Sturge-Weber syndrome without facial nevus.

Overview

An 11-month-old patient with Sturge-Weber syndrome with the absence of facial angioma and normal mental development is presented. Noncontrast computed tomography revealed left parieto-occipital atrophy with heavy gyriform calcifications. Axial T(2)-weighed magnetic resonance imaging confirmed the presence of low-signal areas corresponding to the gyral calcifications evident on computed tomography. Contrast-enhanced T(1)-weighted axial and coronal images exhibited high signals in the left parieto-occipital cortical and subcortical areas, representing angiomatous malformations. The clinical appearance and pathologic features of the reported patient were compared with those of similar patients described in published reports.
