Efficacy of GnRH Pulses in Hypogonadism Secondary to Primary Empty Sella: Case Report.

This study aims to assess the effectiveness of pulsed gonadotropin-releasing hormone (GnRH) micropump replacement therapy in the treatment of hypogonadotropic hypogonadism (HH) caused by primary empty sella (PES).The efficacy of pulsed GnRH replacement therapy using the micropump was evaluated in a middle-aged male patient with HH who had experienced the loss of his only child. Relevant literature was also consulted to compare the differences between pulse GnRH treatment and conventional treatment in terms of the development of secondary sexual characteristics, sex hormone levels, sperm production rate, and sperm activity rate in male patient with HH.In this report, a 45-year-old male diagnosed with HH and PES presented with fatigue and decreased libido. The main characteristics included decreased follicle stimulating hormone (FSH) levels of 0.03 mIU/mL, luteinizing hormone (LH) levels of 0.02 mIU/mL, and testosterone (T) levels of 0.72 nmol/L. Magnetic resonance imaging (MRI) revealed an empty sella. Semen analysis showed a small number of normal sperm with reduced motility. During treatment with the micropump pulse GnRH, the patient experienced no side effects and showed improvements in fatigue, reduced libido, sexual urge, anxiety, and feelings of inferiority. LH, FSH, and T levels returned to normal, while sperm activity rate increased to 79.9%. Ultimately, the patient's spouse achieved a natural pregnancy.Pulsed gonadotropin delivery using the micropump demonstrates good efficacy and tolerability, and aligns more closely with the physiological rhythm of GnRH secretion in the human body.

Infections and gender: clues for diagnosis of adrenal insufficiency-a case report and a review of the literature.

The clinical presentation of adrenal insufficiency, a condition causing adrenal hormone deficiency, is characterised by non-specific symptoms and signs: consequently, an important diagnostic delay is often evident which correlates with an increased mortality. This case report shows how the clustering of some symptoms and signs may hamper the diagnostic suspicion for this condition: serum electrolyte alterations and weight loss, when associated to recurrent infections and, in female patients, an empty sella may further guide the clinician towards a diagnosis of adrenal insufficiency. Accordingly, a clinical approach taking into account gender medicine could improve the diagnostic workup.

Unveiling the domino effect: a nine-year follow-up on pentalogy of central nervous system induced by a large unruptured cerebral arteriovenous malformation: a case report and literature review.

Background: The disruption of intracranial fluid dynamics due to large unruptured cerebral arteriovenous malformation (AVM) commonly triggers a domino effect within the central nervous system. This phenomenon is frequently overlooked in prior clinic and may lead to catastrophic misdiagnoses. Our team has documented the world's first case of so-called AVM Pentalogy (AVMP) induced by a AVM. Clinical presentation and result: A 30-year-old female was first seen 9 years ago with an occasional fainting, at which time a huge unruptured AVM was discovered. Subsequently, due to progressive symptoms, she sought consultations from several prestigious neurosurgical departments in China, where all consulting neurosurgeons opted for conservation treatment due to perceived surgical risks. During the follow-up period, the patient gradually presented with hydrocephalus, empty sella, secondary Chiari malformation, syringomyelia, and scoliosis (we called as AVMP). When treated in our department, she already displayed numerous symptoms, including severe intracranial hypertension. Our team deduced that the hydrocephalus was the primary driver of her AVMP symptoms, representing the most favorable risk profile for intervention. As expected, a ventriculoperitoneal shunt successfully mitigated all symptoms of AVMP at 21-months post-surgical review. Conclusion: During the monitoring of unruptured AVM, it is crucial to remain vigilant for the development or progression of AVMP. When any component of AVMP is identified, thorough etiological studies and analysis of cascade reactions are imperative to avert misdiagnosis. When direct AVM intervention is not viable, strategically addressing hydrocephalus as part of the AVMP may serve as the critical therapeutic focus.

Clinical value of neuroimaging indicators of intracranial hypertension in patients with cerebral venous thrombosis.

PURPOSE: Intracranial hypertension (IH) frequently complicates cerebral venous thrombosis (CVT). Distinct neuroimaging findings are associated with IH, yet their discriminative power, reversibility and factors favoring normalization in prospective CVT patients are unknown. We determined test performance measures of neuroimaging signs in acute CVT patients, their longitudinal change under anticoagulation, association with IH at baseline and with recanalization at follow-up. METHODS: We included 26 consecutive acute CVT patients and 26 healthy controls. Patients were classified as having IH based on CSF pressure > 25 cmH2O and/or papilledema on ophthalmological examination or ocular MRI. We assessed optic nerve sheath diameter (ONSD), optic nerve tortuousity, bulbar flattening, lateral and IVth ventricle size, pituitary configuration at baseline and follow-up, and their association with IH and venous recanalization. RESULTS: 46% of CVT patients had IH. ONSD enlargement > 5.8 mm, optic nerve tortuousity and pituitary grade ≥ III had highest sensitivity, ocular bulb flattening and pituitary grade ≥ III highest specificity for IH. Only ONSD reliably discriminated IH at baseline. Recanalization was significantly associated with regressive ONSD and pituitary grade. Other neuroimaging signs tended to regress with recanalization. After treatment, 184.9 ± 44.7 days after diagnosis, bulbar flattening resolved, whereas compared with controls ONSD enlargement (p < 0.001) and partially empty sella (p = 0.017), among other indicators, persisted. CONCLUSION: ONSD and pituitary grading have a high diagnostic value in diagnosing and monitoring CVT-associated IH. Given their limited sensitivity during early CVT and potentially persistent alterations following IH, neuroimaging indicators can neither replace CSF pressure measurement in diagnosing IH, nor determine the duration of anticoagulation.

Empty sella in somatotropic pituitary adenomas; a series of 23 cases.

Purpose: We aimed to investigate empty sella syndrome in somatotrophic pituitary adenoma for possible etiology, complications, and treatment options. Method: Among over 2,000 skull base masses that have been managed in our center since 2013, we searched for growth hormone-producing adenomas. Clinical, surgical, and imaging data were retrospectively collected from hospital records to check for sella that lacked pituitary tissue on routine imaging. Result: In 220 somatotrophic adenomas, 23 patients had an empty sella with surgical and follow-up data. The mean age of the sample was 46 years with the same male-to-female ratio. Five cases had partial empty sella and the rest were complete empty sellas. The most common simultaneous hormonal disturbance was high prolactin levels. Six had adenoma invasion into the clivus or sphenoid sinus and 10 had cavernous sinus intrusion. Peri-operative low-flow and high-flow cerebrospinal fluid (CSF) leaks were encountered in one and two patients, respectively, which were successfully sealed by abdominal fat. The majority of cases required growth hormone replacement therapy while it was controlled without any replacement therapy in nine patients. No pituitary hormonal disturbance occurred after transsphenoidal surgery except for hypothyroidism in one patient. Conclusion: An empty sella filled with fluid can be detected frequently in pituitary adenomas, especially in the setting of acromegaly. The pituitary gland may be pushed to the roof of the sella and might be visible as a narrow rim on imaging or may be detected in unusual places out of the sella. The pathophysiology behind such finding originates from soft and hard tissue changes and CSF pressure alternations during abundant growth hormone production.

A Comprehensive Review of Empty Sella and Empty Sella Syndrome.

OBJECTIVE: Incidental radiographic findings of an empty sella are prevalent in up to 35% of the general population. While empty sella was initially considered clinically insignificant, a subset of patients exhibits endocrine or neuro-ophthalmologic manifestations which are diagnostic of empty sella syndrome (ESS). Recent studies suggest that more patients are affected by ESS than previously recognized, necessitating a deeper understanding of this condition. This comprehensive review describes a practical approach to evaluating and managing ESS. METHODS: Literature review was conducted on etiologies and risk factors associated with primary and secondary empty sella, the radiologic features that differentiate empty sella from other sellar lesions, and the role of clinical history and hormone testing in identifying patients with ESS, as well as treatment modalities. RESULTS: Pituitary function testing for somatotroph, lactotroph, gonadotroph, corticotroph, and thyrotroph abnormalities is necessary when suspecting ESS. While an isolated empty sella finding does not require treatment, ESS may require pharmacologic or surgical interventions to address hormone deficits or intracranial hypertension. Targeted hormone replacement as directed by the endocrinologist should align with guidelines and patient-specific needs. Treatment may involve a multidisciplinary collaboration with neurology, neurosurgery, or ophthalmology to address patient symptoms. CONCLUSION: This review underscores the evolving understanding of ESS, stressing the significance of accurate diagnosis and tailored management to mitigate potential neurologic and endocrine complications in affected individuals.

Heritable Pulmonary Arterial Hypertension in a Patient With Empty Sella Syndrome: A Case Report.

Pulmonary arterial hypertension (PAH) is a progressive disease with multiple contributing factors. Genetics, epigenetics, hormonal, and immune factors all contribute to the development and progression of the disease. A number of endocrine disorders and metabolic syndromes are being studied for their potential role in the development of PAH. We report to you a case of a 32-year-old female with a rare presentation of a non-BMPR2 mutation heritable PAH complicated with empty sella syndrome and panhypopituitarism.

Incidental Petrous Apex Cephalocele Presenting With Transient Global Amnesia: A Case Report and Rapid Literature Review.

Transient global amnesia (TGA) constitutes a rare clinical entity that manifests with temporary memory without any other neurological manifestation. Several pathogenetic mechanisms have been implicated, including temporal hypoperfusion, venous congestion, and cortical spreading potentials. Accordingly, the only relevant imaging findings are hippocampal CA1 areas of restricted diffusion on diffusion-weighted images. In the current case report, we present the rare case of a patient with TGA associated with bilateral petrous apex cephalocele (PAC). A 63-year-old female presented with a single episode of transient memory. The brain MRI showed a bilateral PAC and an empty sella. The patient was neurologically intact upon examination and was conservatively managed. There was no symptom recurrence during the six months of follow-up. We hypothesize that the presence of the meningocele could be associated with the pathogenesis of TGA. To the best of our knowledge, this is the first case of a petrous apex meningocele presenting with TGA. Most previously reported patients were females in their fourth decade of life, usually presenting with headaches or incidentally. Almost half of the cases were bilateral, with an empty sella. Surgical treatment was reserved for symptomatic patients with cerebrospinal fluid leaks and excruciating trigeminal neuralgia. Patients with TGA may be associated with temporal lesions, including PAC. Likewise, PAC is an extremely rare clinical entity that could occasionally present with TGA.

Normative body mass-adjusted reference ranges of magnetic resonance imaging signs commonly used in diagnosing idiopathic intracranial hypertension in a healthy standard population.

Patients with chronic daily headaches (CDH) are often a diagnostic challenge and frequently undergo neuroimaging. One common underlying cause of CDH is idiopathic intracranial hypertension (IIH). However, certain neuroimaging abnormalities that suggest IIH, such as optic nerve sheath diameters (ONSD), pituitary gland height, and venous sinus diameter, require interpretation due to the absence of established normative values. Notably, intracranial pressure is known to varies with age, sex and weight, further complicating the determination of objectively abnormal findings within a specific patient group. This study aims to assist clinical neuroradiologists in differentiating neuroimaging results in CDH by providing weight-adjusted normative values for imaging characteristics of IIH. In addition to age and BMI we here assessed 1924 population-based T1-weighted MRI datasets of healthy participants for relevant MRI aspects of IIH. Association to BMI was analyzed using linear/logistic regression controlled for age and stratified for sex. ONSD was 4.3 mm [2.8; 5.9]/4.6 mm [3.6; 5.7] and diameter of transverse sinus was 4.67 mm [1.6; 6.5]/4.45 mm [3.0; 7.9]. Height of pituitary gland was 5.1 mm [2.2;8.1]/4.6 mm [1.9;7.1] for female and male respectively. Values generally varied with BMI with regression slopes spanning 0.0001 to 0.05 and were therefor presented as normative values stratified by BMI. Protrusion of ocular papilla, empty sella and transverse sinus occlusion were rare in total. Our data show an association between BMI and commonly used MRI features for diagnosing IIH. We provide categorized normative BMI values for ONSD, pituitary gland height, and transverse sinus diameter. This distinction helps objectively identify potential IIH indicators compared to regular population norms, enhancing diagnostic accuracy for suspected IIH patients. Notably, optic nerve head protrusion, empty sella, and transverse sinus occlusion are rare in healthy individuals, solidifying their importance as imaging markers regardless of BMI.

Ectopic pituitary adenoma with empty sella: A case report.

Ectopic pituitary adenoma is a condition characterized by the presence of an adenoma originating from extra-sellar pituitary cell residue from the migration of Rathke's pouch. First described in 1909, ectopic pituitary adenoma is a very rare, largely unknown condition with a challenging diagnosis, that requires proving the absence of communication between the extra-sellar mass and the normal pituitary gland (or any of the intra-sellar contents). Here, we describe the case of a 38-year-old female who presented with symptomatic hyperprolactinemia in whom magnetic resonance imaging revealed a space-occupying mass in the sphenoid sinus with an empty sella turcica. Clinical information coupled with magnetic resonance imaging findings raised suspicion for the diagnosis, which was later confirmed through surgery (showing the absence of a breach in the sellar floor dura), and histology. Given the rarity of such cases, management is not standardized; however, most patients reported in the literature, as in our case, have undergone surgical treatment. This case report aims to provide an additional example to the existing literature on this rare condition, especially when it is associated with an empty sella turcica.

Pituitary Dysfunction in Idiopathic Intracranial Hypertension: An Analysis of 80 Patients.

BACKGROUND: Empty sella is a commonly described imaging entity in patients with idiopathic intracranial hypertension (IIH). Though menstrual and hormonal disturbances have been associated with IIH, available literature lacks systematic analysis of pituitary hormonal disturbances in IIH. More so, the contribution of empty sella in causing pituitary hormonal abnormalities in patients of IIH has not been described. We carried out this study to systematically assess the pituitary hormonal abnormalities in patients with IIH and its relation to empty sella. METHODS: Eighty treatment naïve patients of IIH were recruited as per a predefined criterion. Magnetic resonance imaging (MRI) brain with detailed sella imaging and pituitary hormonal profile were done in all patients. RESULTS: Partial empty sella was seen in 55 patients (68.8%). Hormonal abnormalities were detected in 30 patients (37.5%), reduced cortisol levels in 20%, raised prolactin levels in 13.8%, low thyroid-stimulating hormone (TSH) levels in 3.8%, hypogonadism in 1.25%, and elevated levels of gonadotropins were found in 6.25% of participants. Hormonal disturbances were independent and were not associated with the presence of empty sella (p = 0.493). CONCLUSION: Hormonal abnormalities were observed in 37.5% patients with IIH. These abnormalities did not correlate with the presence or absence of empty sella. Pituitary dysfunction appears to be subclinical in IIH and responds to intracranial pressure reduction, not requiring specific hormonal therapies.

Idiopathic intracranial hypertension associated with polycystic ovarian syndrome, sensorineural hearing loss, and elevated inflammatory markers that lead to bilateral blindness: A case report with literature review.

Background: Pseudotumor cerebri (PTC) or idiopathic intracranial hypertension (IIH) is characterized by elevated intracranial pressure without hydrocephalus or mass lesion, with normal cerebrospinal fluid (CSF) studies and neuroimaging. The exact cause remains uncertain, but potential mechanisms include increased CSF production, impaired CSF absorption, cerebral edema, and abnormal cerebral venous pressure gradients. Patients may present with various accompanying symptoms such as unilateral or bilateral visual obscuration, pulsatile tinnitus, back pain, dizziness, neck pain, blurred vision, cognitive difficulties, radicular pain, and typically intermittent horizontal diplopia. Case Description: We report a case of a 32-year-old female who initially presented with chronic headaches and oligomenorrhea, which resulted in the diagnosis of polycystic ovary syndrome (PCOS) a few years before the initial diagnosis of PTC. Despite receiving maximum medical treatment and undergoing optic nerve sheath fenestration, the patient experienced complete bilateral vision loss. Nearly 5 years later, the patient sought care at our outpatient neurology clinic, presenting with symptoms including tinnitus, left-sided hearing loss, and joint pain with elevated inflammatory markers and headaches. The focus of this research was to discuss the pathophysiology of each of these comorbidities. Conclusion: This case report aims to explore the pathophysiological relationships between PTC and concurrent comorbidities, including PCOS, sensorineural hearing loss, empty sella (ES) syndrome, and elevated inflammatory markers. Remarkably, no other PTC case with this unique constellation of concurrent comorbidities have been reported in existing medical literature. The case report underscores the critical importance of early diagnosis of IIH and prompt medical intervention, particularly in patients with PCOS experiencing chronic headaches.

The 1 µg Synacthen stimulation test in the diagnosis of secondary adrenal insufficiency in patients with Rathke's cleft cyst and empty sella syndrome.

INTRODUCTION: Rathke's cleft cyst (RCC) and primary empty sella syndrome (PESS) are usually incidental findings on magnetic resonance imaging (MRI) scans. In most cases, these lesions do not cause mass effect symptoms and do not require surgical intervention. In patients with RCC or PESS, it is important to exclude secondary adrenal insufficiency (SAI), which may be a life-threatening condition. MATERIAL AND METHODS: The incidence of SAI was assessed in patients with RCC or PESS detected by MRI, using the 1 µg Synacthen stimulation test. A total of 38 patients were analysed. Test results were linked to clinical symptoms and the type of cystic lesion. RESULTS: Assuming that cortisol levels < 14.6 µg/dL in Synacthen test are the criterion of SAI diagnosis, SAI was diagnosed only in 2 patients (5%). Adopting the traditional criterion of cortisol levels < 18 µg/dL, SAI would be diagnosed in 7 patients (18.4 %). Dizziness (Chi2 = 3.89; p = 0.049) and apathy (Chi2 = 3.87; p = 0.049) were significantly more frequent in the PESS group than in the RCC group. CONCLUSIONS: The incidence of SAI in the general patient population with empty sella syndrome and Rathke's cleft cysts is low. The 1 µg Synacthen test seems to be a valuable tool in the diagnosis of SAI among patients with RCC and PESS. Further studies are necessary to determine the sensitivity and specificity of the 1 µg Synacthen test with the standardization of test protocol and considering the cortisol level at the 20-minute timepoint. PESS patients report dizziness and apathy more frequently than RCC patients, which does not result from the disturbance of the hypothalamic-pituitary-adrenal axis, but probably from the different pathogenesis of these cystic lesions.

Sheehan's Syndrome in India: Clinical Characteristics and Laboratory Evaluation.

Background: Sheehan's Syndrome (SS) is an important cause of hypopituitarism especially in developing countries though it remains underdiagnosed to a great extent. Torrential bleeding after delivery followed by lactation failure and amenorrhoea gives a clue to the diagnosis which is usually made after several years of delivery. Materials and Methods: It was a retrospective observational study conducted by reviewing the case records of 38 cases of SS. The age, anthropometric measurements, signs and symptoms, biochemical parameters, hormone levels and imaging reports were examined and analyzed. Results: The mean age at presentation was 36.5 years because there was a delay of 8.4 years from last delivery before diagnosis could be made. Ninety percent patients presented with lactation failure. Anaemia, hypotension, hypogonadism, hypothyroidism, and altered lipid profile were the most common findings. The mean systolic blood pressure (BP) was 80.95 mm and diastolic BP was 51.6 mm of Hg at the time of presentation. Hyponatremia was the most common electrolyte abnormality noted and low HDL was the commonest lipid abnormality. Conclusion: A large percentage of patients presented with amenorrhea, lactation failure, and decreased or absent axillary/pubic hair. Shock, anemia, and hyponatremia were also common symptoms among the patients studied. The diagnosis of SS rests upon a thorough history taking of the postpartum events in cases presenting with hypopituitarism irrespective of the age at presentation. Proper antenatal care with exclusive institutional deliveries can reduce the prevalence of SS in developing countries.

Retrospection of Seldom-Known Causes and Presentations of Partial Empty Sella Syndrome.

Pituitary gland shrinkage or flattening obscures it from view on an MRI, giving the impression that it is an empty sella. On the other hand, if some viable pituitary gland tissue is still seen on the MRI scan, a diagnosis of partial empty sella can be made. Diminished physiological and functional reserve in the elderly can result in a bad prognosis if not treated early. Therefore, there is a need to become familiar with fewer known causes and presentations of the empty sella or partial empty sella syndrome in older patients. We report a case of a 71-year-old female with multiple known ailments presenting with hypotension as the sole symptom. It urged us to investigate further and reach the root cause as partial empty sella syndrome with panhypopituitarism.

Hyponatremia due to adrenal insufficiency after a Mamushi bite: a case report.

BACKGROUND: Mamushi bites are the most common venomous snake bites in Japan, with known complications including rhabdomyolysis and acute kidney injury; however, adrenal insufficiency as a result of snake bites has not been previously reported. We report a case of empty sella with transient adrenal insufficiency during hospitalization for a Mamushi bite. CASE PRESENTATION: An 84-year-old man was admitted to our hospital with a Mamushi bite on the right fifth finger. Serum sodium (Na) level remained in the normal range. On the ninth day of admission, he developed hyponatremia, with a serum Na level of 114 mEq/L and serum cortisol level of 4.0 µg/dL (reference value 4.5-21.1 µg/dL). His serum Na level was restored within the normal range after administration of corticosteroids with 3% NaCl solution. Both rapid adrenocorticotrophin and corticotropin-releasing hormone loading tests showed low cortisol response. Based on the results of the hormone loading tests, a diagnosis of pituitary adrenal insufficiency was made. Contrast-enhanced pituitary magnetic resonance imaging (MRI) showed primary empty sella. After discontinuation of corticosteroids, the hyponatremia did not recur, and the patient was discharged on the 24th day of hospitalization. After discharge, the patient visited an outpatient clinic, but hyponatremia recurrence was not observed. CONCLUSIONS: This is the first report of hyponatremia due to pituitary adrenal insufficiency during hospitalization for a Mamushi bite in a patient with empty sella. When hyponatremia occurs during hospitalization for a Mamushi bite, cortisol measurement, hormone loading test, and head MRI should be performed to search for pituitary lesions because of the possibility of adrenal insufficiency caused by snake venom.

Unusual and lesser-known rare causes of adult growth hormone deficiency.

Growth hormone is among the most common hormones to be deficient in pituitary insult. It can occur either in isolation or combined with other hormone deficiencies. Growth hormone deficiency in adults (AGHD) can be due to causes acquired in adulthood or have a childhood-onset etiology, but the former is about three times more common. Usual causes of AGHD include mass effects due to a pituitary tumour, and/or its treatment (surgery, medical therapy, or radiotherapy), or radiotherapy to the head and neck region for non-pituitary lesions. The unusual or lesser-known causes of AGHD, are usually due to non-tumoral etiology and range from vascular and infective to inflammatory and miscellaneous causes. These not only expand the spectrum of AGHD but may also contribute to increased morbidity, adverse metabolic consequences, and mortality due to the primary condition, if unrecognised. The review features these lesser-known and rare causes of AGHD and highlights their clinical and diagnostic implications.

Locally advanced endometrial cancer with multiple immune-related adverse events coinciding with the complete response to radiotherapy after immune checkpoint inhibitor therapy: A case report.

We report a case of a 70-year-old female patient with locally advanced endometrial cancer with primary empty sella who developed multiple immune-related adverse events (irAEs), including hypopituitarism coinciding with the complete response to radiotherapy after receiving immune checkpoint inhibitors. A computed tomography scan acquired after a traffic accident led to the discovery of endometrial cancer that had invaded the vulva and primary empty sella. Following adriamycin and cisplatin, pembrolizumab was administered for three cycles. No irAEs were observed during treatment, but the tumor was progressive. The patient underwent radiotherapy for the residual tumor. Four months after the last dose of pembrolizumab, hypopituitarism caused secondary adrenal insufficiency, primary hypothyroidism, and pseudogout at the end of radiotherapy. The tumor later achieved a complete response. In conclusion, radiotherapy after immune checkpoint inhibitor (ICI) therapy is expected to have an antitumor effect by stimulating tumor-specific immunity. However, proper management of irAEs is necessary. Patients with primary empty sella may be prone to pituitary insufficiency induced by ICIs.

Persistent postoperative hypotension caused by subclinical empty sella syndrome after a simple surgery: A case report.

BACKGROUND: Empty sella is an anatomical and radiological finding of the herniation of the subarachnoid space into the pituitary fossa leading to a flattened pituitary gland. Patients with empty sella may present with various symptoms, including headache due to intracranial hypertension and endocrine symptoms related to the specific pituitary hormones affected. Here, we report a female patient who developed persistent postoperative hypotension caused by subclinical empty sella syndrome after a simple surgery. CASE SUMMARY: A 47-year-old woman underwent vocal cord polypectomy under general anesthesia with endotracheal intubation. She denied any medical history, and her vital signs were normal before the surgery. Anesthesia and surgery were uneventful. However, she developed dizziness, headache and persistent hypotension in the ward. Thus, intravenous dopamine was started to maintain normal blood pressure, which improved her symptoms. However, she remained dependent on dopamine for over 24 h without any obvious anesthesia- and surgery-related complications. An endocrine etiology was then suspected, and further examination showed a high prolactin level, a low normal adrenocorticotropic hormone level and a low cortisol level. Magnetic resonance imaging of the brain revealed an empty sella. Therefore, she was diagnosed with empty sella syndrome and secondary adrenal insufficiency. Her symptoms disappeared one week later after daily glucocorticoid supplement. CONCLUSION: Endocrine etiologies such as pituitary and adrenal-related dysfunction should be considered in patients showing persistent postoperative hypotension when anesthesia- and surgery-related factors are excluded.
