Insights

Serial magnetic resonance imaging (MRI) revealed evolving lesions in chronic cryptococcus meningo-encephalitis. Treatment with antifungal therapy led to decreased lesion enhancement and intensity, aiding differential diagnosis.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Radiology

Background:

  • Chronic cryptococcal meningo-encephalitis is a serious central nervous system infection.
  • Magnetic resonance imaging (MRI) is crucial for diagnosing and monitoring CNS infections.
  • Understanding the serial imaging changes in cryptococcal meningo-encephalitis is important for patient management.

Observation:

  • Serial MRI demonstrated evolving focal lesions in the brain over time.
  • Initial T2-weighted hyperintensity in the left thalamus progressed to rim enhancement.
  • A separate lesion in the right pons showed T2-hyperintensity and gadolinium enhancement.

Findings:

  • Antifungal therapy (amphotericin B and 5-flucytosine) resulted in decreased lesion enhancement and signal intensity.
  • The observed MRI changes reflect the inflammatory and treatment response in cryptococcal meningo-encephalitis.
  • Cryptococcoma can present as ring-enhancing lesions, necessitating differentiation from other pathologies.

Implications:

  • This case highlights the characteristic serial MRI findings in chronic cryptococcal meningo-encephalitis.
  • Recognizing these imaging patterns aids in the early diagnosis and appropriate treatment of this opportunistic infection.
  • Distinguishing cryptococcoma from other ring-enhancing lesions is critical for effective patient care.

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,...
Viral Meningitis01:18

Viral Meningitis

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...
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...
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,...
Bacterial Meningitis I: Introduction01:22

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...
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...
