Summary
This case study highlights a patient with lingual thyroid who experienced throat lump and dysphagia. Thyroxine therapy normalized thyroid-stimulating hormone (TSH) levels and resolved symptoms, demonstrating its importance in managing lingual thyroid.
Area of Science:
- Endocrinology
- Head and Neck Surgery
Background:
- Lingual thyroid is a rare congenital condition where thyroid tissue is located in the tongue.
- Patients may remain asymptomatic for years before developing complications.
Observation:
- A patient with a documented lingual thyroid presented with a new throat lump and dysphagia after 15 asymptomatic years.
- Initial thyroid function tests were normal, but serum TSH levels were elevated.
- Symptoms included difficulty swallowing and a noticeable lump in the throat.
Findings:
- Thyroid-stimulating hormone (TSH) levels were twice the normal range.
- Treatment with thyroxine led to the normalization of TSH levels.
- The patient's symptoms of dysphagia and throat lump were completely relieved.
Implications:
- TSH determination is crucial for monitoring lingual thyroid patients.
- Suppressive thyroid hormone therapy, such as thyroxine, is effective in managing symptomatic lingual thyroid.
- Early diagnosis and management can prevent severe symptoms and improve patient outcomes.
