Sturge-Weber syndrome imaging diagnosis by CT and MRI

Objective To discuss the pathologic change of sturge-weber syndrome and the manifestation features of CT and MRI to estimate its diagnostic value. Methods Retrospecting and analyzing the clinical and imaging materials of 15 Sturge-Weber syndrome. All patients underwent conventional spiral CT scans of which 2 patients with facial vascular nerves angioma in the trigeminal nerve distribution to find no abnormality so we used MRI enhancing check.Results Among 15 CT images, 13plain scans showed cortical calcification in affected side of which there were 4 with light calcification, 8 with medium calcification, 1 with heavy calcification and 2 with no calcification. In 2 MRI enhancing images,one showed the subcortical gyriform enhancement and the pia mater haemangioma and the other one showed choroids plexus enlargement of lateral venicles, dilated subependymal veins and deep vein vasvular. And all patients had cerebral atrophy in variouds degrees of which there were 6 troubled by unclear encephalon ray matter, 4 with choroids plexus enlargement of lateral ventricles and 6 with crania diploetic prominence.Conclusion The lobe subcortical calcification of"gyriform" is the characteristic manifestation of SturgeWeber syndrome and CT and MRI are the main checking means and it is valuable to use MRI enhancing scans to make a definite diagnosis of early Sturge-Weber syndrome.
