Characteristic distributions of intracerebral hemorrhage-associated diffusion-weighted lesions.

ABSTRACT:

Objectives

To determine whether small diffusion-weighted imaging (DWI) lesions occur beyond the acute posthemorrhage time window in patients with intracerebral hemorrhage (ICH) and to characterize their spatial distribution in patients with lobar and deep cerebral hemorrhages.

Methods

In this cross-sectional study, we retrospectively analyzed 458 MRI scans obtained in the acute (≤ 7 days after ICH) or nonacute (>14 days after ICH) phases from 392 subjects with strictly lobar (n = 276) and deep (n = 116) ICH (48.7% women; mean age 72.8 ± 11.7 years). DWI, apparent diffusion coefficient maps, fluid-attenuated inversion recovery, and T2* MRIs were reviewed for the presence and location of DWI lesions.

Results

We identified 103 DWI hyperintense lesions on scans from 62 su
