    High-resolution ultrasound effectively locates enlarged parathyroid glands in patients with suspected primary hyperparathyroidism. This imaging technique offers high accuracy, especially in reoperation cases, guiding surgical planning for improved outcomes.

    Area of Science:

    • Endocrinology
    • Medical Imaging
    • Surgery

    Background:

    • Primary hyperparathyroidism often involves enlarged parathyroid glands, necessitating accurate preoperative localization for successful surgical intervention.
    • Diagnostic imaging plays a crucial role in identifying the location and size of abnormal parathyroid glands prior to surgery.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of high-resolution real-time sonography for preoperative localization of enlarged parathyroid glands in patients with suspected primary hyperparathyroidism.
    • To assess the sensitivity and specificity of sonography in identifying parathyroid adenomas, particularly in cases requiring reoperation.

    Main Methods:

    • A prospective study involving 165 consecutive patients with suspected primary hyperparathyroidism.
    • Preoperative high-resolution real-time sonography was performed to localize enlarged parathyroid glands.

  • Analysis of sonographic findings in relation to adenoma size, serum calcium, and parathyroid hormone levels.

    • Main Results:

    • Overall sensitivity and specificity for localizing enlarged parathyroid glands were 69% and 94%, respectively.
    • In patients undergoing neck reoperation (n=21), sensitivity increased to 80% and specificity remained high at 92%.
    • A correlation was observed between sonographic accuracy, adenoma size, and biochemical markers (serum calcium and PTH).

    Conclusions:

    • High-resolution sonography is a valuable and accurate tool for the preoperative localization of enlarged parathyroid glands.
    • The procedure is particularly effective in reoperation scenarios, improving diagnostic yield.
    • Sonography aids in surgical planning for primary hyperparathyroidism by providing precise localization of affected glands.
