A 72-year-old woman had been diagnosed with hyperparathyroidism five years before coming to the Norman Parathyroid Center. Despite elevated calcium and parathyroid hormone levels, her condition was attributed to vitamin D deficiency, and treatment focused on supplements rather than addressing the underlying disease.
Over those five years, she continued to experience classic symptoms of hyperparathyroidism including fatigue, bone pain, and brain fog. Her kidney function and bone density also worsened over time.
On the day of surgery, imaging appeared to show a left lower parathyroid adenoma. However, during surgery, the true overactive gland was found in a different location, an enlarged left upper parathyroid adenoma. Even more unusual, she was found to have five parathyroid glands instead of the typical four.
This case demonstrates several important lessons. Elevated calcium with “normal” or elevated PTH should not be dismissed as vitamin D deficiency alone. Imaging can also be misleading, and focusing only on the gland seen on a scan can leave patients uncured. A complete evaluation of all parathyroid glands allowed the true source of the disease to be identified and treated successfully.
Parathyroid disease can present in many different ways, which is why experience and a comprehensive surgical approach matter. Become our patient here: https://www.parathyroid.com/patient
