Dt. Kehagias et Aa. Kalovidouris, Graft-dependent recurrence of hyperparathyroidism: imaging with frequency amplitude and encoded Doppler sonography, EUR RADIOL, 10(9), 2000, pp. 1493-1494
A 48-year-old woman underwent total parathyroidectomy with autotransplantat
ion into the eft forearm due to secondary hyperparathyroidism. Recurrence o
f hyperparathyroidism was observed years later. B-mode high-resolution ultr
asonography of the left forearm demonstrated an ill-defined hypoechoic lesi
on. Frequency- and amplitude-encoded Doppler sonography revealed marked hyp
ervascularity,which was diagnostic for graft hyperplasia in association wit
h the history of the patient. These findings were confirmed by scintigraphy
and histological examination of the excised graft.
