Summary
The number of intracerebral microbleeds (MBs) detected on initial MRI scans may predict the risk of recurrent intracerebral hemorrhage (ICH). This finding is crucial for understanding ICH recurrence risk in patients with MBs.
Area of Science:
- Neuroimaging
- Neurology
- Vascular Medicine
Background:
- Intracerebral microbleeds (MBs) are common in patients with intracerebral hemorrhage (ICH).
- The predictive value of MBs for recurrent ICH remains unclear.
Purpose of the Study:
- To investigate whether MBs are predictors of recurrent ICH.
- To assess the relationship between baseline MBs and recurrent ICH events.
Main Methods:
- 63 primary ICH patients with gradient-echo T2*-weighted MR imaging (GRE) were analyzed.
- Baseline and follow-up GRE evaluated ICHs and MBs.
- Recurrent ICHs were assessed in relation to clinical, laboratory, and MB data.
Main Results:
- 43 (68.3%) patients had baseline MBs.
- Seven patients developed recurrent ICHs; six had initial MBs.
- The number of baseline MBs significantly predicted recurrent ICH (p < 0.0001).
Conclusions:
- Recurrent ICHs and new MBs are common during long-term follow-up.
- Baseline MB count on GRE is a potential predictor for ICH recurrence.

01:17Hemorrhagic 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...
01:29Hemorrhagic 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...
