Incidence of venous thromboembolism and bleeding in patients with malignant central nervous system neoplasm: Systematic review and meta-analysis.

Unlabelled: Central nervous system (CNS) malignant neoplasms may lead to venous thromboembolism (VTE) and bleeding, which result in rehospitalization, morbidity and mortality. We aimed to assess the incidence of VTE and bleeding in this population.

Methods: This systematic review and meta-analysis (PROSPERO CRD42023423949) were based on a standardized search of PubMed, Virtual Health Library and Cochrane (n = 1653) in July 2023.

Aseptic leptomeningitis induced by azathioprine in systemic lupus erythematosus: a rare manifestation.

Systemic lupus erythematosus (SLE) is an autoimmune systemic disease and these patients can have neurological involvement; however, aseptic leptomeningitis is considered to be a very rare feature, observed in 1.4-2.0% of patients.

Isolated Area Postrema Syndrome Preceding the Diagnosis of Giant Cell Arteritis: A Case Report.

Objective: We report a case of biopsy-proven giant cell arteritis after an initial presentation of area postrema syndrome.

Methods: A 65-year-old man was evaluated using MRI, temporal artery biopsy, and ultrasound.

Results: The patient presented with refractory nausea, vomiting, and hiccups that caused weight loss without any other neurologic or clinical symptoms.

Diffuse spinal cord metastasis after resection of SMARCB1 sinonasal carcinoma manifesting with a right foot drop-a case report.

Introduction: The sinonasal carcinoma are rare tumors of the head and neck. The undifferentiated sinonasal carcinoma subtypes are constantly being explored and new mutations, with different prognosis markers and biological behaviors are being described. The SMARCB1 negative sinonasal carcinoma subtypes have been recently described with few reports of leptomeningeal and spinal cord invasion.

An atypical case of neurotoxoplasmosis in immunocompetent patient.

Toxoplasmosis is an infection caused by , an intracellular protozoan that is often associated with immunocompromised patients and is rare in immunocompetent. A 60-year-old man was admitted with a history of 2 days of headache and right-sided weakness. There was no history of fever, surgeries, or any other comorbid illness.

Cerebral hemorrhage during the active phase of SARS-CoV-2 infection in a patient with amyloid angiopathy: case report.

The neurological changes associated with COVID-19 have been frequently described, especially in cases of greater severity, and are related to multifactorial causes, such as endothelial dysfunction, inflammatory mediator release (cytokine storm), endothelial dysfunction and hypoxemia. We report the case of a female patient, 88 years old, with cerebral hemorrhage associated with amyloid angiopathy in the context of SARS-CoV-2 infection.

Immune-mediated inflammatory polyneuropathy overlapping Charcot-Marie-Tooth 1B.

Charcot Marie Tooth (CMT) due to myelin protein zero (MPZ) mutations, may cause a wide variation of phenotypes, depending on the localization of the mutation within the gene. Among the most common phenotypes are: an infantile onset disease with extremely slow nerve conduction velocities (CMT1B) and an adult onset phenotype with nerve velocities in the axonal range (CMT2I). We reported a patient with CMT1B (MPZ p.

Tonic pupils: an unusual autonomic involvement in chronic inflammatory demyelinating polyneuropathy (CIDP).

Background: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a neuropathy which affects mainly large myelinated axons and has a typically mild autonomic dysfunction mainly from postganglionic nerve fiber involvement.

Case Report: We report here an acute onset CIDP initially diagnosed as Guillain-Barré syndrome (GBS), unresponsive to treatment with intravenous immunoglobulin (IVIg), which later responded to plasmapheresis and corticoids. The patient had a markedly distal demyelination, prominent cranial nerve involvement and, interestingly, bilateral fixed dilated pupils.

Web Vessels: Literature Review and Neurointerventional Management.

Objective: The aim of this study was to describe 27 patients with 32 web vessels (WVs) from our practice and provide a review of the literature regarding imaging diagnostics, clinical presentation, and treatment of WVs.

Methods: A MEDLINE search was performed using combinations of the following terms: "stroke in young adults," "web," "recurrent stroke," "diaphragm-like," "atypical fibromuscular hyperplasia," "atypical fibromuscular dysplasia," "septal fibromuscular dysplasia," "septa," "diaphragms," "pseudovalvular folds," and "carotid diaphragm." Our series was added in this review.
