Genetic characterization of large parathyroid adenomas

In this study, we genetically characterized parathyroid adenomas with large glandular weights, for which independent observations suggest pronounced clinical manifestations. Large parathyroid adenomas (LPTAs) were defined as the 5% largest sporadic parathyroid adenomas identified among the 590 cases operated in our institution during 2005-2009. The LPTA group showed a higher relative number of ...

Dynamic 4D MRI for Characterization of Parathyroid Adenomas: Multiparametric Analysis.

BACKGROUND AND PURPOSE The hypervascular nature of parathyroid adenomas can be explored by proper dynamic imaging to narrow the target lesions for surgical exploration. The purpose of this study was to establish MR perfusion characteristics of parathyroid adenomas to differentiate them from their mimics, such as subjacent thyroid tissue and cervical lymph nodes. MATERIALS AND METHODS Preopera...

Multiple ectopic parathyroid adenomas.

CONTEXT Primary hyperparathyroidism is the most common cause of hypercalcemia in unselected patients. The ectopic gland locations should be known for appropriate surgical exploration and for avoiding subsequent re-exploration that would represent higher morbidity. Multiple ectopic glands are rare and present a particular challenge in parathyroid surgery. CASE REPORT A 65-year-old female prese...

Nuclear diameter in parathyroid adenomas.

Nuclear diameter was measured in 55 parathyroid chief-cell adenomas to determine its value in histological diagnosis and to assess its relationship to other features of primary hyperparathyroidism. Mean nuclear diameter for the whole group of adenomas was significantly greater than that for the accompanying normal glands. Mean nuclear diameter in individual adenomas was significantly greater th...

Parathyroid adenomas and cardiovascular risk.

In recent decades, primary hyperparathyroidism (pHPT) has changed its clinical presentation from a disease with bone and renal involvement to a frequently asymptomatic disorder detected on routine biochemistry. Nevertheless, it remains unclear whether patients with untreated mild asymptomatic hyperparathyroidism are at risk for other complications such as increased morbidity and mortality from ...
