RESUMO

Pituitary apoplexy (PA) may be complicated by development of subarachnoid hemorrhage (SAH). We conducted a literature review to evaluate the rate of PA-associated tumor rupture and SAH. We conducted a systematic literature search (PubMed, Web of Science, Medline) for patients with PA-associated SAH and report a case SAH following PA. Suitable articles, case series, and case reports were selected based on predefined criteria following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). We reviewed included publications for clinical, radiological, surgical, and histopathological parameters.We present the case of a patient with PA developing extensive SAH whilst on the MRI who underwent delayed transsphenoidal resection. According to our literature review, we found 55 patients with a median age of 46 years; 18 (32.7%) were female. Factors associated with PA-related SAH were hypertension, diabetes mellitus, prior trauma, anticoagulant, and/or antiplatelet therapy. The most common presenting symptoms included severe headache, nausea and/or vomiting, impaired consciousness, and meningeal irritation. Acute onset was described in almost all patients. Twenty-two of the included patients underwent resection. In patients with available outcome, 45.1% had a favorable outcome, 10 (19.6%) had persisting focal neurological deficits, 7 developed cerebral vasospasms (12.7%), and 18 (35.3%) died. Mortality greatly differed between surgically (9.1%) and non-surgically (44.8%) treated patients. PA-associated SAH is a rare condition developing predominantly in males with previously unknown macroadenomas. Timely surgery often prevents aggravation or development of severe neuro-ophthalmological defects and improves clinical outcome.

RESUMO

CONTEXT: Pituitary apoplexy (PA) has been traditionally considered a neurosurgical emergency, yet retrospective single-institution studies suggest similar outcomes among patients managed medically. OBJECTIVE: We established a multicenter, international prospective registry to compare presentation and outcomes in PA patients treated with surgery or medical management alone. METHODS: A centralized database captured demographics, comorbidities, clinical presentation, visual findings, hormonal status, and imaging features at admission. Treatment was determined independently by each site. Key outcomes included visual, oculomotor, and hormonal recovery, complications, and hospital length of stay. Outcomes were also compared based on time from symptom onset to surgery, and from admission or transfer to the treating center. Statistical testing compared treatment groups based on 2-sided hypotheses and P less than .05. RESULTS: A total of 100 consecutive PA patients from 12 hospitals were enrolled, and 97 (67 surgical and 30 medical) were evaluable. Demographics, clinical features, presenting symptoms, hormonal deficits, and imaging findings were similar between groups. Severe temporal visual field deficit was more common in surgical patients. At 3 and 6 months, hormonal, visual, and oculomotor outcomes were similar. Stratifying based on severity of visual fields demonstrated no difference in any outcome at 3 months. Timing of surgery did not affect outcomes. CONCLUSION: We found that medical and surgical management of PA yield similar 3-month outcomes. Although patients undergoing surgery had more severe visual field deficits, we could not clearly demonstrate that surgery led to better outcomes. Even without surgery, apoplectic tumor volumes regress substantially within 2 to 3 months, indicating that surgery is not always needed to reduce mass effect.

RESUMO

In patients with pituitary adenomas, incidental intracranial aneurysms have been documented. Previous studies have highlighted the importance of preoperative imaging in these patients. However, imaging may be limited and fail to show the presence of vascular abnormalities. In this report, we discuss a case of a man in his 30s presenting with a newly diagnosed pituitary adenoma. CT and MRI, on admission, showed a pituitary mass with extension into the right cavernous sinus. After a sudden neurological deterioration, emergent CT/CT angiography revealed pituitary apoplexy with subarachnoid extension without vascular abnormalities. Successful emergency transsphenoidal hypophysectomy was followed by digital subtraction angiography which revealed the presence of two right supraclinoid internal carotid artery aneurysms. With this case, we aim to highlight the need for further vascular imaging in patients with pituitary apoplexy and subarachnoid haemorrhage, as preoperative imaging may be negative for vascular abnormalities especially in the setting of cavernous sinus invasion.

RESUMO

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. Total tumor volume (TTV), tumor extension volume (TEV), and suprasellar extension of tumor (SET) were calculated based on the lines drawn on MR images and compared between those who underwent ETSS only and those who underwent combined surgery. Results: Of 80 patients with GPAs, eight (10%) underwent combined surgery (seven in the same sitting and one had staged surgery). All eight patients (100%) who underwent combined surgery had tumors with multilobulations, extensions, and encasement of the vessels in the circle of Willis (COW). Of 72 patients who underwent ETSS alone, 21 (29.1%) had a multilobulated tumor, 26 (36.2%) tumors had anterior/lateral extensions, and 12 (16.6%) had encasement of the COW. The mean TTV, TEV, and SET for the combined surgery group were significantly higher than those in the ETSS group. None of the patients who underwent combined surgery suffered postoperative residual tumor apoplexy. Conclusion: Patients with GPAs in whom there are significant lateral intradural or subfrontal tumor extensions should be considered for combined surgery at the same sitting to avoid devastating postoperative apoplexy in the residual tumor, which can occur when ETSS alone is performed.

RESUMO

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. Uterine contractions should be monitored and tocolysis provided as per requirements in a post-viable fetus.

RESUMO

PURPOSE: To compare the clinical, hormonal, and radiological presentation and surgical outcomes of patients with macroadenomas presenting with pituitary apoplexy and patients not presenting pituitary apoplexy. METHODS: Multicentre retrospective study of patients presenting with macroadenomas and pituitary apoplexy in three Spanish tertiary hospitals between 2008 and 2022. We selected as control group (non-pituitary apoplexy), patients with pituitary macroadenomas without apoplexy who underwent pituitary surgery between 2008 and 2020. RESULTS: A total of 60 patients with apoplexy and 185 without apoplexy were enrolled. Patients with pituitary apoplexy were more frequently men (70% vs. 48.1%, p = 0.003), had higher prevalence of hypertension (43.3% vs. 26.0%, p = 0.011) and of obesity (23.3% vs. 9.7%, P = 0.007), were under treatment with anticoagulants more commonly (11.7% vs. 4.3%, P = 0.039) and had larger (27.5 ± 11.03 vs. 23.6 ± 12.55 mm, p = 0.035) and invasive pituitary macroadenomas more frequently (85.7% vs. 44.3%, P < 0.001) than those without apoplexy. Surgical remission was more frequent in patients with pituitary apoplexy than those without apoplexy (OR 4.55, P < 0.001), but they developed new pituitary deficits (OR 13.29, P < 0.001) and permanent diabetes insipidus (OR 3.40, P = 0.022) more commonly. However, visual improvement (OR 6.52, p < 0.001) and complete pituitary function recovery (OR 2.37, P < 0.001) was more common in patients without apoplexy. CONCLUSION: Surgical resection is more common in patients presenting with pituitary apoplexy than those without apoplexy; however, visual improvement and complete recovery of pituitary function is more common in patients without apoplexy. The risk of new pituitary deficits and permanent diabetes insipidus is higher in patients with apoplexy than in those without it.

RESUMO

OBJECTIVE: This study aimed to clarify the symptoms of pituitary or parasellar tumor onset with cranial nerve palsy (CNP) and to improve our knowledge of this rare symptom and its most appropriate treatment. METHODS: Among 1281 patients with pituitary or parasellar tumors surgically treated from 2003 to 2020, 30 cases (2.34%; 15 men and 15 women; mean age: 55.6 years, range: 6-83 years) first presenting with CNP were reviewed to evaluate the neurological symptoms, histological diagnosis, interval from onset to surgery, and time before complete CNP recovery. RESULTS: Pathological diagnoses comprised 17 pituitary adenomas, including 10 pituitary apoplexies and 4 adrenocorticotropic hormone-positive adenomas, and 13 other tumors, including 3 chordomas, 2 xanthogranulomas, 2 malignant lymphomas, 2 metastatic tumors, 1 Rathke cleft cyst, 1 plasmacytoma, 1 craniopharyngioma, and 1 neuroendocrine carcinoma. The mechanisms causing CNP were pituitary apoplexy (n = 10), cranial nerve compression or involvement (n = 17), and inflammatory changes (n = 9). As the first manifestation, 20 (66.7%) patients presented with oculomotor nerve palsy, 2 (6.7%) with trochlear nerve palsy, and 13 (43.3%) with abducens nerve palsy. Full recovery of CNP was obtained in 25 patients (83.3%) after surgery alone and in 2 patients (6.7%) after adjuvant therapy. Early surgery provided no significant difference in full recovery rates although it reduced the time to reach full recovery. CONCLUSIONS: It is critical to determine the mechanisms of CNP and intervene surgically to improve symptoms, shorten the duration of the disorder, prevent relapses, and obtain the correct pathological diagnosis to select the proper adjuvant therapy.

RESUMO

BACKGROUND: Pituitary apoplexy is acute infarction with or without hemorrhage of the pituitary gland. It is a rare but potentially life-threatening emergency that most commonly occurs in the setting of pituitary adenoma. The mechanisms underlying pituitary apoplexy are not well understood, but are proposed to include factors of both hemodynamic supply and adenoma demand. In the case of patients with known pituitary macroadenomas undergoing major surgery for other indications, there is a theoretically increased risk of apoplexy in the setting of "surgical stress." However, risk stratification of patients with nonfunctioning pituitary adenomas prior to major surgery is challenging because the precipitating factors for pituitary apoplexy are not completely understood. Here we present a case in which intraoperative hypovolemia is a possible mechanistic precipitating factor for pituitary apoplexy. CASE PRESENTATION: A 76-year-old patient with a known hypofunctioning pituitary macroadenoma underwent nephrectomy for renal cell carcinoma, during which there was significant intraoperative blood loss. He became symptomatic with ophthalmoplegia on the second postoperative day, and was diagnosed with pituitary apoplexy. He was managed conservatively with cortisol replacement therapy, and underwent therapeutic anticoagulation 2 months after pituitary apoplexy for deep vein thrombosis. His ophthalmoplegia slowly resolved over months of follow-up. Pituitary apoplexy did not recur with therapeutic anticoagulation. CONCLUSIONS: When considering the risk of surgery in patients with a known pituitary macroadenoma, an operation with possible high-volume intraoperative blood loss may have increased risk of pituitary apoplexy because intraoperative hypovolemia may precipitate ischemia, infarction, and subsequent hemorrhage. This may be particularly relevant in the cases of elective surgery. Additionally, we found that we were able to therapeutically anticoagulate a patient 2 months after pituitary apoplexy for the management of deep vein thrombosis without recurrence of pituitary apoplexy.

RESUMO

Tension pneumosella has been recognized as a very rare complication of pituitary transsphenoidal surgery. To the best of our knowledge, we report the second case of a pituitary adenoma "pneumo-apoplexy", which is characterized by findings consistent with tension pneumosella in the context of apoplexy of a pituitary adenoma; although it is an extremely rare diagnosis, it should be considered in patients with compatible clinical and radiological findings, particularly with a previous history of transsphenoidal pituitary surgery.

RESUMO

BACKGROUND: Brain stroke is a rare, life-threatening condition associated with pituitary apoplexy (PA), resulting from direct arterial occlusion due to mechanical compression secondary to the sudden enlargement of the pituitary adenoma, or to vessel vasospasm, induced by tumor hemorrhage. CASE REPORT: We report the case of a 64-year-old woman with PA complicated by bilateral anterior circulation stroke due to critical stenosis of both anterior cerebral arteries (ACA). Despite the quick surgical decompression and consequent blood flow restoration, the neurological conditions of the patient did not improve and she died 18 days later. Ten other cases of anterior circulation stroke due to PA were retrieved in a systematic review of literature. Clinical and neuroradiological features of these patients and treatment outcome were assessed to suggest the most proper management. CONCLUSION: The onset of neurological symptoms suggestive for brain stroke in patients with PA requires performing an emergency Magnetic Resonance Imaging (MRI), including Diffusion-weighted and angiographic MR-sequences. The role of surgery in these cases is debated, however, transsphenoidal adenomectomy would permit us to decompress the ACA and restore blood flow in their territories. Although the prognosis of PA-induced anterior circulation stroke is generally poor, a timely diagnosis and treatment would be paramount for improving patient outcome.

RESUMO

BACKGROUND AND IMPORTANCE: Chordomas are centrally located, expansile soft tissue neoplasms that arise from the remnants of the embryological notochord. Hemorrhagic presentation is exceedingly rare and can resemble pituitary apoplexy. Moreover, a purely intrasellar location of a chordoma is extremely uncommon. We report a case of a hemorrhagic intrasellar chordoma in an adult male, which presented similarly to pituitary apoplexy and was resolved with surgical resection. CLINICAL PRESENTATION: A 69-year-old male presented with a 4 week history of acute onset headache and concurrent diplopia, with significantly reduced testosterone and slightly reduced cortisol. His left eye demonstrated a sixth cranial nerve palsy. Magnetic resonance imaging of the brain showed a large hemorrhagic mass in the pituitary region with significant compression of the left cavernous sinus and superior displacement of the pituitary gland. The patient underwent an endoscopic endonasal transsphenoidal approach for the resection of the lesion. Near total resection was achieved. Final pathology revealed chordoma with evidence of intratumoral hemorrhage, further confirmed by immunopositive stain for brachyury. Post-operatively, the patient had improved diplopia and was discharged home on low dose hydrocortisone. At 3-month follow-up, his diplopia was resolved and new MRI showed stable small residual disease. CONCLUSIONS: Apoplectic chordomas are uncommon given chordoma's characteristic lack of intralesional vascularity and represent a diagnostic challenge in the sellar region. Our unique case demonstrates that despite our initial impression of pituitary apoplexy, this was ultimately a case of apoplectic chordoma that responded well to endoscopic endonasal surgery.

RESUMO

BACKGROUND: Pituitary-dependent hypercortisolism (PDH) is one of the most common endocrine disorders in veterinary medicine. However, there are few reports on pituitary tumor apoplexy (PTA) in dogs and no reports on its surgical intervention in veterinary medicine. Accordingly, the appropriate treatment is unknown. Herein, a case of PDH and PTA in a dog treated surgically is described. CASE PRESENTATION: A mongrel female dog (spayed; age, 8 years and 8 months; weight, 6.1 kg) with persistently elevated alkaline phosphatase underwent adrenocorticotropic hormone (ACTH) stimulation testing (post-stimulation cortisol: 20.5 µg/dL), abdominal ultrasonography (adrenal gland thickness: left, 5.7 mm; right, 8.1 mm), and brain magnetic resonance imaging (MRI) (pituitary-to-brain ratio [PBR], 0.61) at the referral hospital, resulting in a diagnosis of PDH (day 0). On day 9, the dog visited XXXX for the preparation of pituitary surgery to treat PDH. However, on days 10-15, the dog developed a loss of energy and appetite, bloody diarrhea, vomiting, and a decreased level of consciousness. However, on day 16, the dog's condition recovered. A preoperative MRI scan performed on day 52 (the day of surgery) showed apoplexy in the dorsal pituitary region (PBR, 0.68). Based on the PTA findings, the risks of surgery were described to the owner, and approval was obtained. At the time of trans-sphenoidal surgery, a partial pituitary resection was performed with preservation of the PTA area due to adhesions between the PTA area of the right side of the pituitary and surrounding tissues. The resected pituitary tissue was diagnosed as an ACTH-producing adenoma, with necrotic and hemorrhagic findings. As of day 290, endogenous ACTH and cortisol levels did not exceed the reference range. CONCLUSIONS: The acute signs that occurred on days 10-15 were most likely caused by PTA. Therefore, when signs similar to those detected in acute hypoadrenocorticism are observed in dogs with PDH, it is necessary to include PTA as a differential diagnosis. Trans-sphenoidal surgery may be effective in PDH-affected dogs that develop PTA, but careful attention should be paid to tissue adhesions secondary to hemorrhage that may occur after PTA.

RESUMO

Pituitary apoplexy is a rare but potentially fatal endocrinological emergency which can be difficult to diagnose as presenting symptoms vary significantly. Optimal management requires early diagnosis and collaboration between ophthalmology, endocrinology and neurosurgical services. We present a case of pituitary apoplexy in a 52-year-old Caucasian female who was referred by her optometrist to Palmerston North Hospital Eye Clinic with a three-week history of sudden onset moderate bifrontal headaches, two weeks of non-specific peripheral visual changes and dense bitemporal inferior quadrantanopia on formal visual field testing. Ocular motility and slit lamp examination were unremarkable and retinal nerve fibre layer (RNFL) was relatively preserved on optical coherence tomography (OCT). MRI demonstrated a haemorrhagic pituitary macroadenoma elevating and compressing the optic chiasm without cavernous extension. Blood tests revealed mild hypothyroidism, hypocortisolism, hypogonadotropism and hyperprolactinaemia. The patient was commenced on hydrocortisone and levothyroxine replacement and proceeded for urgent transsphenoidal tumour resection at Wellington Regional Hospital. Histology revealed a non-functioning macroadenoma. The patient was asymptomatic and visual field tests had normalised three weeks post-operatively. Six weeks post-operatively, thyroid function and cortisol levels were normal and replacement therapies were ceased.

RESUMO

Pituitary tumor apoplexy (PTA) classically comprises sudden-onset headache, loss of vision, ophthalmoparesis, and decreased consciousness. It typically results from hemorrhage and/or infarction within a pituitary adenoma. Presentation is heterologous, and optimal management is debated. The time course of recovery of cranial nerve deficits (CNDs) and headaches is not well established. In this study, a retrospective series of consecutive patients with PTA managed at a single academic institution over a 22-year period is presented. Headaches at the time of surgery were more severe in the early and subacute surgical cohort and improved significantly within 72 h postoperatively (p < 0.01). At one year, 90% of CNDs affecting cranial nerves (CNs) 3, 4, and 6 had recovered, with no differences between early (<4 d), subacute (4−14 d), and delayed (>14 d) time-to-surgery cohorts. Remarkably, half recovered within three days. In total, 56% of CN2 deficits recovered, with the early surgery cohort including more severe deficits and recovering at a lower rate (p = 0.01). No correlation of time-to-surgery and rapidity of recovery of CNDs was observed (p = 0.65, 0.72). Surgery for PTA is associated with rapid recovery of CNDs in the early, subacute, and delayed time frames, and with rapid headache improvement in the early and subacute time frames in 50% or more of patients.

RESUMO

BACKGROUND: Pituitary apoplexy is an emergent and potential life-threatening complication of pituitary adenomas if not managed properly. The aim of our study is to present our series of pituitary adenomas and to focus on the clinical, radiological, and surgical characteristics of this rare complication. METHODS: In this study, a total of 143 patients with pituitary adenoma underwent surgical treatment between 2016 and 2018. All patients were operated using endoscopic endonasal transsphenoidal (EET) technique. The data of pituitary apoplexy cases were recorded. Resection rates, hormonal results, and visual outcomes of patients with pituitary apoplexy were evaluated. RESULTS: Of the 143 patients, 8 (5.59%) were presented with the symptoms and radiological findings of pituitary apoplexy. The mean age was 26.75 years, and 4 (50%) of them were male and 4 were female. Pre-operative mean Knosp grading score was 2.1 All of eight patients underwent emergent surgical intervention and total resection was achieved in 75% of patients with apoplexy. Hormone levels were significantly decreased after surgery (p<0.05), except prolactin (p>0.05). Cerebrospinal fluid leakage occurred in one pa-tient. None of the patient with pituitary apoplexy died in our series. CONCLUSION: Pituitary apoplexy is an important complication of pituitary adenomas. Early diagnosis and surgical intervention provide excellent ophthalmological and hormonal outcomes. Emergent EET approach is crucial for patients with ophthalmological findings and macroadenomas.

RESUMO

BACKGROUND: Distant spread of pituitary adenoma outside the sellar/suprasellar region is classified as pituitary carcinoma. Cerebrospinal fluid (CSF)-born spread of pituitary adenoma can occur after tumor cell spillage into the CSF space after surgery, irradiation, or apoplexy and is not necessarily related to intrinsic tumor biology. OBJECTIVE: To systematically review the literature and describe the clinical characteristics and treatment strategies of patients with pituitary carcinomas. We further present 2 cases from our institution. METHODS: A single-center retrospective review of patients with pituitary adenoma spread to distant intracranial locations between 2000 and 2020 was performed. Electronic databases were searched from their inception to May 25, 2021, and studies describing patients with pituitary spread to distant locations were included. RESULTS: Of 1210 pituitary adenoma cases reviewed, 2 (0.16%) showed tumor spread to distant locations. We found 134 additional cases (from 108 published articles) resulting in a total of 136 cases (61.9% were male). The time to tumor spread ranged between 0 and 516 months (median: 96 months). The follow-up duration ranged between 0 and 240 months (median: 11.5 months). All but 2 patients (98.5%) underwent surgical resection before adenoma spread. The 2 exceptions included a patient with evidence of an apoplectic event on autopsy and another patient with leptomeningeal pituitary spread but an unclear history of apoplexy. Elevated tumor markers were not linked to poor outcomes. CONCLUSION: Distant spread of pituitary adenoma may occur after surgery, irradiation, or apoplexy. It is not necessarily associated with a malignant clinical course.

RESUMO

INTRODUCTION: Depending on severity of presentation, pituitary apoplexy can be managed with acute surgery or non-operatively. We aim to assess long-term tumour control, visual and endocrinological outcomes following pituitary apoplexy with special emphasis on patients treated non-operatively. METHODS: Multicentre retrospective cohort study. All patients with symptomatic pituitary apoplexy were included. Patients were divided into 3 groups: group 1: surgery within 7 days; group 2: surgery 7 days-3 months; group 3: non-operative. Further intervention for oncological reasons during follow-up was the primary outcome. Secondary outcome measures included visual and endocrinological function at last follow-up. RESULTS: One hundred sixty patients were identified with mean follow-up of 48 months (n = 61 group 1; n = 34 group 2; n = 64 group 3). Factors influencing decision for surgical treatment included visual acuity loss (OR: 2.50; 95% CI: 1.02-6.10), oculomotor nerve palsy (OR: 2.80; 95% CI: 1.08-7.25) and compression of chiasm on imaging (OR: 9.50; 95% CI: 2.06-43.73). Treatment for tumour progression/recurrence was required in 17%, 37% and 24% in groups 1, 2 and 3, respectively (p = 0.07). Urgent surgery (OR: 0.16; 95% CI: 0.04-0.59) and tumour regression on follow-up (OR: 0.04; 95% CI: 0.04-0.36) were independently associated with long-term tumour control. Visual and endocrinological outcomes were comparable between groups. CONCLUSION: Urgent surgery is an independent predictor of long-term tumour control following pituitary apoplexy. However, 76% of patients who successfully complete 3 months of non-operative treatment may not require any intervention in the long term.

RESUMO

Pituitary apoplexy (PA) is a clinical diagnosis comprising a sudden onset of headache, neurological deficits, endocrine disturbances, altered consciousness, visual loss, or ophthalmoplegia. However, clinically, the presentation of PA is extremely variable and occasionally fatal. While meningitis and cerebral infarcts are themselves serious diseases, they are rarely seen as manifestations of PA and are exceedingly rare when present together. We present the case of a 20-year-old male with a rapid progression of symptoms of meningitis, PA and stroke. The present article seeks to emphasize a rare manifestation of PA with an attempt to understand the intricacies of its evaluation and management.
