Pituitary apoplexy

Pituitary apoplexy refers to a rare clinical syndrome consisting of signs and symptoms that occur due to rapid expansion of the contents of the sella turcica . It can occur spontaneously or associated with pituitary tumors. It can have a broad clinical spectrum, but usually presents with severe headache, visual impairment and hypopituitarism. Sudden onset of symptoms associated to imagiologic confirmation makes the diagnosis. Surgical treatment is advised when there is important compression of the optic tract...

Pituitary apoplexy is an endocrine-related emergency most commonly caused by hemorrhage into a preexisting pituitary adenoma. Known risk factors for such hemorrhage include major surgical procedures, head trauma, pregnancy, anticoagulation, and the administration of hormone therapies for the correction of primary hypothalamic deficiencies. Elective orthopedic surgery is an uncommon precipitator of pituitary apoplexy that is rarely described. We report the case of a patient with a previously unknown pituitary macroadenoma who developed apoplexy as a complication of elective right total hip arthroplasty...

A man in his late 40s with no significant medical history presented with 2 weeks of lethargy, nausea and dizziness, alongside worsening headaches. Initial assessment revealed severe hyponatraemia and secondary hypothyroidism; urgent MRI pituitary was requested with a clinical suspicion of pituitary apoplexy. This demonstrated a likely cystic pituitary adenoma, with further testing revealing pituitary gland suppression, leading to a diagnosis of chronic secondary hypopituitarism. Initiating hormone replacement allowed substantial reported improvements in this patient's quality of life...

BACKGROUND: Combined surgery consisting of endoscopic trans-sphenoidal surgery (ETSS) and transcranial (TC) surgery for giant pituitary adenomas (GPAs) has been recommended to prevent lethal postoperative apoplexy. Based on our experience, we attempt to rationalize the indications for such surgery. MATERIALS AND METHODS: We report the magnetic resonance (MR) characteristics of the tumor and the outcomes in patients with GPAs who underwent ETSS only and combined surgery...

BACKGROUND AND AIMS: Pituitary apoplexy (PA) is a rare neurosurgical emergency, associated with deficiency of one or more pituitary hormones. Few studies have explored the relative outcomes associated with conservative and neurosurgical intervention. METHODS: A retrospective evaluation of all patients with PA reviewed at Morriston Hospital was undertaken and diagnosis was obtained from Morriston database (Leicester Clinical Workstation database) between 1998 and 2019 from clinic letters and discharge summaries...

Introduction: Pituitary apoplexy (PA) is a rare phenomenon, characterized by a hemorrhagic or ischemic event of the pituitary gland, most often in association with a pituitary lesion. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the strain of virus responsible for the internationally recognized global pandemic COVID-19. Multiple clinical manifestations associated with this virus have been described, ranging from asymptomatic, mild flu symptoms to acute respiratory distress syndrome, end-organ failure leading to death...

Pituitary apoplexy means "sudden death" of the pituitary gland, usually caused by hemorrhage or infarction and often occurring in a pre-existing pituitary adenoma. In many cases, pituitary apoplexy is a medical and surgical emergency. Fast, efficient diagnosis and treatment are important in many cases. This case exemplifies an ideal lab workup and referral process to turn out best outcomes and prevent medical complications in our patient.

Initial treatment for prolactinoma is usually conservative with dopamine agonists. However, the duration of treatment is often lifelong and can be associated with significant side effects. Surgical outcomes are usually favorable and treatment complications low, raising the question whether surgical therapy should be included earlier in the treatment of prolactinoma. The aim of this study was to analyze the outcome of surgical resection of prolactinomas at our institution, to compare it with other published surgical and conservative series and to discuss the role of surgery in modern prolactinoma therapy...

Pituitary apoplexy is a rare condition that occurs due to acute haemorrhage in the pituitary gland and usually presents with features of acute hypopituitarism, visual defects and ophthalmoplegia. Pregnancy is one of the risk factors for pituitary apoplexy. Medical management is the first line of management in pregnancy irrespective of the gestational age. However, acute neuro-ophthalmological deterioration might warrant an urgent surgical decompression. Preoperative corticosteroids have dual benefits of providing hormonal replacement in the mother and also promoting fetal lung maturity in the offspring...

Our purpose is to provide new insights concerning the challenges of pituitary apoplexy in pregnancy (PAP) and the postpartum period (PAPP). This is a narrative review of the English literature using a PubMed search. The inclusion criteria were clinically relevant original studies (January 2012-December 2022). Overall, we included 35 original studies: 7 observational studies (selected cases on PA) and 28 case reports, including 4 case series (N = 49; PAP/PAPP = 43/6). The characteristics of PAP patients (N = 43) are as follows: maternal age between 21 and 41 (mean of 27...

OBJECTIVE: We aim to study the MRI features of pituitary adenoma (PA) apoplexy and their relationship with hypoxia, proliferation, and pathology. METHODS: Sixty-seven patients with MRI signs of PA apoplexy were selected. According to the MRI signs, they were divided into the parenchymal group and the cystic group. The parenchymal group had a low signal area on T2WI without cyst >2 mm and this area was not significantly enhanced on the corresponding TW1 enhancement...

BACKGROUND: Although conservative treatment is typically recommended for pregnant patients with pituitary adenoma (PA), surgical treatment is occasionally necessary for those with acute symptoms. Currently, surgical interventions utilized among these patients is poorly studied. AIM: To evaluate the surgical indications, timing, perioperative precautions and postoperative complications of PAs during pregnancy and to provide comprehensive guidance. METHODS: Six patients with PAs who underwent surgical treatment during pregnancy at Peking Union Medical College Hospital between January 1990 and June 2021 were recruited for this study...

Background  Pituitary apoplexy is a rare condition that usually occurs in the setting of a pituitary adenoma. It can present with symptoms of visual disturbances, vertigo, headache, and neurological impairments. Computed tomography (CT) scans can aid in identifying pituitary apoplexy and ruling out other diseases. We present a unique case of pituitary apoplexy in the setting of immune thrombocytopenic purpura (ITP). Case Description  A 61-year-old man with a past medical history significant for myocardial infarction presented to the emergency department with symptoms of diplopia and headache 36 hours after onset...

PURPOSE: To retrospectively summarize the clinical features of acromegaly complicated with fulminant pituitary apoplexy and analyze the prognostic factors to guide early identification and timely treatment of such patients. METHODS: A retrospective analysis was carried out to summarize the clinical manifestations, hormone changes, imaging, treatment and follow-up of ten patients with acromegaly complicated with fulminant pituitary apoplexy admitted to our hospital from February 2013 to September 2021...

The evolution of endoscopic trans-sphenoidal surgery raises the question of the role of transcranial surgery for pituitary tumors, particularly with the effectiveness of adjunct irradiation. This narrative review aims to redefine the current indications for the transcranial approaches for giant pituitary adenomas in the endoscopic era. A critical appraisal of the personal series of the senior author (O.A.-M.) was performed to characterize the patient factors and the tumor's pathological anatomy features that endorse a cranial approach...

Pituitary apoplexy (PA) is a possible complication of pituitary adenoma but is rarely followed by cerebral infarction. The mechanism by which this occurs is not totally understood but is believed to have multiple aetiologies such as arterial compression due to mass effect, vasospasm induced by the presence of blood or by vasoactive agents. In this report, we present a man in his 80s with known pituitary adenoma with a sudden onset of left central facial palsy, left hemiparesis, paresis of the VI left pair and previously unrecognised atrial fibrillation in the ECG...

BACKGROUND: Pituitary apoplexy (PA) is a clinical syndrome of pituitary hemorrhage or infarction and can result in hypopituitarism as well as compression of adjacent brain structures. Visual loss occurs frequently, as a result of tumor expansion and compression of the optic chiasm and optic nerves. Additionally, with pituitary tumor invasion into the fixed space of the cavernous sinus, compression of multiple cranial nerves can result in cavernous sinus syndrome (CSS). We describe a case of an undiagnosed pituitary tumor manifesting as abrupt PA with CSS during hemodialysis (HD)...

Pituitary apoplexy (PA) is a clinical syndrome resulting from sudden hemorrhage and/or infarction of the pituitary gland. Recent reports documented the development of PA secondary to treatment with gonadotropin-releasing hormone (GnRH) agonists for prostate cancer. A 52-year-old woman visited our emergency room with a severe headache, occurred 1 day prior. She underwent breast-conserving surgery for breast cancer 1 month prior. She was currently undergoing radiation and hormone therapy, consisting of leuprorelin...

SARS-CoV-2 vaccines are not free of side effects and most commonly affect the central or peripheral nervous system (CNS, PNS). This narrative review aims to summarise recent advances in the nature, frequency, management, and outcome of neurological side effects from SARS-CoV-2 vaccines. CNS disorders triggered by SARS-CoV-2 vaccines include headache, cerebro-vascular disorders (venous sinus thrombosis [VST], ischemic stroke, intracerebral hemorrhage, subarachnoid bleeding, reversible, cerebral vasoconstriction syndrome, vasculitis, pituitary apoplexy, Susac syndrome), inflammatory diseases (encephalitis, meningitis, demyelinating disorders, transverse myelitis), epilepsy, and a number of other rarely reported CNS conditions...

PURPOSE: Pituitary apoplexy can be a life threatening and vision compromising event. Antiplatelet and anticoagulation use has been reported as a contributing factor in pituitary apoplexy (PA). Utilizing one of the largest cohorts in the literature, this study aims to determine the risk of PA in patients on antiplatelet/anticoagulation (AP/AC) therapy. METHODS: A single center, retrospective study was conducted on 342 pituitary adenoma patients, of which 77 patients presented with PA (23%)...
