Introduction: The aldosterone-to-renin ratio (A/R) is the most frequently used screening test for primary hyperaldosteronism (PH) and a confirmation test is recommended when it is high. We aimed to determine the frequency of PH in patients with high A/R and investigated possible clinical features that might help to prevent unnecesary confirmation tests.Method: Patients who underwent saline infusion test because of high A/R (>3.8) were retrospectively...

Objective: Currently there are three well-established treatment options for hyperthyroid Graves’ disease (GD): antithyroid drug therapy with thionamides, radioactive iodine (RAI) treatment with (131)I, and surgery. The aim of this study was to investigate retrospectively theurapeutic options of the patients with GD treated at outpatient clinics of Endocrinology and Metabolism between January 2007 and December 2009.Methods: We evaluated 122 patients ...

Aim: To determine whether multiple fine needle passes to the same thyroid nodule in the fine needle aspiration biopsy (FNA) session affect sufficient and/or atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) cytological result.Materials and Methods: Ultrasonography (US) and cyto-histopathology results of the nodules of patients who were diagnosed with thyroid nodules and underwent FNA between May-August 2021 wer...

Backgorund: Adrenal incidentalomas (AI) are lesions discovered incidentally on imaging without clinical symptoms or examination findings. AI can produce hormones in 5-30% of cases. Autonomic cortisol secretion (ACS) is the most common of these. Although ACS is asymptomatic, it increases the risk of metabolic disorders.Methods: Patients aged ≥18 years with adrenal adenoma and upper abdominal MRI who presented and were examined in the endocrinology o...

Introduction: 80–90% of insulinomas are smaller than 2 cm, equally located in the head, body and tail of pancreas. Computer tomography (CT) is 75%, magnetic resonance imaging (MRI) is 55–90%, endoscopic ultrasonography (EUS) is 85–95% and selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma which could not be located by conventional methods and evaluated with SAC...

Introduction: Ectopic adrenocorticotropic hormone (ACTH) syndrome is characterized by hypercortisolism due to the hypersecretion of non-pituitary ACTH-secreting tumor leads to the Cushing’s syndrome. Herein, we present a case with Cushing’s syndrome, which is diagnosed ACTH-secreting renal malignant paraganglioma.Case: A 40-year-old woman presented with a 5 month history of newly diagnosed hypertension and diabetes, weakness, hyperpigmentation,...

Introduction: Rathke’s cleft cyst is one of the pituitary non-adenomatous tumors that found in about 20% of pituitary glands at autopsy. Symptomatic Rathke’s cleft cysts are rarely, but these cysts can cause serious medical problems associated with compression of the pituitary gland, pituitary stalk, optic nerve or hypothalamus. Here, we report a rare case of 73 years old man with sudden onset headache due to Rathke’s cleft cyst present with symptoms and radiolo...

Introduction: Klinefelter syndrome is known as the set of symptoms that result from two or more X chromosomes in males. There is no known association of this syndrome with GH hypersecretion. The most remarkable symptom is gigantism and it can also be observed in androgen deficient states as such as the Klinefelter syndrome and some more genetic syndromes such as the Sotos syndrome, the Marfan syndrome, the homocystinuria, and the fragile X-syndrome. Herein we presente...

Introduction: Parathyroid lipoadenoma (PLA) is a rarely seen, benign variant of parathyroid adenoma (PA). However, PA usually consists of uniform, polygonal chief cells with a few nests of oxyphil cells, PLA consists of similar histologic features, but with an abundance of fat cells. Additionally, PLA may be functional with the secretion of parathyroid hormone (PTH) or non-functional. Here, we present a case of atypical PLA presented with severe hypercalcemia and skeletal defo...

Introduction: Tolosa Hunt syndrome (THS) is described as unilateral orbital pain associated with paresis of one or more of the third, fourth and/or sixth cranial nerves caused by a granulomatous inflammation in the cavernous sinus, superior orbital fissure or orbit. Pituitary gland is rarely involved in this syndrome. Herein we represented a case with hypophysitis with Tolosa Hunt who was operated with the suspicion of pituitary adenoma.Case: A 63-year-o...
