Introduction: Pituitary apoplexy is a rare acute complication in patients with functioning pituitary adenomas (including acromegaly) often followed by hypopituitarism and occasionally may show remission of symptoms after an apoplectic episode. We report this in an acromegalic patient who developed remission following pituitary apoplexy.Case report: A 24 years old woman is diagnosed with acromegaly after presenting for a period of 6 months moderate headac...

Introduction: Isolated acquired ACTH deficiency is rare; it may be due to hypophysitis and association with other autoimmune diseases was reported.Case report: E.L, female, aged 34, was diagnosed with primary autoimmune hypothyroidism and premature ovarian failure; levothyroxine and estroprogestins were administered. Suddenly, the patient developed vomiting, shivers without fever and soon coma installed, with tonic-clonic seizures. There was no history o...

Introduction: Exogenous Cushing’s syndrome is a challenging diagnosis in non-compliant patients or in cases with difficult anamnesis, while the access to self medication is relatively open.Aim: We present a young female case presenting with tertiary adrenal insufficiency.Case report: S.C., 40 years old has progressively weight gain of 30 kilos since the last year. The Body Mass Index is 40 kg/m2, with androgen redis...

Introduction: Pituitary incidentaloma is a relatively frequent imagistic finding. Since no therapy is necessary, the follow up protocol is the most important in patients’ approach.Aim: We present a study in patients diagnosed with pituitary incidentaloma, admitted in I.Parhon, Bucharest, between 1999 and 2011.Patients and method: This is a retrospective study in 140 patients, diagnosed with pituitary incidentaloma based on CT ...

Introduction: The concentrations of pituitary hormones in the cerebrospinal fluid (CSF) are much lower that their serum counterpart.Aim: To study the CSF access for pituitary glycoprotein hormones (GPH) in patients with pituitary adenomas (PA).Patients and methods: In 221 cases submitted to transsphenoidal surgery for PA (85 acromegaly – ACM, 92 nonfunctioning pituitary adenomas – NFA, 44 prolactinomas – PRM) the sur...

Introduction: Parasellar extension of macroprolactinomas defined on imaging criteria was reported to be an independent predictor of hormonal resistance to dopamine agonists (DA).Methods: Two hundred and twelve patients with macroprolactinomas (87 M/125 F), treated with DA for 5 years median period; prolactin (fluoroimmunoassay or chemiluminescence), CT scan and/or MRI with contrast agents were performed; maximum diameter evolution was reported.<p cla...

Pituitary apoplexy is a rare syndrome due to hemorrhagic infarction of a pituitary adenoma. We analyze the circumstances of diagnosis, clinical features and evolution in a retrospective review of patients with pituitary apoplexy admitted between 2000 and 2010, diagnosed by pathological exam and/or suggestive imaging for pituitary haemorrhage.Results: From 31 patients with pituitary apoplexy (11 women, 20 men) with a mean age of 48 years at diagnosis (20&...

Introduction: Turner syndrome is a common cause of dwarfism and hypogonadism as is pituitary failure. However the association of the two is rarely thought and reported in the literature. We present two cases of women with hypogonadism diagnosed with Turner syndrome with various degrees of pituitary insuficiency.Case report: The first case presented at 16 years with secondary amenorrhea and showed slightly disharmonic dwarfism. A hypogonadotropic hypogona...

It has been generally believed that clinically functioning pituitary adenomas are highly specialized neoplastic lesions, which produce a unique hormone. Increasing body of evidence argue against this concept, since about half of prolactinomas (PRM) and approximately 60% of TSH-secreting adenomas are multihormonal and 30–40% of GH-secreting adenomas co-secrete PRL. Most of classically considered null cell adenomas have been proved to be immunohistochemical positive for gon...

At least one fifth of pituitary adenomas exhibit plurihormonality when using immunohistochemistry for anterior pituitary hormones. However, the correlation with clinical features is weak, without an agreement upon pathological predictors of tumour behaviour.The aim was to determine the immunoreactivity for anterior pituitary hormones and alpha subunit in 276 consecutive pituitary adenoma patients, aged 22–79 years (44.3±8), 154 F/ 122 M: 83 acr...
