title: [Usefulness of power Doppler ultrasonography for the diagnosis of autoinfarction of parathyroid gland in secondary hyperparathyroidism].
abstract: Spontaneous remission due to parathyroid infarction of secondary hyperparathyroidism is rare compared with that of primary hyperparathyroidism, probably because several glands are enlarged in secondary hyperparathyroidism. Lately, neck ultrasound examination has become a more beneficial and specific method for the diagnosis of enlarged parathyroid glands in contrast to classic diagnostic techniques such as computed tomography (CT), magnetic resonance imaging (MRI) and scintigraphy. However, the diagnosis of parathyroid infarction reported in previous studies was often based on CT, MRI and scintigraphy findings and there are few studies that reported such diagnosis by urgent power Doppler ultrasonography of the neck. Here we present a hemodialysis patient with autoinfarction of the left parathyroid gland diagnosed by urgent power Doppler ultrasonography of the neck.
