Episode notes
Hematoma Expansion Dynamics
- Hematoma expansion, a major concern in intracranial hemorrhage (ICH), worsens the prognosis.
- This expansion, primarily occurring within six hours, compresses surrounding brain tissue, causing further damage.
Diagnosing CAA
- Consider cerebral amyloid angiopathy (CAA) in patients without hypertension who present with lobar bleeds.
- These bleeds often have a characteristic "finger-like" appearance on imaging.
Investigating Atypical ICH
- Use CT angiography to assess for secondary causes of ICH, like vascular malformations or aneurysms, when a patient's presentation is atypical for a hypertensive bleed.
- Factors like young age, female gender, lack of hypertension history, unusual bleed location, and visible vessel abnormalities on CT suggest possible secondary causes.
