Intracranial hypertension due to central venous stenosis (CVS) is an under-recognized but potentially morbid complication of central venous catheters that can have a benign course if recognized and treated early. Here we report a case of a 23-year-old woman requiring hemodialysis via right subclavian catheter who presented with an intracranial hypertension syndrome and sudden visual loss secondary to right innominate vein thrombosis that improved after angioplasty treatment. This case illustrates how CVS can alter the pressure gradient between the subarachnoid space and the cerebral venous sinuses by increasing venous pressure, affecting cerebrospinal fluid drainage. Since CVS is a common finding in patients receiving hemodialysis, intracranial hypertension due to central venous stenosis is a differential diagnosis to consider in patients of this type who present with intracranial hypertension syndrome.

Introduction
Sellar and parasellar tumors are frequent lesions in neurosurgical practice, highlighting pituitary adenomas, craniopharyngiomas, and sellar tubercle meningiomas. The clinical manifestations are similar, however; There are imaging aspects that differentiate them.
Objective
Show imaging aspects of tumors in the sellar and parasellar region that guide their histopathological diagnosis.
Method
A descriptive, longitudinal and prospective study was carried out that included 200 patients from the Hermanos Ameijeiras Hospital, of which 120 had a histopathological diagnosis of pituitary adenoma, 50 of craniopharyngioma and 30 of sellar tubercle meningioma. The variations in the displacement of the point of the anterior communicating arterial complex and in the premammillary angle were analyzed by means of a cerebral nuclear magnetic resonance study. For data analysis, absolute and relative frequencies were used as summary measures.
Results
A cephalic displacement of the anterior communicating arterial complex was evident in the craniopharyngiomas, of 10–11.9 mm (84.0 %); in pituitary macroadenomas, 12−14 mm (78.3%); and in sellar tubercle meningioma, ≥14 (86.6 %) mm. When evaluating the premammillary angle, pituitary adenomas were identified between 85º and 95º (73.3 %); in craniopharyngiomas, <85º (90.0 %); and in meningiomas of the sellar tubercle, between 85 and 95º (86.6 %).
Conclusions
The present study allows us to identify imaging characteristics in sellar and parasellar tumors that guide with high certainty the histopathological diagnosis and thus establish a more effective treatment.

The olfactory neuroblastoma is a rare malignant neoplasm derived from the olfactory neuroepithelium. It can metastasize to cervical lymph node chains and distant organs through hematogenous or lymphatic routes. Two clinical cases are presented: the first, a 56-year-old man with no pathological history, exhibited symptoms evolving over 2 months, characterized by persistent rhinorrhea with frequent epistaxis, ipsilateral proptosis, left hemicranial pain, anosmia, and dysgeusia. Radiological images showed involvement of paranasal sinuses, left orbital cavity, and intracranial region. The second case involved a 46-year-old male with progressive symptoms over more than 1 year, including nasal obstruction, rhinorrhea, self-limited epistaxis, anosmia, weight loss in the last 3 months, and subjective decrease in visual acuity. A protruding mass in the left nasal fossa was observed without intracranial involvement. Both cases were pathologically and immunohistochemically consistent with olfactory neuroblastoma, Hyams grade 2.

Introduction and objectives
Halo braces treat upper cervical spine fractures and serve as the most rigid form of external immobilization. Recently, halo braces have lost favor due to known complications and advances in surgical stabilization. This study aims to determine the contemporary incidence for use of halo braces and identify risk factors associated with mortality in trauma patients undergoing halo brace for cervical spine fractures.
Materials and methods
The 2017–2019 Trauma Quality Improvement Program Database was queried for patients ≥18 years-old with a cervical spine fracture undergoing halo brace. Patients sustaining penetrating trauma and severe torso injuries (abbreviated injury scale >3 for the abdomen or thorax) were excluded. Bivariate and multivariable logistic regression analyses were performed.
Results
From 144,434 patients with a cervical spine fracture, 272 (0.2%) underwent halo brace and 14 (5%) of these died. Those who died were older (73.5 vs. 53 years-old, p = 0.011) and had higher rates of hypertension (78.6% vs 33.1%, p < 0.001) and chronic kidney disease (14.3% vs. 1.2%, p < 0.001). Glasgow Coma Scale ≤8 (46.2% vs. 8.2%, p < 0.001) and cervical spinal cord injury (71.4% vs. 21.3%, p < 0.001) were more common in patients who died. In addition, those who died more often sustained respiratory complications (7.1% vs. 0.4%, p = 0.004) and sepsis (7.1% vs. 0.4%, p = 0.004). On multivariable logistic regression analysis, only Glasgow Coma Scale ≤8 (OR 19.77, 3.04–128.45, p = 0.002) was associated with increased mortality.
Conclusions
Only 5% of cervical spine fracture patients undergoing halo brace died. Respiratory complications and sepsis were more common in those who died. On multivariable analysis only Glasgow Coma Scale ≤8 remained an independent associated risk factor for mortality.

Moyamoya disease (MMD) and moyamoya syndrome (MMS) are considered rare in Indonesia, without any proper epidemiological data backing this claim. Hence, this case series aims to assess all MMD and MMS cases from the perspective of a multicentre private hospital in Indonesia.
Methods
This is a descriptive analysis using data from the picture archiving and communication system (PACS) from January 2019 to December 2023. The inclusion criteria included all patients who fulfilled the radiological criteria for MMD and/or MMS, while patients who only underwent brain non-contrast computed tomography (CT) scans were excluded.
Results
There are 58,905 unique MRI scans from 2019 to 2023. The cohort comprises 8 females and 2 males, with a median age of 37 (7–65) years old. Three cases are probable MMD. with six MMD cases and one MMS case. Therefore, the prevalence rate for the four years is approximately 11.9 cases per 100,000 scans. Out of the confirmed Moya-Moya cases, the majority (4/7) are ischemic subtypes, followed by epileptic (electroencephalography shows slowing brain waves) and TIA in one case each. The most common presenting symptom is weakness in the extremity (N = 7), followed by headache (N = 5). Four patients underwent operative procedures, with three of them being superior temporal artery to middle cerebral artery (STA-MCA) bypass procedures and one of them being encephalo-duro-myo-arterio-pericraniosynangiosis (EDMAPS).
Conclusion
The paucity of confirmed cases either points towards the low prevalence of MMD and MMS in Indonesia or the underdiagnosis of these cases.

During lymphoma’s natural history of disease, 5–10% of cases may develop Central Nervous affectation. We present the case of a 57-years-old man with less than 24 h of onset symptoms of paraparesis, lower limb hypoesthesia and sphincter dysfunction who was operated due to dorsal tumor with epidural component which caused severe cord compression. Pathological analysis concluded atypical T-cell lymphoblastic lymphoma, a rare subtype of lymphoma which accounts 1%−2% of all Non-Hodgkin Lymphomas. Our case was particularly aggressive and atypical due to its origin in paraspinal soft tissue. Despite specific treatment, the patient presented an early epidural relapse, frequent in this lymphoma subtype.

Introduction
The global incidence of spinal pathology is increasing due to the progressive aging of the population and increased life expectancy. Vertebral fixation with transpedicular screws is the most commonly used technique in unstable or potentially unstable pathologies. There are different implantation methods, the most recently developed being implantation guided by robotic navigation.
Materials and methods
We describe the technical aspects and the different workflows available with the ExcelsiusGPS® robotic navigation system (GlobusMedical, Inc, Audubon, PA, USA), as well as the results of the first 40 patients operated on at the Hospital Universitario la Paz between July 2023 and February 2024.
Results
A total of 250 screws were implanted at the thoracic and lumbar levels. 12 patients underwent minimally invasive surgery (MIS) (30%) and 28 patients underwent open surgery (70%). The median number of screws implanted per patient was 6.00 (4.00–6.00). The intraoperative malpositioning rate was 2.5% (1 case). The median duration of surgery was 143.00 minutes (113.00–165.50). The median hospital stay was 4.00 days (3.00–5.50). The median intraoperative radiation delivered was 899 mGy/cm2 (523.25–1595.00). The median blood loss was 150.00 ml (100.00–300.00) and the blood transfusion rate was 0%.
Discussion
Compared to conventional techniques, Robotic spine surgery increases accuracy to 96–100% and reduces the radiation dose received by the patient and surgical team. In addition, it allows the implantation of larger screws, which has been associated with increased biomechanical strength and reduced risk of loosening. Initially, it may involve an increase in total surgical time, but this is reduced once the learning curve is reached, around 40 cases.
Conclusions
ExcelsiusGPS® is the most recent robot model on the market and different studies have demonstrated its effectiveness in different techniques and indications. Unlike other robotic systems used exclusively in dorsolumbar spine pathology, it can be used in the pathology of the entire spinal axis (from C1 to the sacrum) and brain pathology (deep electrode implantation, brain biopsy, SEEG, among others).

Trigeminal neuralgia is a well-characterized disorder of high prevalence among the current population. It may be caused, among many other causes, by a tumor which contacts with the trigeminal nerve, often of large volume. We present the case of a middle-aged woman without any remarkable medical background who suffered a trigeminal neuralgia caused by a subcentimeter tumor which appeared to be a meningioma. Some small tumors like this one may be symptomatic whereas larger ones will not. We discuss the pathogenesis and characterization of the trigeminal neuralgia in such cases proposing some mechanisms that could be involved in the development of a secondary neuralgia.
