Risk factors for computed tomography angiography spot sign in deep and lobar intracerebral hemorrhage are shared.

ABSTRACT:

Background and purpose

Patients with intracerebral hemorrhage (ICH) who present with a spot sign on computed tomography angiography are at increased risk of hematoma expansion and poor outcome. Because primary ICH is the acute manifestation of chronic cerebral small vessel disease, we investigated whether different clinical or imaging characteristics predict spot sign presence, using ICH location as a surrogate for arteriolosclerosis- and cerebral amyloid angiopathy-related ICH.

Methods

Patients with primary ICH and available computed tomography angiography at presentation were included. Predictors of spot sign were assessed using uni- and multivariable regression, stratified by ICH location.

Results

Seven hundred forty-one patients were eligible, 335 (45%) deep and 4
