Summary
Three patients with seizures and intracerebral hematomas experienced hematoma enlargement on repeat CT scans. The cause of these chronic expanding intracerebral hematomas remains unclear, despite extensive follow-up.
Area of Science:
- Neurology
- Radiology
Background:
- Intracerebral hematomas can present with various neurological symptoms.
- Normotensive patients with seizures and intracerebral hematomas are rare.
Observation:
- Three normotensive patients with seizures and intracerebral hematomas showed hematoma enlargement on serial CT scans.
- No vascular malformation or neoplasm was identified via angiography in two cases.
- Hematomas evolved from hyperdense to isodense, with slight enhancement in some cases.
Findings:
- Chronic expanding intracerebral hematomas can occur in normotensive patients presenting with seizures.
- The etiology of these expanding hematomas was not identified.
- Long-term follow-up showed no further neurological episodes.
Implications:
- This case series highlights a rare presentation of intracerebral hematomas.
- Further research is needed to understand the pathophysiology of chronic expanding intracerebral hematomas.
- Consideration of this entity is important for differential diagnosis in patients with unexplained hematoma expansion.
