nasal congestion, can significantly impact the quality of life for those affected.
Standard Treatment Approaches
Acute Treatment
-
Triptans: Medications such as sumatriptan can be effective for acute attacks. They work by stimulating serotonin receptors, which can help alleviate headache pain. However, their efficacy may vary among individuals with SUNCT.
-
Local Anesthetics: In some cases, local anesthetics like lidocaine can be administered intranasally or via injection to provide rapid relief during an attack.
-
Opioids: While not typically first-line treatments due to the risk of dependence, opioids may be considered for patients who do not respond to other therapies.
Preventive Treatment
-
Anticonvulsants: Medications such as lamotrigine and topiramate have shown promise in reducing the frequency of SUNCT attacks. These drugs help stabilize neuronal activity and can be effective in preventing headache episodes.
-
Calcium Channel Blockers: Verapamil, a calcium channel blocker, is sometimes used as a preventive treatment. It may help reduce the frequency and severity of attacks.
-
Corticosteroids: In cases where SUNCT is persistent, corticosteroids may be prescribed to reduce inflammation and provide relief.
-
Deep Brain Stimulation (DBS): For patients with intractable SUNCT, deep brain stimulation has been explored as a treatment option. This involves implanting a device that sends electrical impulses to specific brain regions, potentially reducing headache frequency and severity[4].
Lifestyle and Supportive Measures
- Avoiding Triggers: Identifying and avoiding potential headache triggers, such as certain foods, stress, or sleep disturbances, can be beneficial.
- Cognitive Behavioral Therapy (CBT): Engaging in CBT or other forms of psychological support may help patients cope with the emotional impact of chronic headache disorders.
Conclusion
Managing SUNCT effectively requires a tailored approach that considers the individual patient's response to various treatments. While acute treatments can provide immediate relief, preventive strategies are crucial for long-term management. Collaboration with a healthcare provider specializing in headache disorders is essential for optimizing treatment outcomes and improving the quality of life for those affected by SUNCT.
