MRI versus CT for infantile seizures

Case contributed by Dr Joseph Scheller


Infant macrocephaly with an unprovoked seizure. MRI done 7 hours after the CT demonstrated no acute findings.

Patient Data

Age: 2 months
Gender: Female

Normal brain. Mild to moderately sized extra axial fluid collection.

Extra-axial fluid collection. Small bilateral posterior parietal subdural hematomas, Small bilateral intraventricular hemorrhage. Multiple foci of subarachnoid hemorrhage.

Case Discussion

Prevously healthy 2-month-old infant with macrocephaly had a seizure. Physical exam and routine blood work were unremarkable. A head CT demonstrated no acute findings. A skeletal survey and ophthalmologic exam were normal.  A head MR done 7 hours later confirmed subdural, subarachnoid and intraventricular hemorrhage thought to be due to cortical venous thrombosis. 

MRI scanning may not always be available for acutely ill infants, this case demonstrates the importance of obtaining urgent MRI studies if possible.
