-Sx similar to hypercalcemic hyperparathyroidism= bone, renal, cardiac
-Distinguish from secondary hyperparathyroidism by measuring serum creatinne level (CKD) and vitamin D levels (vitamin D deficiency)

Question 2

Most likely locations of superior & inferior parathyroid gland

Answer 2

-Superior parathyroid gland: within 2-cm area of point of intersection of inferior thyroid artery & recurrent laryngeal nerve. However, if not found at anatomical location, tracheosophageal groove is most common location

-Thyrothymic ligament (cervical thymus, thymus, tongue of thymus) is the most common location of ectopic inferior parathyroid

-The most common location of a missed adenoma, if reoperating is the tracheoesophageal groove
