| PURPOSE :To evaluate the accuracy and ultrasonographic findings of primary and secondary hyperparathyroidism
(HPT) and correlate them with pathologic results.
MATERIALS and METHODS : We reviewed 31 cases of surgically confirmed primary (n=22) and secondary (n=9) hy-perparathyroidism.
We used 10 or 7.5 MHz linear transducer and reviewed the location, contour, size and e-chogenicity
of lesions. Then we evaluated the detection rate of parathyroid lesions based on surgical result and
compared the result of 99mTc-sestamibi scan (15 cases).
RESULTS : Location of primary HPT was left lower in 9, left upper in 5, right lower in 4, right upper in 3, left mid
portion in 1 and superior mediastinum in 1. Lesions showed variable echogenicity -- mild low echo (2), moder-ate
low echo (10), severe low echo (2), isoecho (4) and heterogeneous echo pattern (1). All the lesions except 5
were well defined and 3 lesions had echogenic rim. Posterior enhancement and lateral shadowing were noted in
3 and 4 lesions, respectively. Nineteen of 23 primary lesions were detected by ultrasonography (82.6%) and well
correlated with sestamibi scan. In cases of secondary HPT, most were well defined low echoic nodular lesions,
and we could detect 6 of 9 patients (67%) and 15 of 36 lesions (41.7%). Only 6 of 24 secondary lesions were de-tected
by sestamibi scan (25%).
CONCLUSION : The detection rate of ultrasonography in primary HPT was fairly good and well correlated with the
result of the
9 9 m
Tc-sestamibi scan, but both diagnostic modalities were not promising in secondary HPT. |
