Objective: It is not currently well known whether pheochromocytomas can be ruled out based on low intensity on T2-weighted sequences and signal loss on out-off phase magnetic resonance imaging (MRI) sequences. Hence, in this study we aimed to investigate whether biochemical screening for pheochromocytoma in patients with adrenal incidentalomas (AI) showing MRI features not suggesting pheochromocytoma would prove beneficial.Methods: We performed MRI for 3...

Objective: To compare the roles of inferior thyroid artery (ITA) peak systolic and end-diastolic velocities (PSV and EDV) measured by color flow Doppler ultrasonography (CFDUSG), TSH receptor antibody (TRAb) measured by M22 based ELISA and Tc-99m pertechnetate uptake for differential diagnosis between Graves’ disease (GD) and silent thyroiditis (ST).Methods: One hundred and fifty previously untreated subjects with GD (111 female, 39 male, mean age 3...

Introduction: The differential diagnosis between Graves’ disease (GD) and gestational transient thyrotoxicosis (GTT) is difficult in the absence of history and clinical features of GD. In this study, we aimed to determine the role of peak systolic (PSV) and end-diastolic velocities (EDV) of the right and left inferior thyroid arteries (ITA) as measured by color-flow Doppler ultrasonography (CFDUSG) for discriminating GTT from treatment naive GD.Meth...

Introduction: Atypical parathyroid tumour (APT) is a rare cause of primary hyperparathyroidism (PHPT) with a frequency of 1.2-1.3%. APT is a lesion with suspicious clinical and histological features of malignancy which does not completely respect the World Health Organization (WHO) criteria for diagnosis of Parathyroid Carcinoma (PC). There is a well-known association with PHT and medullary thyroid carcinoma for multiple endocrine neoplasia. However, concurrence of thyroid pap...
