Insights

A rare case of a 1-month-old infant with congenital human immunodeficiency virus (HIV) infection and herpes encephalitis developed a giant brain aneurysm. This highlights unusual cerebrovascular complications in infants with HIV.

Area of Science:

  • Pediatric Neurology
  • Infectious Diseases
  • Vascular Neurology

Background:

  • Neurological dysfunction is common in children with human immunodeficiency virus (HIV) infection.
  • Symptomatic cerebrovascular disease is infrequent in childhood HIV/AIDS.
  • Cerebral aneurysmal arteriopathy in pediatric AIDS typically has a long latency period.

Observation:

  • A 1-month-old infant with congenital HIV infection and herpes encephalitis presented with cardiorespiratory arrest and coma.
  • A giant saccular aneurysm of the left basilar artery was identified.
  • This represents a potentially the youngest reported case of aneurysmal arteriopathy in an infant with HIV and herpes encephalitis.

Findings:

  • Cerebral aneurysmal arteriopathy is an uncommon manifestation in newborns and infants.
  • The co-occurrence of congenital HIV, herpes encephalitis, and a giant basilar artery aneurysm in an infant is exceptionally rare.
  • The case prompts discussion on the roles of HIV and herpes simplex virus in the pathogenesis of such vascular lesions.

Implications:

  • This case expands the understanding of rare cerebrovascular complications in pediatric HIV infection.
  • It underscores the importance of considering unusual vascular pathologies in infants with combined viral infections.
  • Further research is needed to elucidate the specific mechanisms linking HIV and herpes simplex virus to aneurysmal formation in neonates.

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: 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...

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,...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
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,...
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...
