Introduction: Thyrotropin secreting pituitary adenomas are rare constituting <2% of pituitary adenomas. Thirty percent of these tumors may be plurihormonal. Most common cosecreted hormone is GH and the least one is PRL. We report here a case of plurihormonal pituitary adenoma symptomatic for TSH secretion.Case report: A 35-year-old female admitted to hospital because of fatigue, heat intolerance, headache, galactorrhea and menstrual irregularity. Her...

Thyroidectomy is the definitive treatment for toxic multinodular goiter (TXMNG). Surgery should be performed when the patient is euthyroid which decreases perioperative cardiac risks. Plasmapheresis is a procedure that removes the thyroid hormones from the circulation. It is an alternative method in case of resistance or contraindications to anti thyroid drugs. Role of plasmapheresis in the treatment of TXMNG is not fully determined in the literature. We report a case with TXM...

Introduction: Sertoli–Leydig cell tumours are rare tumours which account for <1% of all solid ovarian tumors. It mostly occurs in 2–4° decades of life. Rapidly progessing symptoms/signs of androgen excess suggest the presence of and androgen secreting tumor.Case: Two postmenopausal patients (50 and 57 year-old) were referred to our Endocrinology Clinic for evaluation of worsening hirsutism. Both of patients had manifestations of hypera...

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...

Background: Currently, there is no satisfying treatment option other than gross total or subtotal resection in combination with adjuvant radiotherapy for the treatment of craniopharyngiomas. However, recurrence could occur in a substantial proportion of craniopharyngiomas despite gross total resection and radiotherapy. Human epidermal growth factor receptor 2 (HER-2/ErbB2) overexpression was determined in various human carcinomas and is associated with aggressive clinical beha...

Introduction: The treatment of choice in Cushing’s disease (CD) is transsphenoidal adenomectomy. However, the long term recurrence rate of the CD after transsphenoidal surgery in Turkish patients has not been determined so far.Purpose: We aimed to determine the long term recurrence rates of CD in Turkish patients after transsphenoidal surgery.Methods: The computer records of the 23 patients, operated for CD in our center durin...

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...

Background: With the increasing use of USG, MRI and CT, adrenal lesions are frequently found in the daily practice. These lesions may be primary or secondary in origin. However, it is important to resolve whether these lesions are benign or malignant.Purpose: The aim of this case detection study was to compare FDG-PET CT with MRI in differentiating benign from malignant adrenal mass lesions.Patients: All patients were admitted to o...

Background: MEN-1 is a rare disease characterized by parathyroid adenoma or hyperplasia, pituitary adenoma and pancreatic neuroendocrine tumors (PNET). Gastrinomas are the most common functional PNET in MEN-1 disease. Insulinomas and glucagonomas constitute approximately 20 and 3% of PNET’s in MEN-1 disease. Most of insulinomas are benign in nature but about 70% of cases of glucagonomas present with metastasis at diagnosis. Coexistence of various PNET’s are very rare...

Background: Obesity and diabetes mellitus (DM) are the features of Cushing’s disease (CD). Studies indicated different frequencies of CD among obese, type 2 DM patients. The frequency of CD among obese, type 2 DM have’nt been studied in Turkey. Therefore, we aimed to assess the frequency of CD among obese (BMI>30 kg/m2) type 2 DM patients that had not classical morphological findings of CD.Patients and methods: Two hundred consec...
