INTRODUCTION
Sellar metastases (SM) are rare manifestations of malignancy. Breast and lung cancer are the most common primary tumors. Most cases are diagnosed in patients with advanced malignant disease; however, symptoms of pituitary involvement can precede the diagnosis of the primary tumor.
METHODS
Retrospective analysis of symptoms at presentation, hormonal, radiological and histological findings, management, and outcome of patients with SM from 2009 to 2020.
RESULTS
Eighteen patients'cases were included, 11 with histological confirmation. Median (m) age was 53 years (range 35-75), 53% male. Primary malignant tumors: 8 lungs, 6 breast, 1 follicular thyroid carcinoma, 1 Hodgkin lymphoma, and 2 clear cell renal carcinomas. The m time between the diagnosis of the primary neoplasm and the occurrence of the SM was 108 months (range: 11-180). In 8 patients the diagnosis of the primary neoplasm was made after the finding of the symptomatic sellar mass. Insipidus diabetes, adenohypophysis deficit, visual disorders, headache, and cranial nerve deficits were evident in 78, 77, 61, 39 and 39% of the cases, respectively. Fifteen patients harbored supra / parasellar masses, in three a lesion was limited to the pituitary gland, and stalk. Eleven out of 18 (61.1%) of the patients were operated on by the trans-sphenoidal approach, for diagnostic and / or decompressive purposes. Eighteen died, with a median survival time of 6 months (1-36).
DISCUSSION
In the presence of a pituitary lesion with diffuse gadolinium uptake, associated with insipidus diabetes and / or visual disorder SM should be suspected even in patients without a history of oncological disease.

Secondary spontaneous pneumothoraces occur in patients with known underlying lung disease. Patients with emphysema, bullae, and cystic lesions in the lungs are at high risk of developing pneumothorax. Cystic lung diseases like Langerhans cell histiocytosis (LCH) can present with complications like pneumothorax. Other common presenting features include maculopapular rashes and bone lesions. It can also be associated with endocrinopathies, most commonly central diabetes insipidus (CDI). We here present a case of a 22-year-old male who presented with pneumothorax, polyuria, and polydipsia. He was diagnosed with LCH on transbronchial lung biopsy, associated with CDI, and was treated with thoracoscopy-guided autologous blood patch for persistent air leak and subcutaneous cytarabine.

The Journal of Craniofacial Surgery Jun 2024To summarize the application experience of the pneumatic arm in transnasal sphenoidal pituitary adenoma resection under neuroendoscope.
OBJECTIVE
To summarize the application experience of the pneumatic arm in transnasal sphenoidal pituitary adenoma resection under neuroendoscope.
METHODS
A retrospective analysis was conducted on the clinical data of 52 patients with pituitary adenoma who underwent endoscopic transsphenoidal surgery with pneumatic arm fixation in the Neurosurgery Department of the First Affiliated Hospital of Anhui Medical University from July 2021 to March 2024. Among them, there were 5 cases of pituitary microadenoma, 35 cases of macroadenoma, and 12 cases of giant adenoma. Head CT and a full set of hormones were re-examined within 24 hours after surgery to evaluate the surgical effect. Follow-up was conducted by the outpatient department after surgery to assess the clinical symptoms, hormone level, and imaging of all patients.
RESULTS
Among 52 patients, gross total resection was achieved in 48 cases (92.3%), subtotal resection in 3 cases (5.8%), and partial resection in 1 case (1.9%). Preoperatively, 43 patients had diminished vision, with 40 showing improvement postoperatively, 1 worsening, and 2 having no significant improvement. Thirty-eight patients had headaches preoperatively, and all showed varying degrees of improvement postoperatively. Routine hormone examination within 24 hours after surgery showed that all 20 prolactinoma patients had restored normal hormone levels, 10 of 12 growth hormone-secreting adenoma patients normalized, and 4 of 6 cases of adrenocorticotropic hormone-secreting adenoma immediately relieved after surgery. Postoperative complications included intracranial hematoma in 1 case, cerebrospinal fluid leakage in 2 cases, transient diabetes insipidus in 6 cases, intracranial infection in 1 case, and no death cases. The median follow-up time of 52 patients was 18.6 months (range: 1-32 mo). During the follow-up period, the initial clinical symptoms of all patients improved to varying degrees, and they were able to work and live normally. At the last follow-up, 1 patient had recurrent tumor and 1 patient had progression.
CONCLUSION
Transnasal sphenoidal resection of pituitary adenoma using a pneumatic arm-fixed neuroendoscope allows the operator to perform the surgery with both hands, resulting in satisfactory overall tumor resection and fewer surgical complications. This technique has good clinical value for promotion.

PURPOSE
Copeptin efficiently predicts post-neurosurgical central diabetes insipidus (CDI) in patients with hypothalamic-pituitary lesions, but its role in characterizing changes in diuresis in individuals with acromegaly undergoing neurosurgery remains unexplored. Our study aimed to assess changes in postoperative fluid balance in acromegaly patients and correlate them with both copeptin and growth hormone (GH) levels.
METHODS
This was a secondary analysis of a prospective study involving 15 acromegaly patients undergoing endoscopic endonasal resection at our University Hospital. Fluid balance was assessed daily, and copeptin and GH levels were evaluated preoperatively (T0), and serially on the morning of the first (T2) and second (T3) postoperative day, with an additional measurement of copeptin one hour post-extubation (T1). Patients with pre-existing or post-neurosurgical CDI were excluded from the analysis.
RESULTS
Most patients (11/15) exhibited a negative fluid balance on the second postoperative day, with 4 developing polyuria. Postoperative GH levels did not differ significantly between polyuric and non-polyuric patients, but GH measured at T2 correlated significantly with negative total balance (r = -0.519, p = 0.048). Copeptin levels at T1 were significantly higher in those who developed polyuria (p = 0.013), and a copeptin value > 39.9 pmol/L at T1 showed excellent ability (Sensitivity 100%, Specificity 90.9%, p < 0.001) in predicting postoperative polyuria. Additionally, polyuric patients exhibited a higher T1 / T3 copeptin ratio (p = 0.013) and a negative fluid balance was associated with the remission of acromegaly at 12 months (p = 0.046).
CONCLUSION
The early assessment of copeptin, in addition to facilitating the rapid identification of individuals at increased risk of developing CDI, could also allow the recognition of subjects with a tendency towards non-pathological polyuria in the postoperative setting, at least in individuals affected by acromegaly.

PURPOSE
Malignant intracranial germ cell tumors (GCTs) are rare diseases in Western countries. They arise in midline structures and diagnosis is often delayed. We evaluated imaging characteristics and early tumor signs of suprasellar and bifocal GCT on MRI.
METHODS
Patients with the diagnosis of a germinoma or non-germinomatous GCT (NGGCT) who received non-contrast sagittal T1WI on MRI pre-therapy were included. Loss of the posterior pituitary bright spot (PPBS), the expansion and size of the tumor, and the expansion and infiltration of surrounding structures were evaluated. Group comparison for histologies and localizations was performed.
RESULTS
A total of 102 GCT patients (median age at diagnosis 12.3 years, range 4.4-33.8; 57 males; 67 in suprasellar localization) were enrolled in the study. In the suprasellar cohort, NGGCTs (n = 20) were noticeably larger than germinomas (n = 47; p < .001). Each tumor showed involvement of the posterior lobe or pituitary stalk. A PPBS loss (total n = 98) was observed for each localization and entity in more than 90% and was related to diabetes insipidus. Osseous infiltration was observed exclusively in suprasellar GCT (significantly more frequent in NGGCT; p = .004). Time between the first MRI and therapy start was significantly longer in the suprasellar cohort (p = .005), with an even greater delay in germinoma compared to NGGCT (p = .002). The longest interval to treatment had circumscribed suprasellar germinomas (median 312 days).
CONCLUSION
A loss of the PPBS is a hint of tumor origin revealing small tumors in the neurohypophysis. Using this sign in children with diabetes insipidus avoids a delay in diagnosis.

An 11-year-old male child who presented with increased frequency of urination, thirst and feeling of incomplete void was initially diagnosed with diabetes mellitus (DM) based on elevated blood sugar. Polyuria and polydipsia were confirmed even after normalisation of blood sugar. A standardised water deprivation test showed presence of central diabetes insipidus (DI) and patient was started on desmopressin. Presence of DM and DI led to suspicion of DIDMOAD/Wolfram syndrome and ophthalmic examination confirmed bilateral optic atrophy. Despite treatment for DM and DI the urinary complaints persisted, and ultrasound showed persistent bilateral hydronephroureterosis. Bladder workup including voiding cystourethrography (VCUG) and urodynamic study reported thickened trabeculated bladder wall along with overactivity, poor compliance and high bladder pressure. Bladder dysfunction has been documented to be associated with Wolfram syndrome and often may lead to chronic kidney disease which can be prevented by early diagnosis and appropriate management. The case highlights the need for comprehensive evaluation of children with urinary symptoms.

This article aims to identify patient- and surgery-related factors that could predict the development of postoperative central diabetes insipidus (DI). This is a retrospective case-control study conducted at a single-institution tertiary referral center. Patients undergoing endoscopic endonasal skull base surgery for pituitary adenoma between November 2018 and April 2023 were recruited. The main outcome measures collected include age, gender, comorbidities, tumor type, postoperative DI, intraoperative and postoperative cerebrospinal fluid (CSF) leak, flow of CSF leak, number of layers required for repair, the use of nasal packing, and hospital length of stay. A total of 20 patients developed DI postoperatively. Patients' demographic and comorbidity profile did not correlate with DI development. The encounter of an intraoperative CSF leak was correlated with postop DI (chi-square (1) = 18.35, < 0.001) with a relative risk (RR) of 2.7 (confidence interval [CI] = 1.37-5.28). The use of nasal packs was also correlated with postop DI (chi-square (1) = 10.17, = 0.001) with a RR of 1.8 (CI = 1.15-2.87). Defects requiring a two or more layers for reconstruction also correlated with postop DI compared to single layer repairs (chi-square (1) = 12.15, < 0.001) irrelevant of the materials used. Development of DI postop correlated with an increased hospital length of stay ( (64) = -3.35, = 0.001). The physician should be careful when evaluating patients with pituitary adenomas in the postoperative period, particularly those with intraoperative CSF leak, nasal packing, and those who underwent multilayer reconstruction of the surgical defect.

In this report we present a case of a 14-year-old girl with type 1 diabetes mellitus (T1DM) who experienced glycemic instability and multiple hormonal deficits, including diabetes insipidus, central hypothyroidism, and central adrenal insufficiency. Brain and sellar magnetic resonance imaging revealed a mass in the suprasellar region, which was confirmed to be a pituitary abscess through transsphenoidal biopsy. T1DM is a chronic systemic disease that can lead to suboptimal glycemic control and increased susceptibility to infections. Pituitary abscess is a rare and serious infection that can manifest with nonspecific signs and symptoms, as well as pituitary hormonal deficiencies. Currently, after a 6-year follow-up the pituitary hormone deficiencies have resolved apart from persistent partial diabetes insipidus. Through a review of the current literature, we discuss the clinical characteristics of pituitary abscess, the challenges in diagnosing it, and speculate on the potential clinical and pathophysiological relationship between this uncommon infection and T1DM in our patient.

Neurosurgical Review Jun 2024The study intends to clarify the optimal endoscopic endonasal surgical strategy for symptomatic Rathke's cleft cysts (RCCs).
PURPOSE
The study intends to clarify the optimal endoscopic endonasal surgical strategy for symptomatic Rathke's cleft cysts (RCCs).
METHODS
We retrospectively analyzed patients with RCCs that underwent EEA surgery. The strategy for surgical and reconstruction method selection was presented. Patients were split into groups of fenestration open or closed. Pre- and postoperative symptoms, imaging, ophthalmologic, and endocrinologic exams were reviewed. The incidence of complications and the recurrence rates were determined.
RESULTS
The 75 individuals were all received primary operations. The fenestration closed group contained 32 cases, while the fenestration open group contained 43 cases. The median follow-up period was 39 months. The three primary complaints were headache (n = 51, 68.00%), vision impairment (n = 45, 60.00%), and pituitary dysfunction (n = 16, 21.33%). Of the 51 patients with preoperative headaches, 48 (94.12%) reported improvement in their symptoms following surgery. Twenty-three out of 45 patients (51.11%) experienced an improvement in visual impairment. Pituitary dysfunction was found improved in 14 out of 16 individuals (87.50%). There was no discernible difference in the rate of symptom alleviation between both groups. There were three patients (3/75, 4.00%) had cyst reaccumulation. One of them (1/75, 1.33%), which needed reoperation, was healed using pterional approach. In term of complications, cerebral infections occurred in two patients (2/75, 2.67%). Both of them recovered after antibiotic treatment. No postoperative cerebrospinal fluid rhinorrhea occurred. One patient (1/75, 1.33%) in the open group experienced epistaxis. There was no persistent hypopituitarism or diabetes insipidus (DI). Analysis of headache related factors showed that the presence of wax like nodules was related to it.
CONCLUSION
RCC was successfully treated with endoscopic endonasal surgery with few problems when the fenestration was kept as open as feasible. Preoperative identification of T2WI hypointense nodules may be a potential reference factor for surgical indication.

The post-surgical outcome for Hypothalamic Hamartoma (HH) related epilepsy in terms of seizure freedom (SF) has been extensively studied, while cognitive and psychiatric outcome has been less frequently reported and defined. This is a systematic review of English language papers, analyzing the post-surgical outcome in series of patients with HH-related epilepsy (≥5 patients, at least 6 months follow-up), published within January 2002-December 2022. SF was measured using Engel scale/equivalent scales. We looked at the outcome related to different surgical techniques, and HH types according to Delalande classification. We evaluated the neuropsychological and neuropsychiatric status after surgery, and the occurrence of post-surgical complications. Forty-six articles reporting 1318 patients were included, of which ten pediatric series. SF was reported in 686/1222 patients (56,1%). Delalande classification was reported in 663 patients from 24 studies, of which 70 were type I HH (10%), 320 were type II HH (48%), 189 were type III HH (29%) and 84 were type IV HH (13%). The outcome in term of SF was reported in 243 out of 663 patients. SF was reported in 12 of 24 type I HH (50%), 80 of 132 type II HH (60,6%), 32 of 59 type III HH (54,2%) and 12 of 28 type IV HH (42,9%). SF was reached in 129/262 (49,2%) after microsurgery, 102/199 (51,3%) after endoscopic surgery, 46/114 (40,6%) after gamma knife surgery, 245/353 (69,4%) after radiofrequency thermocoagulation, and 107/152 (70,4%) after MRI-guided laser interstitial thermal therapy. Hyperphagia/weight gain were the most reported surgical complications. Others were electrolyte alterations, diabetes insipidus, hypotiroidism, transient hyperthermia/poikilothermia. The highest percentage of memory deficits was reported after microsurgery, while hemiparesis and cranial nerves palsy were reported after microsurgery or endoscopic surgery. Thirty studies reported developmental delay/intellectual disability in 424/819 (51,7%) patients. 248/346 patients obtained a global improvement (72%), 70/346 were stable (20%), 28/346 got worse (8%). 22 studies reported psychiatric disorders in 257/465 patients (55,3%). 78/98 patients improved (80%), 13/98 remained stable (13%), 7/98 got worse (7%). Most of the patients had non-structured cognitive/psychiatric assessments. Based on the available data, the surgical management in patients with HH related epilepsy should be individualized, aiming to reach not only the best epilepsy result, but also the optimal cognitive and psychiatric outcome.
