Anatomic pattern of intracerebral hemorrhage expansion: relation to CT angiography spot sign and hematoma center.

ABSTRACT:

Background and purpose

We sought to identify baseline determinants of the anatomic pattern of hematoma expansion in patients with intracerebral hemorrhage and spot sign.

Methods

We coregistered baseline and follow-up CT scans from 15 intracerebral hemorrhage patients and measured growth at each surface node from baseline to follow-up hematoma. We analyzed the effects of proximity to the spot sign or hematoma center on distance of expansion, controlling for covariates.

Results

There was substantial node-to-node variation in the extent of expansion around each hematoma surface (mean coefficient of variation for expansion distance, 0.43; 95% confidence interval, 0.39-0.48), indicating nonuniform expansion. Closer proximity to the hematoma center was independently associa
