Summary
This case report details an asymptomatic substernal goiter found incidentally in a 78-year-old female. Surgery was deferred due to the absence of symptoms and malignancy, aligning with clinical guidelines.
Area of Science:
- Endocrinology
- Thoracic Surgery
Background:
- Substernal goiters, enlarged thyroid glands extending into the chest, can be asymptomatic or cause significant complications.
- Incidental findings of substernal masses require thorough investigation to determine etiology and management strategy.
Observation:
- A 78-year-old female presented with an incidental 3x5 cm calcified substernal mass identified via chest roentgenography.
- Computed tomography and aortography showed tracheal attachment, with unclear great vessel connections.
- Incisional biopsy confirmed benign thyroid tissue, leading to a diagnosis of substernal goiter.
Findings:
- The substernal mass was histopathologically confirmed as benign thyroid tissue, indicating a non-malignant substernal goiter.
- The patient was asymptomatic, and imaging suggested tracheal proximity without clear vascular compromise.
Implications:
- Conservative management is appropriate for asymptomatic substernal goiters without signs of malignancy or severe complications like respiratory distress or superior vena cava syndrome.
- This case underscores the importance of imaging and biopsy in differentiating benign from malignant substernal masses and guiding surgical indications.
