Insights

Hemorrhagic stroke in children is rarely caused by cerebral paragonimiasis. This case highlights the importance of considering this parasitic infection in endemic areas when diagnosing childhood hemorrhagic strokes.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Cerebral paragonimiasis is an uncommon parasitic infection of the brain.
  • Hemorrhagic stroke is a rare presentation of cerebral paragonimiasis in pediatric patients.

Observation:

  • A 9-year-old boy presented with acute intracerebral hemorrhage, initially mimicking a typical stroke.
  • Initial investigations, including magnetic resonance angiography, did not reveal vascular abnormalities.
  • Recurrent symptoms and diagnostic workup, including MRI and serology, confirmed cerebral paragonimiasis.

Findings:

  • The patient's intracerebral hemorrhage was the primary clinical manifestation of acute cerebral paragonimiasis.
  • Diagnosis was established through advanced neuroimaging and enzyme-linked immunosorbent assay (ELISA).
  • Successful treatment with praziquantel led to gradual recovery.

Implications:

  • Cerebral paragonimiasis should be included in the differential diagnosis of hemorrhagic stroke in children, particularly in endemic regions.
  • Early diagnosis and treatment are crucial for favorable outcomes in pediatric cerebral paragonimiasis.
  • This case underscores the diverse neurological presentations of parasitic infections in children.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
Hemorrhagic Stroke ll: Pathophysiology01:29

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
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...
Stroke: Introduction and Types01:29

Stroke: Introduction and Types

A stroke is an acute neurological event caused by the sudden disruption of cerebral blood flow, leading to rapid loss of neuronal function. Neurons depend on continuous oxygen and glucose supply, so even brief interruptions can cause irreversible injury within minutes. Strokes are classified into ischemic and hemorrhagic types.Ischemic StrokeIschemic strokes are most common and occur due to arterial occlusion, depriving brain tissue of oxygen and nutrients. This leads to energy failure, ionic...
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...
