| Abstract |
Objective
We assessed frequency and implication of cerebral artery calcification on computed tomography of the
brain in patients with acute cerebral infarction.
Methods
We retrospectively analysed 79 patients with acute cerebral infarction admitted in our institute from 2011
to 2013. Frequency and location of cerebral artery calcification, old infarction and white matter hyperintensity are
reviewed in computed tomography scan and magnetic resonance imagings.
Results
Cerebral artery calcification was very common findings in patients with acute cerebral infarction and was
observed in 61 patients (77.2%): internal carotid artery, 14 patients (17.7%), vertebrobasilar artery, 15 patients (19.0%)
and both arteries, 32 patients (40.5%). Cerebral artery calcifications were 41 (67.2%) in patients with lacunar infarction,
17 (27.9%) in patients with territory infarction, and 3 (4.9%) in patients with embolic infarction (p=0.084). Cerebral
artery calcifications were more frequent in elderly patients than younger patients (69.0 years vs 59.3 years, p=0.004).
Cerebral artery calcifications were more frequent in male patients than female patients (60.7% vs 39.0%, p=0.075)
and were more common in patients with hypertension (77.0% vs 50.0%, p=0.023). There were high incidence of
cerebral artery calcification in patients with old lacunar infarction (72.1% vs 27.9%, p=0.079) and white matter hyperintensity
in magnetic resonance imagings (75.4% vs 24.6%, p=0.001<).
Conclusion
Cerebral artery calcification is one of common radiological findings in patients with cerebral infarction,
but is not related to location of specific cerebral infarction. Instead, it seems to be associated with previous cerebrovascular
ischemic events such as old cerebral infarction or white matter hyperintensity. |
