Summary
This case highlights neurocryptococcosis, a severe fungal brain infection, presenting atypically in an immunocompetent individual. Early diagnosis and treatment are crucial for managing this opportunistic infection.
Area of Science:
- Infectious Diseases
- Neurology
- Immunology
Background:
- Neurocryptococcosis is a serious complication of Cryptococcus neoformans infection.
- It typically affects individuals with compromised immune systems.
Observation:
- A 53-year-old man with no prior medical history presented with severe headaches and vomiting.
- Initial treatment for suspected toxoplasmosis showed temporary improvement, but symptoms recurred.
Findings:
- Diagnosis confirmed neurocryptococcosis via biological tests, including flow cytometry.
- The patient exhibited CD4+ T-cell lymphopenia, linked to sarcoidosis-like granulomatosis.
- Treatment involved Amphotericin B and 5-Fluorocytosine.
Implications:
- This case demonstrates an unusual presentation of an opportunistic infection in a seemingly immunocompetent host.
- It underscores the importance of considering neurocryptococcosis even in patients without known immunosuppression.
- Highlights the diagnostic challenge and need for comprehensive workup in atypical presentations.

589
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

199
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

59
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

01:19Encephalitis l: Introduction
15
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

01:26Encephalitis ll: Pathophysiology
22
Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

01:26Brain Abscess l: Introduction
21
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...
