Summary
Basilar artery migraine can cause temporary brain imaging abnormalities that fully resolve over time. These transient changes are likely due to cerebral vasogenic edema, a type of brain swelling.
Area of Science:
- Neurology
- Radiology
- Neuroimaging
Background:
- Basilar artery migraine is a subtype of migraine with aura.
- Neuroimaging findings in migraine are typically transient and may mimic other conditions.
Observation:
- A 17-year-old male experienced two episodes of basilar artery migraine.
- Cranial computed tomography (CT) and magnetic resonance (MR) imaging revealed transient abnormalities after each migraine episode.
Findings:
- Repeat MR imaging six months after the final migraine episode demonstrated complete resolution of the observed abnormalities.
- The transient brain imaging abnormalities observed are hypothesized to be related to cerebral vasogenic edema.
Implications:
- This case highlights the transient nature of neuroimaging findings in basilar artery migraine.
- Understanding these transient changes is crucial for accurate diagnosis and to avoid misinterpretation as more severe neurological conditions.
- Cerebral vasogenic edema is a likely mechanism for these temporary imaging alterations in migraine patients.
