Abstract
Although the association between basal ganglia (BG) stroke and mild traumatic brain
injury (TBI) is well recognized, its association with lenticulostriate vasculopathy
has only recently been described. We present the case of a 6-month-old female infant
without personal or familiar relevant records who presented with left-sided hemiparesis
and without altered consciousness after a mild TBI. An emergency computed tomography
(CT) scan of the brain revealed bilateral linear calcifications along the course of
the lenticulostriate arteries. Brain magnetic resonance imaging (MRI) revealed an
ischemic lesion in the right BG and damage to the posterior limb of the right internal
capsule. A few months after the ischemic event, the patient was asymptomatic. Given
the clinical, radiological, and evolutionary characteristics of this group of patients,
the term mineralizing angiopathy is proposed to define a specific clinical-imaging syndrome in infants who suffer
a BG stroke after a mild TBI and present with the calcification of the lenticulostriate
arteries.
