Clinical Report: International Consensus on the Evaluation and Management of Hypothalamic Hamartomas

Background

Hypothalamic hamartomas are rare brain lesions often linked to refractory epilepsy and various comorbidities. This consensus study aims to establish best-practice recommendations for the diagnosis and management of HH.

Data Highlights

The consensus study evaluated 257 questions across two rounds, achieving consensus on 82% of questions, indicating a strong agreement among experts on key aspects of HH management.

Key Findings

• Key diagnostic features include gelastic and dacrystic seizures.
• A 3T epilepsy-protocol MRI is essential for diagnosis.
• Baseline neuropsychological and endocrinologic assessments are recommended.
• Surgical evaluation should be initiated after the first antiseizure medication failure.
• MR-guided laser interstitial thermal therapy is preferred for Delalande II–III lesions.
• Postoperative MRI is recommended at 6–12 months.

Clinical Implications

The consensus emphasizes the importance of a multidisciplinary approach in managing HH.

Conclusion

This consensus provides a standardized framework for the evaluation and management of hypothalamic hamartomas.
