Summary
Transient ischemic attacks (TIAs) can stem from various causes beyond atherosclerosis. This study highlights meningiomas and glioblastomas as critical, often overlooked, etiologies of TIA symptoms.
Area of Science:
- Neurology
- Vascular Neurology
- Neuro-oncology
Background:
- Transient ischemic attacks (TIAs) are commonly associated with cerebral atherosclerosis.
- Understanding diverse etiologies of TIAs is crucial for accurate diagnosis and management.
Observation:
- A 48-year-old woman experienced TIAs due to a meningioma compressing the internal carotid artery.
- A 67-year-old man presented with hemisyndrome, initially transient then persistent, suggestive of a glioblastoma with a steal phenomenon.
Findings:
- Meningiomas can cause TIAs through direct arterial narrowing.
- Glioblastomas may induce TIAs via a vascular steal syndrome within tumor vessels.
Implications:
- Broadens the differential diagnosis for TIAs beyond atherosclerotic disease.
- Emphasizes the need for advanced neuroimaging to detect non-atherosclerotic causes of TIA.
- Highlights the importance of considering neoplastic etiologies in TIA patients.
