Summary
Intrathyroidal parathyroid adenomas, though rare, are a significant cause of failed hyperparathyroidism surgery. Early identification and ipsilateral thyroid lobectomy can effectively treat these cases.
Area of Science:
- Endocrinology
- Surgical Pathology
- Head and Neck Surgery
Background:
- Parathyroidectomy for hyperparathyroidism relies on identifying all parathyroid glands.
- The incidence of intrathyroidal parathyroid adenomas is historically considered low.
- Subtotal thyroidectomy's role in identifying these glands is debated.
Purpose of the Study:
- To evaluate the incidence and management of intrathyroidal parathyroid adenomas.
- To determine if intrathyroidal adenomas are an under-recognized cause of surgical failure.
Main Methods:
- Retrospective review of 97 cervical explorations for hyperparathyroidism (1978-1992).
- Analysis of patient demographics, surgical findings, and outcomes.
- Identification and treatment of intrathyroidal parathyroid adenomas.
Main Results:
- Four patients (4%) presented with intrathyroidal parathyroid adenomas.
- Adenomas were located superiorly or inferiorly within the thyroid lobe.
- Ipsilateral partial or subtotal thyroid lobectomy achieved cure in all affected patients.
- One adenoma extensively involved the thyroid lobe.
Conclusions:
- Intrathyroidal parathyroid adenomas occur more frequently than previously reported.
- This condition is a potential cause of persistent or recurrent hyperparathyroidism after initial surgery.
- Ipsilateral thyroid lobectomy is a curative treatment for intrathyroidal parathyroid adenomas.
