Introduction: Thyrotropin-producing adenomas (TSH-omas) constitute about 1% of pituitary adenomas. TSH-omas are a rare cause of hyperthyroidism. In conjunction with biochemical parameters and dynamic endocrine testing, image evaluation of the pituitary gland and sella turcica is mandatory for establishing a correct diagnosis. TSH-omas are usually large tumors and tend to be invasive. Greater amounts of invasion correlate with incomplete surgical removal of the tumor and, thus,...

Introduction: Central diabetes insipidus is a disorder characterized by polyuria and polydipsia due to vasopressin deficiency caused by a lesion at the hypothalamo-hypophyseal axis. Frequently, central diabetes insipidus is wrongly considered idiopathic if not associated with other neurological signs and symptoms. Herein we present the report of a case that illustrates the difficulties in the diagnosis of this condition.Case report: A 17 year-old male wa...

Introduction/ objectives: Turner syndrome (TS) comprises a group of sex chromosomal abnormalities of heterogeneous clinical presentation. During the infant period, the pediatric endocrinologist coordinates their follow-up and it is important to ensure its continuation during the adult stage. The objective of this study is to know the current clinical situation, occupational, educational, social and medical monitoring of patients affected TS in Tenerife.M...

Introduction: Classic congenital adrenal hyperplasia due to 21-hydroxylase deficiency (classic 21-OHD CAH) is the most common form of congenital adrenal hyperplasia, characterized by simple virilizing or salt wasting forms. The saline loss picture develops after birth and it can evolve in a short time to a severe picture of hypotonic dehydration and hypovolemic shock with lethal consequences if not diagnosed and treated. Herein we present an unusual case of classic 21-OHD CAH ...

Introduction: Hypophysary aneurysms are rare, they account for 1% to 2% of all intracranial aneurysms (1) and can be mistaken for pituitary adenomas, since they can have similar symptoms and even radiological signs especially if it’s an aneurysm completely thrombosed as angiography will show only avascular mass (2).Clinical case: A 84 year old female with past medical history of hypertension, dyslipidemia and depressive disorder, presents to emergen...

Introduction: Esthesioneuroblastoma is an uncommon malignant neoplasm with an average 5-year survival rate of about 45%. Ectopic ACTH syndrome due to esthesioneuroblastoma is extremely rare and there have been very few cases reported.Case report: A 54-year-old woman was admitted to our hospital with symptoms of leg edema and general fatigue of one month’s duration. Physical examination showed moon facies and edema on her lower extremities bilaterall...

Introduction: Hyperthyroidism has been described as a rare cause of pulmonary hypertension (PH) as well as systemic arteriovenous fistulas. However, we describe a case of pulmonary hypertension secondary to an intrathyroid arteriovenous fistula, not previously described in the literature.Case report: A 56 year old woman followed in our consultations with multinodular goiter and a long standing hyperthyroidism, secondary to Graves Basedow disease with dif...

Background: Acromegaly is usually caused by a benign pituitary tumour, with increased production of growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Treatment options include surgery, followed by pharmacological treatment with dopamine agonists, somatostatin analogues, GH receptor antagonists or radiotherapy. Treatment optimization is important to decrease the burden of this often-chronic disease on the patient.Objectives: To evaluate the ef...

Background: T2-weighted magnetic resonance imaging (MRI) signal has been recently linked with a better tumor response to pasireotide treatment in patients with acromegaly (ACRO). Our aim was to evaluate the prevalence of this radiological feature and its association to therapeutic outcomes in a large cohort of ACRO patients treated with pasireotide.Methods: A retrospective multicentre study was performed in 15 Spanish tertiary university hospitals includ...
