%X Prediction of intracerebral hematoma expansion (IHE) is of critical importance during intracerebral hemorrhage (ICH) management. Given its suggested positive connection with cerebral microvascular disease status, intracranial internal carotid artery wall calcifications (ICAC) on admission computed tomography (CT) studies may contribute to prediction of IHE.<BR>Presence, burden and type [as per Kockelkoren's score] of ICAC were defined in admission CT and CT-angiography of 201 ICH patients [mean age: 70 ± 13 years, 44 % female]. A Kockelkoren's score of <7 indicated intimal calcification [iICAC], while ≥7 indicated non-intimal [or medial] ones [mICAC]. IHE criteria were absolute volume increase of ≥12.5cc or ≥6cc, and relative increase ≥33 % or ≥26 %.<BR>ICAC was diagnosed in 79.6 % of ICH patients. ICAC status was not independent indicator of milder IHE (≥6cc and ≥26 % IHE, both in 27 %). Presence of contralateral mICAC was found to be an independent predictor for higher grade IHE (expβ = 3.44, 95 %CI: 1.47-8.04, for IHE ≥ 12.5cc, diagnosed in 14.4 %; and expβ = 2.67, 95 %CI: 1.29-5.55, for IHE ≥ 33 %, diagnosed in 24 %). Mortality (31 %) was higher in those with ipsilateral any type ICAC (36 % in mICAC, 38 % in iICAC, 17 % in no ICAC, p = 0.017), but this was not independent predictor in logistic regression. Similarly, medial ICAC in both ipsilateral (47 % vs. 31 %, p = 0.037) and contralateral (47 % vs. 30 %, p = 0.017) sides was associated with poorer prognosis (42 %) on univariate, but not multivariate analysis.<BR>Intracranial ICA calcification is highly prevalent in ICH. mICAC may be associated with risk of "high amount" acute hematoma expansion, hospital mortality and poor prognosis.
