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...

Aim: Familial hypercholesterolemia (FH) is an autosomal dominant genetic disease characterized by increased levels of low density lipoprotein cholesterol (LDL-chol). Despite relatively high prevalance and significant association with increased mortality, the awareness of physicians and patients is low and it is an underdiagnosed and undertreated disease. We aimed to detect patients with FH and determine treatment status and compliance.Materials and metho...

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...

Aim: Although nonsecretory parathyroid carcinoma is relatively more frequent, nonsecretory parathyroid adenoma was also reported. It is thought to precede functioning parathyroid adenoma.Case report: An iso-hypoechoic 6.5×9.5×16.1 mm thyroid nodule with irregular borders in the superior-posterior part of right thyroid lobe was observed in ultrasonography in a 44-year-old female euthyroid patient. Fine-needle aspiration (FNAB) biopsy resulted wi...

Introduction: Parathyroid surgical therapy differs because the glands are small and of variable number and location. Although localization studies have improved greatly, we may not reliably determine the number and location of all diseased glands preoperatively. Ultrasonography (US) is the most widely used imaging method. In this study, we aimed to demonstrate how the surgical outcomes change when the surgeon accompanies the endocrinologist during preoperative ultrasonography ...

Introduction: Parathyroid carcinoma (PC) is a rare endocrine malignancy which accounts for 0.005% of all cancers and less than 1% of primary hyperparathyroidism cases. This uncommon tumor usually occurs during the fifth decade of life, with equal frequency in both sexes, and has an indolent but progressive course. It’s frequently symptomatic and patients may have high values of serum calcium and parathyroid hormone (PTH) with a palpable cervical mass. PC generally occurs ...

Introduction: Musculoskeletal system is widely affected in acromegalic patients which might cause difficulties in the diagnosis and treatment of inflammatory rheumatological diseases. Here, we report coexistent rheumatoid arthritis (RA) in three acromegalic patients presenting with continuing joint and back pain although acromegalic state was in remission.Case 1: A 64 years old female patient with acromegaly and macroadenoma had undergone transsphenoidal...

Introduction: Prolactinomas are the most common hormonally active pituitary tumors that account for 40–60% of all pituitary adenomas and are usually successfully treated with dopamine agonists. Surgery or radiotherapy is reserved for drug intolerance/resistance or in neuro-ophthalmological emergencies. We present a patient with refractory microprolactinoma with empty sella treated by transsphenoidal surgery.Case: 42-year-old female patient admitted ...

Introduction: Thyroid carcinoma is common in young women. Radioactive iodine (RAI) therapy has been confirmed as a useful treatment in the management of differentiated thyroid carcinoma (DTC). For women with DTC, the effect of RAI therapy on gonadal and reproductive function is an important consideration. We aimed to evaluate effects of RAI therapy on ovarian function.Method: Women younger than 40 years old and diagnosed with thyroid cancer that required...

Introduction: Hysterosalphingography (HSG) is the radiographic examination of uterine cavity and fallopian tubes. It is generally used during evaluation of infertility and radioopaque contrast is injected through cervical duct during the procedure. Lipiodol which is the most commonly used contrast media in HSG is a fatsoluble iodinated contrast media. This iodine is progressively cleared from the body in a period ranging from a few weeks to a few months. Here, we present a 6 w...
