Abstract

Insights

This systematic review explored cerebral microbleeds (CMBs) and their histopathological features. While MRI shows CMBs, direct pathological validation is still needed, highlighting the need for further research.

Area of Science:

  • Neurology
  • Pathology
  • Radiology

Background:

  • Cerebral microbleeds (CMBs) are increasingly studied in cerebrovascular disease.
  • Histopathological correlation with neuroimaging findings of CMBs is an area of growing research interest.

Purpose of the Study:

  • To systematically review and characterize the pathological and radiological correlation of cerebral microbleeds (CMBs).

Main Methods:

  • A systematic literature search was performed.
  • Studies correlating histopathological characterization of CMBs with MRI findings were included.

Main Results:

  • Five studies with 18 patients were reviewed.
  • Hemosiderin deposition was the most frequent finding (49%).
  • Lipofibrohyalinosis was the most common associated vascular pathology; amyloid angiopathy was linked to dementia.

Conclusions:

  • Histopathological associations with MRI findings in CMBs have been observed.
  • Further research is warranted to validate these associations.

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...

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...

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...
