Abstract
|
|
|
Purpose : To observe MR findings of vascular abnormality in Sturge-Weber syndrome and to determine the value of MRI in diagnosis.
Materials and Methods : Ten patients with Sturge-Weber syndrome (age : 3 months -32 years)were evaluated by MR imaging ; in six 3nd four cases, respectively, the results were correlated with those of CT and angiography We retrospertively analysed changes in the cortical vein and deep venous system. including the medullary and subependrmal vein. as well as enlargement of the choroid plexus, leptomeningeal enhancement. and changes in diploic space.
Results : In all cases except one. in which non-contrast enhanced study had been peformed varying degrees of leptomeningeal enhancement were seen. In nine cases the cortical vein became smaller ; enlargement of. the choroid plexus was seen in eight cases, change in the diploic space in seven (including three in which there was angiomatous involvement), and enlargement of the deep venous system in seven. In younger patients. collateral pathways were less developed and leptomeningeal angiomatous changes were more pronounced than in thase who were older.
Conclusion : MRI is a useful modality for the evaluation of vascular changes in Sturge-Weber syndrome. These changes vary according to a patient´s age and the duration of the disease.
