“…Indeed, the presence of ectopic parathyroid tissue is a possible cause of failed neck explorations in the treatment of PHPT 6 8 10 13 17. Some patients may undergo surgery and parathyroidectomy only to have persistent hypercalcaemia, reinforcing the need for proper localisation before surgery to ensure success rates 12…”

This is a case of a 44-year-old woman with an anterior neck mass and hypothyroidism who presented with an incidental finding of an elevated serum calcium level and was found to have primary hyperparathyroidism and osteoporosis. During surgical exploration no parathyroid adenoma was found, although a nodule was palpated within the right thyroid lobe. Examination of the excised right thyroid lobe revealed an intrathyroidal parathyroid adenoma and chronic lymphocytic thyroiditis. After surgery, she did not develop severe hypocalcaemia and this was attributed to preoperative treatment with pamidronate. In the months following surgery, parathyroid hormone remained undetectable.

“…The reported prevalence of intrathyroidal parathyroid adenoma varied from 1.4-6%. [15,16] Embryologically, parathyroid glands originate from the third and fourth branchial pouches and migrate caudally to their final positions. It is conceivable that aberrations during migration result in anomalous locations and the parathyroid is trapped within the thyroid as the lateral lobe of the thyroid fuses with the isthmus.…”

Intrathyroidal parathyroid adenoma presenting with neuromuscular manifestation

Primary hyperparathyroidism (PHPT) is not an uncommon endocrine disorder. We describe a patient with PHPT who presented with progressive proximal limbs weakness and dystrophic changes of leg muscles. Serum calcium, alkaline phosphatase, and parathyroid hormone were elevated and serum phosphorus was low. Neck computerized tomography scan showed a parenchymatous tumor in the right lobe of the thyroid. The tumor presented as a 'cold nodule' in the dual-phase single-agent Tc-99m MIBI scan. The right lobectomy examination confirmed the diagnosis of an intrathyroidal parathyroid adenoma of the right gland.

We present a case of a 42-year-old woman with residual PHPT, operated elsewhere, with localisation of parathyroid tumour on ultrasonography and sestamibi scintigraphy on the right side of the thyroid gland (figure 1).…”

DESCRIPTIONIntrathyroidal parathyroid adenomas are an uncommon cause of primary hyperparathyroidism (PHPT) and their prevalence varies from 1.4% to 6%.1 2We present a case of a 42-year-old woman with residual PHPT, operated elsewhere, with localisation of parathyroid tumour on ultrasonography and sestamibi scintigraphy on the right side of the thyroid gland (figure 1). Review of the operative records revealed a search for the parathyroid tumour on the right side, along the eutopic sites of the superior and inferior parathyroids up to the innominate vein. Frozen section and histopathology revealed only normal parathyroids and the patient remained hypercalcaemic postoperatively.A few months later sestamibi scintigraphy was again performed with no change in the findings. Re-exploration did not reveal a tumour in the previously operated sites and hence the thyroid was carefully palpated and a nodule was felt in the right lobe of the thyroid. A hemithyroidectomy was performed and the cut section showed a parathyroid adenoma (1.7×0.9 cm) encircled by a rim of thyroid tissue confirming its intrathyroidal location (figure 2). Histopathology confirmed the same. Postoperatively the patient remained eucalcaemic.
