Objective: To describe an unusual presentation of a patient with recurrent pituitary apoplexy of an adenoma that switched phenotypes from a nonfunctioning, or silent gonadotroph adenoma (SGA), to a silent corticotroph adenoma (SCA). We
At the age of 18, our patient was diagnosed as complete androgen insensitivity syndrome(AIS) based on androgen receptor studies in cultured genital skin fibroblasts. Compatible with this diagnosis, both testosterone and LH levels in her plasma were elevated as compared to levels in normal females.
The syndrome of pituitary apoplexy has been reported to occur after the administration of several different medications. We report a case in which pituitary apoplexy developed shortly after the administration of leuprolide in a patient with prostate cancer. Leuprolide is a potent gonadotrophin
Gonadotrophin-releasing hormone agonists (GnRHAs) are used in many clinical conditions, particularly prostate cancer. There have been a few case reports of apoplexy from a previously undiagnosed pituitary tumour, occurring within hours to days of initiation of GnRHA therapy. We report a case of
Summary: Gonadotropin-releasing hormone (GnRH) agonists, currently used in the treatment of advanced prostate cancer, have been described as a rare cause of pituitary apoplexy, a potentially life-threatening clinical condition. We report
Pituitary apoplexy represents an uncommon endocrine emergency with potentially life-threatening consequences. Drug-induced pituitary apoplexy is a rare but important consideration when evaluating patients with this presentation. We describe an unusual case of a patient with a known pituitary
Pituitary apoplexy is a rare endocrine emergency. The extent to which hyperglycaemia is a contributory risk factor in the precipitation of pituitary apoplexy is not known. A 38-year-old man with poorly controlled diabetes presented to the emergency department with sudden onset of nausea and headache
The objective of this article is to review clinical outcomes in patients presenting with pituitary apoplexy and compare the results of conservative and surgical management. It took the form of a retrospective review of 30 patients (23M, 7F; age range: 17-86 years) with pituitary apoplexy diagnosed
Thirty-seven patients with pituitary apoplexy were analyzed with an emphasis on clinical presentation and visual outcome. Their mean age was 56.6 years, with a male to female ratio of 2:1. Presenting symptoms included headache (95%), vomiting (69%), ocular paresis (78%), and reduction in visual
OBJECTIVE
The term classical pituitary apoplexy describes a clinical syndrome characterized by sudden headache, vomiting, visual impairment and meningismus caused by the rapid enlargement of a pituitary adenoma usually due to haemorrhagic infarction of the tumour. Most published reports looking at
Treatment of prostatic cancer with GnRH agonist is a medical alternative to surgical castration, although hyperstimulation of the tumor can occur. We describe an unusual unwanted effect of such a treatment which unmasked a clinically silent gonadotroph adenoma. A 62-year-old man developed after the
Secreting pituitary adenomas have marked prevalence in pediatric adenomas. We described a case of an 11-year-old boy with pituitary null cell macroadenoma with silent macroscopic pituitary apoplexy. The patient was admitted with bitemporal hemianopsia and a gradual deterioration of visual acuity. An
Ten consecutive patients with subarachnoid hemorrhage (SAH) of unknown cause were examined for sellar abnormalities and pituitary dysfunction. The diagnosis of SAH rested on a typical history and the demonstration of blood in the cerebrospinal fluid (computed tomography (CT), lumbar puncture).
: Hypopituitarism includes all clinical conditions that result in partial or complete failure of the anterior and posterior lobe of the pituitary gland's ability to secrete hormones. The aim of management is usually to replace the target-hormone of hypothalamo-pituitary-endocrine gland axis
