Abstract

Insights

Persistent neutrophilic meningitis, often caused by opportunistic pathogens, can be challenging to diagnose. This case highlights Nocardia cyriacigeorgica as a treatable cause, even in immunocompetent individuals.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Microbiology

Background:

  • Persistent neutrophilic meningitis is characterized by neutrophilic pleocytosis lasting over 7 days despite antibiotics.
  • Opportunistic pathogens are common causes, particularly in immunocompromised patients.

Observation:

  • A 47-year-old female presented with persistent neutrophilic meningitis following a basilar skull fracture.
  • The condition was unresponsive to broad-spectrum antibiotics, leading to multiple hospitalizations and relapses.
  • Nocardia cyriacigeorgica was eventually identified in the cerebrospinal fluid.

Findings:

  • Successful treatment involved a combination of Ceftriaxone and trimethoprim-sulfamethoxazole (TMP-SMX), followed by long-term TMP-SMX and doxycycline.
  • The patient achieved a complete recovery without any lasting neurological deficits.

Implications:

  • Delayed diagnosis of persistent neutrophilic meningitis can lead to significant morbidity.
  • Nocardia meningitis should be considered in persistent neutrophilic meningitis cases, even in immunocompetent patients.
  • Early and accurate microbiologic diagnosis is crucial for effective treatment and improved patient outcomes.

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

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,...

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
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,...
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...
