PERIVENTRICULAR HEMOSIDERIN DEPOSITION IN PATIENTS WITH CONGENITAL HEMIPLEGIA

Two patients with congenital hemiplegia without obvious prenatal, peri natal or neonatal difficulties showed linear low signal intensity lesi ons along the wall of the dilated lateral ventricles without any paren chymal lesions on T-2- and proton density weighted MRI. Haemosiderin d eposition secondary to intra-uterine subependymal haemorrhage with int raventricular haemorrhage was considered most likely from the signal i ntensity, distribution and clinical histories. MRI, which is the only means of detecting haemosiderin deposition, could be beneficial for ev aluating the pathogenetic cause of congenital hemiplegia.
