Introduction: Horner’s syndrome represents a clinical symptom that may result from a variety of lesions both in the central and peripheral nervous system. It is a combination of ipsilateral ptosis, pupillary miosis and anisocoria, enophthalmos and facial anhydrosis induced by disruption of the sympathetic innervation of the eye anywhere along its three-neuron trail. Tumors are the most frequent causes of Horner’s syndrome.Aim: Aim of the study ...

Introduction: Increased production of vasopressin plays a key role in the development of fluid retention and hyponatremia in patients with decompensated heart failure. Antidiuretic hormone deficiency in the course of diabetes insipidus leads to the loss of water, dehydration and hypernatremia. The aim of the study was to present difficulties in successful treatment of hyponatremia in a patient with cardiomyopathy and heart failure, receiving desmopressin because of postoperati...

Introduction: Bilateral adrenalectomy (BA) is rarely applied as a therapeutic procedure. It serves as a life-saving treatment in patients with persistent Cushing’s disease after an ineffective pituitary surgery or in ectopic ACTH production. Other indications for BA are: bilateral adrenocortical adenomas, congenital adrenal hyperplasia and bilateral phaeochromocytoma in patients with hereditary paraganglioma-phaeochromocytoma (PPS/PGL) syndromes. It is also a procedure of...

Introduction: Hyponatremia occurs in 33–69% of women with postpartum pituitary necrosis. The aim of the study was to present a patient in whom recurrent hyponatremia was one of the dominant symptoms of postpartum anterior pituitary hormones deficiency.A case report: 55-year-old woman with a diagnosis of Sheehan syndrome established 19 years after the last labor complicated by massive bleeding due to uterine atonia. The first symptoms of pituitary in...

Introduction: Neoplastic lesions in the retroperitoneum may originate from kidneys, ureters, adrenal glands or peripheral nervous, connective, muscle and adipose tissues. Neuroendocrine tumours are exceptionally located in the retroperitoneum.The case study: A woman aged 51, with a tumour of the left adrenal gland found incidentally during an ultrasound examination of the abdominal cavity, which was performed because of dysuria. A CT confir...

Introduction: Acromegaly with normal IGF-1level is rarely diagnosed and is difficult to recognize. In acromegalic pa-tients with poorly controlled diabetes, malnutrition, hepatic injury, hepatic congestion due to heart fail-ure, inflammatory diseases, renal dysfunction, and malignant neoplasm, IGF-1 synthesis is inhibited and thus in such cases normal IGF-1 levels may be observed. The aim of the study is to present a rare case of a patient with acromegaly and normal IGF-1 leve...

Background: Copeptin (pre-proAVP) secreted in equimolar amounts with vasopressin (AVP) closely reflects AVP release. Previously it was shown that copeptin is stimulated in standard pituitary function tests acting through hypothalamic centres. Furthermore, copeptin has been shown to subtly mirror stress potentially mediated via CRH. To further test a potential direct interaction of CRH with copeptin release which could augment AVP effects on pituitary function, we investigated ...

Introduction: Atypical pituitary adenomas are often characterized by rapid growth and massive invasion of the surrounding structures. Usually, they are associated with poor prognosis and high recurrence rate due to resistance to conventional therapies. When surgery and radiation are ineffective, alternative therapies remain the last line treatment. Lately, a novel chemotherapy with capecitabine and temozolomide was proposed as a highly effective and extending the life of the p...

Introduction: Adrenal medullary hyperplasia (AMH) is a rare syndrome of catecholamine excess. Adrenal overgrowth is usually bilateral. Due to similar clinical signs, laboratory results and radiological adrenal picture, AMH can be misdiagnosed as pheochromocytoma. The only method that allows determining a proper diagnosis of AMH is pathologic examination. It is regarded as a precursor of pheochromocytoma and has been reported as a component of MEN2.Aim: T...

Introduction: Immunoglobulin-G4-related disease (IgG4RD) is a multidisciplinary problem due to plasmatic cells infiltration and areas of fibrosis in the affected tissues. In IgG4RD, elevation of serum IgG4 immunoglobulins is present. Clinically, the disease is mainly manifested as: autoimmune pancreatitis, salivary gland involvement, sclerosing cholangitis, lymphadenopathy, lachrymal gland enlargement, retroperitoneal fibrosis or orbital pseudotumor. The simultaneous involveme...
