OBJECTIVE To explore the perihematomal perfusion typing and spot sign on computed tomography angiography (CTA) source images in order to assist in individualizing therapeutic decisions for @entity1 with @entity1779 by possibly forecasting perihematomal @entity63 and @entity1410 enlargement. METHODS We examined 58 @entity1 with spontaneous @entity1779 by computed tomography perfusion and CTA within 6 hours after symptom onset. @entity1410 volumes were determined from non-contrast CT images and compared between first and second CT images. The perfusion of @entity1410 region and perihematoma region was evaluated for presence or absence of the perihematomal penumbra. Three kinds of perihematoma perfusion typing were defined according to the perfusion of @entity1410 region and perihematoma region. CTA source images was reviewed to make sure presence or absence of the spot sign. RESULTS Finally, 53 @entity1 (34 males, 19 females) were enrolled in our study according to exclusion criteria. Finally, 21 @entity1 were classified into the normal group, 23 @entity1 were classified into the mild group, and 9 @entity1 were classified into the severe group. There were significant differences in @entity1410 size between the presence and absence of the perihematomal penumbra group (P<0.05). Thirteen (24.5%) @entity1 presented with spot sign. @entity1410 expansion occurred in 15 (28.3%) @entity1 on follow-up. In which 12 @entity1 were with spot sign. Sensitivity, specificity, positive predictive value, and negative predictive value for expansion were 80.0%, 97.4%, 92.3%, and 92.5%, respectively. CONCLUSION: In acute @entity1779 @entity1 , the perihematoma perfusion typing and CTA spot sign provide more radiological information that might assist in individualizing therapeutic decisions for @entity1 by possibly forecasting perihematomal @entity63 and @entity1410 enlargement.
