Presentation
Left side weakness noted by the parents.
Patient Data
Diffuse hypoattenuation of brain parenchyma in the whole right middle cerebral artery territory seen involving the right temporoparietal lobes, it has cortical and subcortical distribution and exerting mass effect in the form of effacement of the cortical gyri sulci, mild compression of the ipsilateral lateral ventricle.
Densely calcified thrombus at the MCA (M1).
Case Discussion
Stroke is relatively a rare disease in children, the risk factors differ from that in adults and include cardioembolic, hematologic, trauma, and infection, the symptoms may be subtle and the diagnosis of stroke in children is often delayed.
Computed Tomography should be used only when MRI not available and on unstable patients, It can adequately exclude hemorrhagic stroke or parenchymal abnormalities that produce a mass effect, and it may reveal a low-density lesion in arterial ischemic stroke and cerebral venous sinus thrombosis.
Cardio-embolism associated with about 30% of children with arterial ischemic stroke.
