HEMIPLEGIA CAUSED BY STURGE-WEBER ANGIOMA TOSIS WITHOUT CEREBRAL INFARCTION IN TERM PREGNANCY

During the third quarter of her pregnancy, a young woman with Sturge-W eber angiomatosis hud a severe right hemiplegia with hemianopia and ap hasia, followed 48 hours later by focal seizures. Neuroimaging did not show any cerebral lesion but contrast magnetic resonance imaging reve aled a left hemispheric pial angiomatosis. The patient recovered progr essively from the third day after a ceasarean. The hemianopia disappea red within 15 days. the hemiplegia within one month and the aphasia gr eatly improved within 3 months. Ten weeks after the clinical onset, we performed a positron emission tomography study. A decrease from 15 to 40% of the cerebral radioactivity was observed after injection of wat er ((H2O)-O-15) or fluorodesoxyglucose ((18)FDG) in the left temporooc cipital area adjacent to the meningeal angiomatosis. A chronic and foc al olighemia, already reported in Sturge-Weber angiomatosis, might par ticipate in the occurrence of this cortical metabolic depression.
