FIG 1. Images from the case of a 9-year-old child with suspected left-sided Sturge-Weber syndrome.
A, Axial view contrast-enhanced T1-weighted image obtained at the level of the Monro foramina. Note the prominent but normal enhancement of vascular structures in the right hemisphere.
B, Axial view contrast-enhanced FLAIR image obtained at the level of the Monro foramina shows the improved visualization of leptomeningeal disease in the left temporal lobe. Note that enhancement of normal vascular structures in the right hemisphere is suppressed.
C, Axial view contrast-enhanced T1-weighted image obtained toward the vertex.
D, Axial view contrast-enhanced FLAIR image obtained toward the vertex shows considerably more enhancement in the left frontal lobe as compared with the T1-weighted image. More importantly, abnormal leptomeningeal enhancement is shown over the right frontal lobe, indicating bilateral disease. The presence of bilateral disease precluded surgical intervention.
