Pleomorphic xanthoastrocytoma (PXA) is a brain neoplasm included in the astrocytic group, exceptionally manifesting with meningeal dissemination. We described a 27-year-old patient presented with acute bilateral visual loss and papilledema with normal brain computed tomography scan, initially mimicking idiopathic intracranial hypertension (IIH). Brain and spinal cord magnetic resonance imaging (MRI) study revealed a subtle area of hyperintensity of the gyri surrounding the left central sulcus, and contrast enhancement of the thoracic leptomeninges. Brain biopsy of the parietal lesion revealed nonanaplastic PXA. Treatment with temozolomide was given. Yearly control MRI demonstrated new brain lesions and marked progression of leptomeningeal spinal enhancement. In spite of this, the patient has remained stable with no new symptoms. Nonanaplastic PXA may present with widespread meningeal dissemination with acute visual loss and papilledema mimicking IIH, and no clinical progression at 3 years.

Toxoplasmal meningoencephalitis is a sporadic condition that is often misdiagnosed antemortem, frequently resulting in euthanasia especially in resource-limited settings. Here we report a case of a 7-week-old female domestic shorthair cat from an animal shelter who presented in a compromised condition and continued to display clinical signs consistent with a "failure to thrive" kitten. Weight loss and decreased activity were observed, and later on, neurological dysfunction became apparent.

Background: Atypical teratoid/rhabdoid tumours (ATRTs) are malignant central nervous system tumours, typically presenting in the posterior fossa of very young children. Prognosis remains poor despite current therapy, while tumorigenesis implicates both genomic and epigenetic dysregulation. Primary diffuse leptomeningeal (PDL) ATRT, characterised by the absence of an intraparenchymal mass lesion, is seldom reported but appears associated with a dismal outcome.

Coccidioidal meningitis is a rare yet life-threatening complication of disseminated infection, primarily affecting immunocompromised individuals. and are dimorphic fungi endemic to the southwestern United States, where exposure to inhaled spores can lead to a range of clinical manifestations, including pulmonary and central nervous system (CNS) involvement. This report describes the case of a 27-year-old correctional officer with advanced human immunodeficiency virus (HIV) infection who presented with chronic headaches, altered mental status, and significant weight loss following his relocation from Arizona to Louisiana.

Background: The global resurgence of disseminated tuberculosis (TB) after the coronavirus disease 2019 pandemic highlights the necessity of understanding host risk factors, especially in adults without human immunodeficiency virus.
Methods: We reviewed TB cases admitted to Shanghai Public Health Clinical Center from 2017 to 2022. We analyzed baseline characteristics and outcomes.

Introduction: is a formidable pathogen that poses a significant threat to immunocompromised and might cause rare atypical forms of the disease especially complicated with coinfection.
Case: We present a case of a patient with meningoencephalitis, endocarditis, sepsis, and osteomyelitis, highlighting the complexities of managing disseminated polymicrobial infection. A 64-year-old female with multiple myeloma treated with chemotherapy presented with fever, altered mental status, nausea, and diarrhea to the emergency department.
