Answer

CT scans may show calcifications in infants and even in neonates, with SWS; other findings include the following:

  • Brain atrophy

  • Ipsilateral choroid plexus enlargement

  • Abnormal draining veins

  • Breakdown of the blood-brain barrier with seizures

In a study of CT scans in 14 children with SWS, conducted by Terdjman et al, cortical calcifications were present in 12 patients (see the image below), localized atrophy had occurred in 10 patients, and enlargement of the choroid plexus and abnormal veins were found in 7 patients each. [61]
