Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

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 infections,...
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Cryptococcal Meningitis01:27

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

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...
Encephalitis ll: Pathophysiology01:26

Encephalitis ll: Pathophysiology

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...

Summary

Necrotizing neurosarcoid, a rare central nervous system (CNS) condition, is presented in three new cases. This rare form of neurosarcoidosis may be more common than previously thought and warrants consideration in CNS diagnoses.

Area of Science:

  • Neurology
  • Immunology
  • Pathology

Background:

  • Neurosarcoidosis affects 5% of sarcoidosis patients.
  • Necrotizing neurosarcoidosis of the CNS is exceptionally rare, with only three prior reports.
  • This study presents three new cases of necrotizing neurosarcoidosis with diverse CNS involvement.

Observation:

  • Patients presented with diverse neurological deficits including unresponsiveness, hearing loss, and limb weakness/numbness.
  • CNS involvement varied, encompassing leptomeningeal disease, cerebellopontine angle masses, and spinal cord lesions.
  • Biopsies confirmed necrotizing granulomatous inflammation.

Findings:

  • Serum Angiotensin-Converting Enzyme (ACE) levels were normal in tested patients.
  • Diagnosis was confirmed via surgical biopsy revealing necrotizing granulomatous inflammation.
  • Treatment involved systemic corticosteroids, with one patient receiving an additional immunosuppressive agent.

Implications:

  • Necrotizing neurosarcoidosis may be underdiagnosed.
  • Consider necrotizing neurosarcoidosis in CNS disease differentials, even without systemic sarcoidosis signs.
  • Further research is needed to understand the prevalence and optimal management of this rare condition.
