ABSTRACT
BACKGROUND:
The multifocal hypointense cerebral lesions (MHCLs) on gradient echo (GE)-MRI and white matter changes on T2WI have been thought to be indicative of microangiopathy. The purpose of this study is to elucidate the relationship between MHCLs and white matter (WM) changes and the clinical significance of WM changes in stroke patients.METHODS:
We retrospectively reviewed MRI and clinical data of 115 patients with stroke (56 female and 59 male). Periventricular and deep white matter hyperintensity (PVHI and DWMHI) were measured by semiquantative rating scale proposed by Mantyla. The round, hypointense signal, less than 7 mm in diameter on GE-MRI were counted as MHCLs. The association between risk factors of stroke and MHCLs on GE-MRI and sum of the white matter change scores and total number of MHCLs were analyzed, respectively.RESULTS:
MHCLs on GE-MRI were significantly associated with old age (p<0.05) and hypertension (p<0.001) among risk factors of stroke. The distribution of MHCLs in subcortical area is associated with hypertension (p<0.05) and total number of MHCLs was significantly associated with sum of the white matter change scores (p<0.05).CONCLUSIONS:
MHCLs on GE-MRI were significantly associated with severity of WM changes. Severe WM change may be an indicator of advanced small artery disease of the brain with an increased risk factor for bleeding. This should be taken into consideration when treating patients with stroke.
