Childhood Basal Ganglia Stroke and its Association with Trivial Head Trauma

Abstract

This study explored the clinical profile, risk factors, neuroimaging and outcome of childhood basal ganglia stroke. Children (6 months-12 years) with basal ganglia stroke registered between 2007-2011 were retrospectively enrolled, while newly diagnosed cases over the 2-year study period were enrolled prospectively. Children with recent trivial head trauma were compared with those without it. Of the 35 children enrolled, trivial head trauma was seen in 74%. The non–trivial head trauma group (n = 9) comprised unidentified etiology (4), Moyamoya syndrome (2), varicella infection (1), homocysteinemia (1), and probable mitochondrial cytopathy (1). Median duration to complete recovery was significantly less in the trivial head trauma group (median = 12, range = 1-72 weeks vs median = 38, range = 20-48 weeks, P = .001). Moreover, these children had increased chances of complete recovery (85% [22/26] vs 44.5% [4/9], P = .029). Basal ganglia stroke can follow trivial head trauma and may have a more favorable outcome.
