BACKGROUND: Acute vision loss in the post-partum period can occur due to many reasons. Eclampsia, posterior reversible encephalopathy syndrome (PRES), pituitary apoplexy, and central serous retinopathy are some of the important causes. Cryptococcal meningitis as a cause of acute vision loss in the post-partum period has not been mentioned in literature. CASE PRESENTATION: A 25-year-old female presented to us with acute bilateral complete vision loss in the post-partum period...

Pituitary adenomas usually arise from the anterior lobe of the pituitary gland and are manifested with hormonal disorders or mass effect. Mass effect usually occurs in nonfunctional tumors. Pituitary adenomas may be manifested with visual field defects or rarely in the form of total oculomotor palsy. Visual field defect is most frequently in the form of bitemporal hemianopsia and superior temporal defect. Sudden loss of vision, papilledema and ophthalmoplegia may be observed. Pituitary apoplexy is defined as an acute clinical syndrome characterized with headache, vomiting, loss of vision, ophthalmoplegia and clouding of consciousness...

BACKGROUND Pituitary macroadenoma is a common benign tumor that usually presents with visual field defects or hormonal abnormalities. Cerebral infarction can be a complication of a large pituitary adenoma. We report a rare case of bilateral anterior cerebral arteries infarcts by a large pituitary macroadenoma with apoplexy. CASE REPORT A 48-year-old male patient presented with altered conscious level and sudden loss of vision for one-day duration. Magnetic resonance imaging of the brain showed a large seller and suprasellar hemorrhagic mass of pituitary origin, with associated bilateral areas of diffusion restriction in the frontal parasagittal regions, consistent with infarctions...

OBJECTIVE: To describe 2 cases of macroprolactinomas with atypical presentation in women desiring pregnancy that illustrate important considerations in the management approach for macroprolactinomas in reproductive-aged women. PATIENTS: Case 1 was a 26-year-old woman referred to our institution for possible tumor resection after pituitary apoplexy during her first pregnancy. Instead, she underwent treatment with cabergoline for a year with goals of normalization of prolactin and decrease in tumor size to <1 cm before trying to conceive...

INTRODUCTION: Pituitary tumor apoplexy can result from either hemorrhagic or infarctive expansion of pituitary adenomas, and related mass effect can result in compression of critical neurovascular structures. The time course of recovery of visual field deficits, headaches, ophthalmoparesis, and pituitary dysfunction after endoscopic transsphenoidal surgery has not been well established. METHODS: Medical records were retrospectively reviewed for all patients who underwent endoscopic transsphenoidal surgery for pituitary tumor apoplexy from April 2008 to November 2014...

Pituitary apoplexy is a medical condition that needs urgent diagnosis and treatment. It may occur spontaneously or may be precipitated by a variety of reasons including dynamic endocrine tests. Although pituitary apoplexy is usually seen in non-functional pituitary adenoma, it can also be seen in ACTH secreting macroadenomas. ACTH secreting adenomas present usually as microadenomas and in these patients apoplexy is rarely seen. In this paper we present a 30 years old male patient with a history of Cushing's disease who suffered from pituitary apoplexy after1 mg dexamethasone suppression test...

BACKGROUND: Pituitary apoplexy is a rare complication of the initial administration of leuprolide acetate. CASE DESCRIPTION: The authors present the case of a 63-year-old man who experienced headache, blurred vision, and loss of consciousness following initial leuprolide treatment for prostate carcinoma. Neuroimaging demonstrated pituitary hemorrhage. CONCLUSION: Clinicians should be aware of this rare but known complication of leuprolide injection so that prompt diagnosis and treatment initiation occur in patients with leuprolide-associated pituitary apoplexy...

Clinically nonfunctioning pituitary adenomas (NFPA) are the most common pituitary tumors after prolactinomas. The absence of clinical symptoms of hormonal hypersecretion can contribute to the late diagnosis of the disease. Thus, the majority of patients seek medical attention for signs and symptoms resulting from mass effect, such as neuro-ophthalmologic symptoms and hypopituitarism. Other presentations include pituitary apoplexy or an incidental finding on imaging studies. Mass effect and hypopituitarism impose high morbidity and mortality...

Pituitary tuberculoma is extremely rare, even in endemic regions of tuberculosis and much less frequently as a presentation of pituitary apoplexy. We describe a 25-year-old female presented with sudden onset of headache and vision loss of left eye which mimicking symptoms of pituitary apoplexy. MRI of the pituitary gland showed a rim-enhancing lesion at the intrasellar region extending into the suprasellar area, but absence of posterior bright spot with enhancement of the pituitary stalk. Pituitary hormonal evaluation revealed panhypopituitarism and diabetes insipidus...

BACKGROUND: Severe headache during pregnancy is a challenging condition that may rarely imply endocrine disturbances. Rapid recognition of pituitary apoplexy is needed to improve pregnancy outcome. OBJECTIVE: To review and compare maternal and fetal outcomes after pituitary apoplexy. METHODS: Four cases of pituitary apoplexy during pregnancy in our centre are reported and literature review covering the past 54 years was performed. RESULTS: In the four cases presented and the 33 reported in the literature, most women presented with severe headaches and systemic symptoms...

BACKGROUND: It is rare for patients with pituitary apoplexy to exhibit concomitant subarachnoid hemorrhage (SAH). Only a handful of patients with pituitary apoplexy have developed such hemorrhagic complications, and histopathological examination revealed pituitary adenoma as the cause of SAH. CASE REPORT: A previously healthy 35-year-old woman was brought to our institution after complaining of severe headache and left monocular blindness. Brain computed tomography showed a diffuse SAH with a central low density...

An 83-year-old woman was admitted to our hospital with a severe headache and purpura. She had previously been diagnosed with idiopathic thrombocytopenia purpura (ITP) and achieved complete remission with steroid therapy. Steroid therapy had been completed one week prior to the current admission. The recurrence of severe thrombocytopenia (<1.0×10(4) platelets/μl) was detected and a CT scan revealed pituitary hemorrhage without pituitary adenoma. She received steroid therapy combined with intravenous immunoglobulin, which resulted in the amelioration of ITP and improvements in the pituitary hemorrhage...

BACKGROUND: Several retrospective investigations have recommended more passive surgical indications for intratumoral hemorrhage of pituitary adenomas due to probable spontaneous resolution. However, no definitive analyses have compared pituitary adenomas with hemorrhagic apoplexy and intratumoral hemorrhage without evident apoplectic symptoms or pituitary adenoma infarction. METHODS: This study retrospectively identified 43 patients with symptomatic pituitary apoplexy among 1067 patients with pituitary adenomas initially treated by surgery at a single institute between April 2005 and May 2015, with 27 cases of hemorrhagic (2...

Neurologists should be aware of specific urgent and emergent neuro-ophthalmic conditions, including giant cell arteritis, arterial dissection, intracranial aneurysm, pituitary apoplexy, and invasive sino-orbital fungal infection (eg, mucormycosis). Early recognition and treatment can greatly impact patient morbidity and mortality, including the preservation of vision and life. Neurologists should be cognizant of the key and differentiating clinical and radiographic features for these presentations.

BACKGROUND: Pituitary apoplexy (PA) often presents with acute headache and neuro-ophthalmic manifestations, including ocular motility dysfunction (OMD) from cranial nerve palsies (CNPs). Our goal was to describe the epidemiology and outcomes of OMD in a large, single-center series of patients with PA. METHODS: We conducted a retrospective chart review of all patients with PA seen in our pituitary center between January 1995 and December 2012. Presenting neuro-ophthalmic, endocrine, and radiologic data, as well as neuro-ophthalmology follow-up data, were collected...

The pituitary gland plays a critical role in reproduction. In response to the hypothalamus the anterior pituitary secretes prolactin, thyroid stimulating hormone (TSH), Adreno corticotropic hormone (ACTH), follicle stimulating hormone (FSH), luteinizing hormone (LH) and growth hormone. Dysregulation in these hormones often lead to reproductive failure. Multiple mechanisms of pituitary injury exist. Simmond's disease is atrophy or destruction of the anterior lobe of the pituitary gland resulting in hypopitiutaryism...

We report the case of a 70-year-old man presenting with pituitary apoplexy from a macroprolactinoma and ventriculitis. It was not possible to distinguish a bacterial or chemical origin, on the basis of his clinical presentation, laboratory studies and imaging, highlighting the importance of prompt imaging and attainment of CSF cultures, in making the diagnosis.
