Introduction: With the advent of modern imaging, up to 30% of adrenal pheochromocytomas are discovered incidentally in asymptomatic patients. Smaller tumors may be ‘pre-biochemical’ in their secretory capacity, but truly nonfunctioning tumors over 3 cm are exceedingly rare. We describe a case of a clinically and biochemically silent pheochromocytoma.Case report: A 65-year-old woman was found to have a left adrenal incidentaloma on an abdominal ...

Introduction: Acromegaly is a chronic disorder usually caused by growth hormone (GH)-secreting pituitary adenomas. Transsphenoidal surgery remains a treatment of choice for restoring GH to normal levels. The aim of this study was to illustrate the relationship between some factors and transsphenoidal surgery outcomes.Patients and methods: We retrospectively analysed the outcome of 31 patients with acromegaly after initial endoscopic transsphenoidal surge...

Aim: Dopamine agonist (DA) therapy is recommended as first-line treatment for prolactinomas, albeit with long treatment duration and high recurrence rate after treatment withdrawal. The aim of this retrospective study was to evaluate predictors for successful DA withdrawal.Methods: The study included 59 prolactinoma patients (39 female, 20 male; age 34 (18–82) years) that were treated with DA (35.6% on cabergoline); the duration of treatment was 71 ...

Introduction: Hashimoto’s thyroiditis is known to induce nodularity in the thyroid and in some cases to coexist with papillary thyroid carcinoma. However, the effect of the development of Hashimoto’s thyroiditis on the course of nodular goiter is not known.Aim: The aim was to describe the effect of the development of Hashimoto’s thyroiditis in the course of nodular goiter.Methods: A cohort of 12 patients, female, age...

Pheochromocytoma is a rare disease but frequently poses a diagnostic dilemma due to the unspecific symptoms and its potentially life-threatening nature. There is a perception of an increase in the incidence of pheocromocytomas in recent years, but no data on time trends exist. We obtained data from The Danish National Registry of Patients, The Danish Registry of Causes of Death, and The National Pathology Registry for all persons registered with pheochromocytoma in 1977–2...

Prepubertally gonadectomized (GDX) wild-type DBA/2J mice develop adrenocortical neoplasms presenting with small spindle-shaped non steroidogenic A-cells and large lipid-laden, steroidogenic and mitotically active B-cells. Neoplastic B-cells overexpress estrogen receptor α (ERα, Ers1) and β (ERβ, Ers2), aromatase (CYP19a1) and produce sex-steroids, resembling gonadal rest tissue. To test the role of estrogen-ER system in adrenocortical tumor progression, GDX...

Aim: The etiology and underlying pathology of non-functional adrenal adenoma has not been clearly defined, yet. Blood pressure levels according to adrenal adenoma size has not been evaluated, yet. Therefore, we evaluated 24 hour ambulatory blood pressure levels in patients with non functional adrenal adenoma.Materials & Methods: We studied thirty newly diagnosed adrenal adenoma patients in a tertiary health-care center. They grouped in two categories...

Introduction: Previous studies demonstrated a relationship between T1- and T2-weighted signal intensity and tumor growth pattern in pituitary somatotropinomas. The goal of this retrospective study was to analyze the MRI characteristics of pituitary macroadenomas with different hormonal activity in newly diagnosed patients.Material and methods: Pre-treatment T1- and T2-weighted MR-images (Intera Achieva, PHILIPS, 3.0T) of patients with 42 non-functional a...

Background: Pituitary adenomas (PA) are common intracranial tumors that are mainly considered benign. A small group of patients exhibit clinically aggressive behavior sometimes unrelated to the histopathological or radiological features.Methods: Twelve patients were selected harboring a PA with clinical features of aggressiveness. All the patients underwent pre and postoperative endocrinologic/neuroradiologic evaluation.Results: 10...

Background/objectives: Hypothalamic obesity (HO) occurs in 50% of patients with the pituitary tumor Craniopharyngioma (CP). Attempts have been made to predict the risk of HO based on hypothalamic (HT) damage on magnetic resonance imaging (MRI), but none have included volumetry. Qualitative and quantitative (volumetric) analyses of HT damage was performed. The results were explored in relation to feeding related peptides and body fat.Subjects/methods: A c...
