Summary
A rare intravagal parathyroid adenoma caused vagus nerve swelling and temporary vocal cord paralysis. Surgical removal resolved the palsy and normalized serum calcium levels.
Area of Science:
- Endocrinology
- Neurosurgery
- Pathology
Background:
- Parathyroid adenomas are typically found in the neck near the thyroid gland.
- Intravagal parathyroid adenomas, located within the vagus nerve sheath, are exceptionally rare.
Observation:
- A patient presented with a fusiform swelling of the left vagus nerve.
- The swelling was identified as an intravagal parathyroid adenoma.
Findings:
- Surgical excision of the intravagal parathyroid adenoma was performed.
- Post-operative recovery included resolution of left recurrent nerve palsy within two months.
- Serum calcium levels normalized by the tenth postoperative day without hypocalcemia symptoms.
Implications:
- This case highlights the importance of considering rare anatomical locations for parathyroid adenomas.
- Successful surgical management can lead to complete recovery from associated neurological deficits.
- Early diagnosis and intervention are crucial for managing symptomatic parathyroid tumors.
