Madam LPS, a 69 years old lady complained of left eye blurring of vision since January 2017. It was associated with left orbital swelling with chemosis, eye redness, epiphora, several episodes of self-limiting epistaxis and bilateral ophthalmoplegia. Other neurological examinations and cerebellar systems were intact. Magnetic Resonance Imaging (MRI) Brain and Orbit were performed, depicting a sellar mass with suprasellar extension with blood investigations results showed panhypopituitarism. She underwent bilateral orbital decompression. Trans-nasal endoscopic biopsy showed suppurative granulomatous lesion, which cultured Candida Albicans and Candida Galbrata. She was started on antifungal and hormonal replacement therapy for panhypopituitarism. Unfortunately, she did not respond well to treatment as repeated MRI Brain on December 2018 showed increase in size of sellar mass causing obstructive hydrocephalus and increasing size of left orbital lesion. She was counselled for another debulking surgery with a ventriculoperitoneal (VP) shunt. HPE taken were reported as chronic inflammatory process in favour to fungal infection. Pituitary infections may mimic pituitary mass. Some may exhibit symptoms of panhypopituitarism as well. Thus, physical examination, MRI brain imaging as well as HPE of biopsy are important aids to achieve diagnosis. Optimal treatment of fungal pituitary abscess includes transsphenoidal surgery combined with antifungal therapy.

Symptoms of levothyroxine overdose may vary depending on age, metabolism, etc. There are no specific guidelines for treating levothyroxine poisoning. Here, we present the case of a 69-year-old man with a history of panhypopituitarism, hypertension, and end-stage renal disease who attempted suicide by ingesting 60 tablets of 150 µg levothyroxine (9 mg). Upon presentation to the emergency room, he was asymptomatic despite the free thyroxine level above the range of the assay. During the hospital stay, he developed sinus tachycardia, which was controlled with propranolol. Mild elevations in liver enzymes were also noted. He received stress-dose steroids; hemodialysis was performed a day earlier, and cholestyramine was administered. Thyroid hormone levels started to improve by day seven and finally normalized in 20 days, after which the home dose of levothyroxine was resumed. The human body has several mechanisms to compensate for levothyroxine toxicity, including the conversion of excess levothyroxine to inactive reverse triiodothyronine, increased binding to thyroid-binding globulin, and hepatic metabolism. This case shows that it is possible to have no symptoms even with an overdose of up to 9 mg a day of levothyroxine. Signs and symptoms of levothyroxine toxicity may not appear for several days after ingestion, and, therefore, close observation preferably on a telemetry floor is recommended until the thyroid hormone levels start to decrease. Effective treatment options include beta-blockers preferably propranolol, early gastric lavage, cholestyramine, and glucocorticoids. While hemodialysis has a limited role, antithyroid drugs and activated charcoal are ineffective.

A 59-year-old man was admitted to our hospital with hyponatremia. An endocrine examination indicated panhypopituitarism, and magnetic resonance imaging revealed a mass-like lesion in the pituitary gland. Sinus endoscopy revealed a fungal mass in the sphenoid sinus, and the patient was diagnosed with hypopituitarism due to aspergillosis of the central nervous system (CNS). The patient's hyponatremia resolved with hydrocortisone replacement. Although the right internal carotid artery was eventually occluded, antifungal medications were administered for the aspergillosis, and the patient's general condition improved. The patient's CNS lesions have remained under control since discharge. This is the first case to suggest that ACTH secretion may be relatively preserved in Aspergillus-induced hypopituitarism.

BACKGROUND
Childhood craniopharyngioma (cCP) has excellent survival, but quality of life may be severely hampered by hypothalamic dysfunction. We aimed to evaluate treatment and hypothalamic outcomes of a Dutch cCP cohort, and evaluate the effect of centralization of care.
METHODS
A retrospective cohort study was performed, including cCP patients diagnosed between 2004 and 2021. Treatment characteristics and hypothalamic outcomes were evaluated and compared before and since centralization of care in May 2018.
RESULTS
We included 87 cCP patients. Cyst drainage/fenestration was performed in 29.9%, limited resection in 27.6%, near-total resection in 16.1%, and gross total resection (GTR) in 25.4%. Radiotherapy was given in 46.0%. After a median follow-up of 6.5 years, hypothalamic obesity (HO) was present in 24.7% and panhypopituitarism with diabetes insipidus in 71.3%. Higher body mass index (BMI) SDS at diagnosis and Muller grade II at last magnetic resonance imaging of follow-up were associated with overweight/obesity. No association was found between extensiveness of resection and overweight/obesity at last follow-up. When comparing before and after centralization of care, rates of GTR remained similar, but BMI outcomes changed; mean ΔBMI SDS 1 year after diagnosis from 1.12 (SD 1.15) to 0.81 (SD 1.24), and HO after 1 year decreased from 33.3% to 12.0% (P = .067), and after 2 years from 28.6% to 6.7% (P = NS).
CONCLUSIONS
In our nationwide cohort, GTR was performed in a relatively low percentage of patients and extensiveness of resection was no longer associated with HO at follow-up. A trend toward improvement of BMI is observed since centralization of care, which needs further exploration.

UNLABELLED
Pituitary adenomas are the most common cause of hypopituitarism associated with pituitary enlargement, but other aetiologies have been emerging, namely immune checkpoint inhibitor-induced hypophysitis (ipilimumab, nivolumab and pembrolizumab). Secukinumab is a recently approved human monoclonal antibody used for the treatment of psoriasis, with no know reported cases of hypophysitis. We describe a challenging case of panhypopituitarism in a patient with a pituitary incidentaloma and a temporal relationship between secukinumab initiation and the manifestation of clinical features suggestive of hypopituitarism. In such intricate work-up, the differential diagnoses should be carefully considered, taking into account the therapeutic and prognostic implications.
LEARNING POINTS
Pituitary adenomas are the leading cause of hypopituitarism associated with pituitary enlargement, but clinicians should be aware of non-tumoural causes such as hypophysitis.Drug-induced hypophysitis has been described with immune checkpoint inhibitors used for diverse types of malignancies, but there is no evidence of an association between hypophysitis and the novel antipsoriatic agent, secukinumab.The differential diagnosis of hypopituitarism requires careful investigation so that management is appropriate and prognosis is improved.

Hypopituitarism is a rare disorder. Hypopituitarism can present as a deficiency of individual anterior pituitary hormones (e.g., adrenocorticotropic hormone, thyroid-stimulating hormone, luteinizing hormone, follicle-stimulating hormone, prolactin, growth hormone) or posterior pituitary hormones (e.g., oxytocin, vasopressin) or as the deficiency of all these pituitary hormones, also known as panhypopituitarism. Here, we discuss a 59-year-old man who presented with two episodes of unwitnessed syncope after an episode of vomiting. On admission, the patient was hypotensive to 88/54 mmHg, afebrile, and with a leukocyte count of 21.43 K/µL (reference range: 3.80 to 10.50 K/µL). CT scan of the head revealed a hyperdensity in the left intracranial internal carotid artery just proximal to the bifurcation, suggesting an artifact or presence of an embolus. Additional findings included a sellar mass with calcifications and suprasellar extensions. The patient was admitted for further workup of syncope. Other differential diagnoses included sepsis, stroke, cardiac arrhythmias, and pulmonary embolism. Sepsis, stroke, and cardiac workup were negative for significant findings. The patient remained persistently hypotensive despite aggressive intravenous hydration, raising suspicion for an underlying endocrine disorder. MRI of the brain was negative for stroke but again was significant for a sellar mass. Additional workup showed a deficiency of all the anterior pituitary hormones likely secondary to mass effect. The patient was diagnosed with panhypopituitarism due to pituitary macroadenoma.

INTRODUCTION
Hypopituitarism is a chronic disease characterized by partial or complete absence of secretion of one or more pituitary hormones. Delayed diagnosis can have serious consequences during the neonatal period and adulthood.
MATERIAL AND METHODS
A retrospective study was conducted on patients who had started treatment in the Children's Clinical University Hospital from 1 January 1995 to 31 December 2020. In total 243 patients were included; they were divided into 3 subgroups: isolated growth hormone deficiency, multiple pituitary hormone deficiency, and panhypopituitarism.
RESULTS
The prevalence of hypopituitarism in Latvia is about 45 cases per 100,000 live births. The average detection age of abnormal growth in Latvia is 8 years and 3 months. Most cases had isolated growth hormone deficiency, at 67.1% (n = 163), followed by cases of multiple pituitary hormone deficiency, at 26.3% (n = 64), and cases of panhypopituitarism, at 6.6% (n = 16). Abnormalities in MRI were found in 44.7% (n = 101) of patients. The most best therapeutic effect was achieved in the first year of treatment: with growth of an average of 9.3 cm (+0.1 SD) for isolated growth hormone deficiency, 9.0 cm (+0.6 SD) for multiple pituitary hormone deficiency, and 11.7 cm (+1SD) for patients with panhypopituitarism.
CONCLUSIONS
It is important to increase awareness and promote early diagnosis for hypopituitarism patients in Latvia and in Europe. More attention should be paid to education about growth restriction problems to parents, caregivers, and other specialists. The treatment should be adjusted individually with the focus not only on physical and mental health but also on safety and treatment costs.

Review
Non-functioning pituitary adenomas, recently alternatively termed pituitary neuroendocrine tumours (NFpitNETs), are mostly benign neoplasms that are not associated with a hormonal hypersecretory syndrome. The clinical spectrum of NFpitNETs varies from completely asymptomatic to the development of panhypopituitarism and manifestations attributed to mass effects on nearby structures. NFpitNETs follow generally an indolent course, but in 5-10% of cases they exhibit more aggressive behaviour, characterised by rapid growth, invasiveness and early recurrence. The initial size of the adenoma, the presence of symptoms and the histological subtype are related to the natural course of NFpitNETs. Active surveillance is usually the strategy of choice in the case of an asymptomatic NFpitNET, while surgical resection is recommended in case of visual and/or neurological abnormalities or rapid tumour growth. Based on previous and emerging data, approximately 50% of patients show tumour growth, while 20% of patients with NF-macroadenomas on active surveillance may require further intervention during a follow-up period of 7 years. Adjuvant radiotherapy is usually considered for large residual tumours or recurrent and/or aggressive adenomas, but there is evidence that medical therapy, especially with cabergoline, can occasionally be beneficial, whereas newer molecular agents are under investigation. Thus, while highly effective medical therapy is awaited, a move towards a more conservative approach seems appropriate, at least until we have better molecular markers of progressiveness.

Review
Craniopharyngiomas (CP) are suprasellar tumors that can grow into vital nearby structures and thus cause significant visual, endocrine, and hypothalamic dysfunction. Debate persists as to the optimal treatment strategy for these benign lesions, particularly with regards to the extent of surgical resection. The goals of tumor resection are to eliminate the compressive effect of the tumor on surrounding structures and minimize recurrence. It remains unclear whether a gross total resection (GTR) or subtotal resection (STR) with adjuvant therapy confers a better prognosis. Chemotherapy and radiation therapy (RT) have been explored as both neoadjuvant and adjuvant treatments to decrease tumor burden and prevent recurrence. The objective of this paper is to review the risks and benefits of GTR versus STR, specifically with regard to risk of recurrence and postoperative morbidity. Aggregated data suggest that STR monotherapy is associated with higher rates of recurrence relative to GTR (50.6% ± 22.1% vs 20.2% ± 13.5%), while STR combined with RT leads to recurrence rates similar to GTR. However, both GTR and RT are independently associated with higher rates of comorbidities including panhypopituitarism, diabetes insipidus, and visual deficits. The treatment strategy for CPs should ultimately be tailored to each patient's individual tumor characteristics, risk, symptoms, and therapeutic goals.

The presence of pregnancy in a brain-dead woman is a rare circumstance. We present a case of a 31-year-old woman who was 22 weeks pregnant at the time of diagnosis of brain death after intracranial and subarachnoid hemorrhage. After a multidisciplinary approach, the decision was made to continue somatic support to maintain the pregnancy until optimal fetus viability. Cesarean section was performed after 11 weeks (33 weeks gestational age) of brain-death diagnosis with a successful delivery of a live infant. Management of brain-death complications during pregnancy is described.
