    Ultrasound effectively locates enlarged parathyroid glands in hyperparathyroidism patients, improving surgical planning. This enhances diagnostic accuracy and reduces operative complications for better patient outcomes.

    Area of Science:

    • Endocrinology
    • Radiology
    • Surgical Oncology

    Background:

    • Hyperparathyroidism diagnosis often requires identifying enlarged parathyroid glands.
    • Surgical intervention is the primary treatment for hyperparathyroidism.
    • Accurate preoperative localization of parathyroid glands is crucial for successful surgery.

    Purpose of the Study:

    • To evaluate the efficacy of sonography in localizing enlarged parathyroid glands.
    • To determine the accuracy, sensitivity, and specificity of ultrasound for parathyroid localization.
    • To assess the impact of preoperative localization on surgical outcomes.

    Main Methods:

    • Sonographic localization using conventional and high-resolution real-time ultrasound (10 MHz) was performed.
    • The study included 37 patients with suspected hyperparathyroidism undergoing neck exploration.

  • Histopathological analysis confirmed parathyroid adenomas or hyperplasia in the surgical specimens.

    • Main Results:

    • Ultrasound demonstrated an overall accuracy of 84% for parathyroid localization.
    • The sensitivity was 79.5% and specificity was 98%.
    • Correct side and location prediction was achieved in 91% of cases, with false negatives attributed to ectopic glands and false positives to colloid cysts.

    Conclusions:

    • Preoperative sonographic localization of enlarged parathyroid glands facilitates surgical decision-making.
    • Improved localization reduces operative time and postoperative complications.
    • Ultrasound is a valuable tool for guiding parathyroid surgery, especially in complex cases.
