In scanogram, evidence of gyriform calcification is detected in central part of skull from anterior to posterior.
In non-contrast brain CT scan, unilateral right-sided atrophy of cerebral hemisphere with gyriform cortico-subcortical (tram-track) calcification are seen. Increased subarachnoid space on right side and mild thickening of overlying calvarium is seen. No ventricular dilation or obvious choroid plexus enlargement is noted.
Also, cortical calcification at the right cerebellar hemisphere is visible without sign of atrophy.
These findings are consistent with Sturge-Weber syndrome.
