Insights

A rare case of progressive multifocal leukoencephalopathy (PML) in a human immunodeficiency virus (HIV) patient resulted in a fatal outcome. Early diagnosis via brain biopsy is crucial for managing this opportunistic infection.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Oncology

Background:

  • Progressive multifocal leukoencephalopathy (PML) is a rare, demyelinating disease affecting the brain.
  • It is caused by the JC virus (JCV) and primarily occurs in individuals with compromised immune systems, such as those with human immunodeficiency virus (HIV) infection.

Observation:

  • A case of PML in an HIV-infected patient with a fatal outcome is presented.
  • The patient initially presented with hemiparesis and a non-enhancing lesion on computed tomography (CT) scan, misdiagnosed as an infarct.
  • Diagnosis was confirmed via brain biopsy four months after symptom onset.

Findings:

  • The delayed diagnosis, attributed to the initial misinterpretation of imaging findings, likely contributed to the patient's unfavorable outcome.
  • This case represents the first reported instance of PML in the region, highlighting a potential gap in regional disease surveillance and awareness.

Implications:

  • This case underscores the importance of considering PML in the differential diagnosis of neurological deficits in HIV-infected individuals, even with atypical initial presentations.
  • Timely diagnosis through methods like brain biopsy is critical for initiating appropriate management and potentially improving patient outcomes.
  • Increased awareness and diagnostic vigilance are necessary in regions where PML has not been previously reported.

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,...
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...

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Arboviral Encephalitis01:25

Arboviral Encephalitis

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...
