Twenty-eight patients (19 men, 9 women; mean age, 56 years) with clinical and laboratory evidence of hyperparathyroidism underwent preoperative color Doppler ultrasonography and ultrasound-guided FNAC prior to surgery. On ultrasonography, the parathyroid lesions were anechoic or hypoechoic, located behind or at the margin of the thyroid gland, and mimicked blood vessels in some cases. On color Doppler ultrasound, parathyroid lesions showed little or no vascularity. They were easily differentiated from blood vessels, thus improving the safety of ultrasound- guided FNAC. Thirty-four (76%) of 45 surgically confirmed parathyroid lesions were detected with ultrasonography in 21 (75%) of the patients. There was no significant difference in the detection rates of lesions in the right upper, right lower, left upper, and left lower parathyroid glands. Eight (29%) patients had coexisting thyroid lesions. FNAC of the ultrasound-detected abnormalities provided preoperative confirmation that they were parathyroid lesions. In conclusion, our findings show that color Doppler ultrasonography in combination with ultrasound-guided FNAC is useful for preoperative localization of parathyroid lesions. |
