Abstract
Aim This case report highlights the importance of preoperative assessment of calcium in all cases of thyroid surgery. Intrathyroidal parathyroid adenoma (IPA) is a rare presentation of primary hyperparathyroidism. It is caused by abnormal embryonic migration of parathyroid glands and is difficult to detect preoperatively. When diagnosed pre operatively it has good surgical outcome. Herein authors present a case of thirty-two-year lady who underwent hemithyroidectomy for colloid goitre and was detected to have intrathyroidal parathyroid adenoma (IPA) on histopathological examination.
