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 outp...

A 36 years of old patient was admitted to the intensive care unit of cardiology when he experienced palpitations and orthopnea. The patient’s complaints started about 2 years ago as syncope and sudden shortness of breath. Thorax CT showed pleural effusion and increased cardiothoracic index. Findings on ECHO were : Ejection fraction 35%, severe mitral regurgitation and global hypokinesia. Coronary angiogram showed a fibrocalcific plaque noted in in the distal LAD. The pati...

Aim: It is hypotethically thought that increased frequency of breast cancer in patients with primary hyperparathyroidism(PHPT)may be due to the fact that calcium accumulation in the breast may be higher in patients with PHPT giving rise to more breast-related examinations. Although there are many studies or case reports showing calcification in many organs and tissues, in PHPT, there is not any study investigating breast calcification in these patients in the literature. We ai...

Background: Hypoparathyroidism (HypoPT) is a rare condition that is characterized by hypocalcemia and hyperphosphatemia due to low or inappropriately normal serum levels of parathyroid hormone (PTH) for at least 6 months. The long-term complications of hypoparathyroidism indicate the necessity of screening them. In the follow-up of these patients according to hypoparathyroidism guidelines is recommended; calcium, phosphorus, albumin, magnesium, creatinine, and eGFR levels shou...

Introduction: Insulinoma is a rare neuroendocrine tumor that is difficult to diagnose due to its obscure location. Conventional radiographic methods have low sensitivity and are inadequate to detect insulinoma. Selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma that could not be located by radiographic methods and evaluated them with SACST.Case 1: A 48-...

Introduction: While Graves’ disease is a common cause of thyrotoxicosis, tyroid hormone resistance (THR) is a rare cause of high thyroid hormones. Coexistence of Graves’ disease and THR which can cause quite a lot of difficulties in diagnosis and treatment was reported very rarely in the literature. Here, we report a patient with THR and Graves’ disease in whom remission was achieved with medical therapy.Case: A 38-year-old woman applied t...

Aim: To determine whether early repeat fine needle aspiration biopsy(FNAB) has an effect on adequate or atypia of undetermined significance/follicular lesion of undetermined significance(AUS/FLUS) cytology rates in thyroid nodules with inadequate or AUS/FLUS in the first FNAB.Method: Nodules of patients who underwent repeat biopsy due to insufficient or AUS/FLUS cytology between 2019-2022 were included. Demographic data of the patients and ultrasonograph...

Introduction: Immune checkpoint inhibitors are relatively new and promising treatments for a variety of solid tumors. Nivolumab is an anti-cancer monoclonal antibody that inhibits anti-programmed death-1 (PD1) and modulates T-cell response. It has been shown to significantly improve survival in many types of cancer, but clinical studies have also reported an increased risk of developing immune-related adverse events. In particular, immune-related adverse events may be related ...

Von Hippel-Lindau (VHL) syndrome is a pathological condition that causes various clinical symptoms and is difficult to diagnose. The most common pathological lesions are hemangioblastomas of the central nervous system, retinal angiomas, renal clear cell carcinomas, and pheochromocytomas. Here we reposrt a case of likely to be VHL due to his family history.Case: A 33-year-old male suffering from hypertension and a history of hemangioblastoma operated in 2...

Background: Primary Hyperparathyroidism (PHPT) is a common endocrine disorder that is characterized by hypercalcaemia and elevated or inappropriately normal serum levels of parathyroid hormone. Most often, the presentation of PHPT is asymptomatic. PHPT can manifest with osteoporosis and hypercalciuria as well as with vertebral fractures and nephrolithiasis, both of which can be asymptomatic. Our aim in this study; to determine the frequency of kidney stones in patients operate...
