title: Clinical features and risk factors of cerebral infarction after mild head trauma under 18 months of age.
abstract: Mild head trauma can cause cerebral infarction in children younger than 18 months of age, yet the pathogenesis, clinical characteristics, and risk factors are not fully understood. Data of 16 cases between August 2008 and September 2011, including clinical manifestations and imaging and laboratory findings were collected and analyzed. All patients had the history of mild head trauma. The median age of the cohort was 13.5 months (range 6 months to 18 months). All children developed neurologic symptoms and signs within 72 hours after trauma, 62.5% (10/16) within 30 minutes. The first symptoms included hemiparesis (9/16), facial paresis (4/16), and convulsion (6/16). Overall, 93.75% (15/16) of the lesions were in the basal ganglia region. Two risk factors were identified, basal ganglia calcification in 10 and cytomegalovirus infection in eight. After conservative therapy, the neurologic deficits recovered to some extent. Cerebral infarction after mild head trauma in children younger than 18 months of age may take place, especially under the circumstances of basal ganglia calcification or cytomegalovirus infection.
