An overview of retrosternal goiter.

Area of Science:

• Endocrinology
• Thoracic Surgery

Background:

• Retrosternal goiters are thyroid enlargements extending into the chest.
• They can compress adjacent structures, leading to symptoms, primarily respiratory.
• Their incidence varies widely based on definition, affecting 0.2-45% of thyroidectomies.

Purpose of the Study:

• To review the characteristics, diagnosis, and management of retrosternal goiters.

Main Methods:

• Review of existing literature on retrosternal goiters.
• Discussion of diagnostic tools including thyroid function tests, chest radiography, and CT scans.
• Emphasis on surgical treatment and contraindications for fine-needle aspiration biopsy in substernal areas.

Main Results:

• Retrosternal goiters grow slowly and can reach the mediastinum.
• Compressive symptoms, especially respiratory manifestations, are common.
• Surgical intervention is the primary treatment modality.

Conclusions:

• Retrosternal goiters require surgical management due to limited efficacy of medical therapy.
• Diagnostic imaging is crucial for assessment.
• Biopsy in substernal regions should be approached with caution due to anatomical risks.
