Early computed tomographic (CT) findings (scans obtained within 6 hours of the onset of stroke) were retrospectively analyzed in 25 patients with embolic cerebral infarction of the middle cerebral artery or internal carotid artery distribution, including the lentiform nucleus, diagnosed on the basis of findings at sequential CT. CT scans were analyzed for the following: (a) an obscured outline or partial disappearance of the lentiform nucleus, (b) a slight decrease in tissue density, or (c) effacement of the cortical sulci. One or more of these findings was recognized in 23 of 25 patients (92%). The first finding was noted most frequently, and it appeared earliest. Obscuration of the lentiform nucleus was thought to be an important early sign of cerebral infarction, including the lentiform nucleus.
对25例大脑中动脉或颈内动脉分布区（包括豆状核）发生栓塞性脑梗死的患者进行了回顾性分析，这些患者的早期计算机断层扫描（CT）结果（在卒中发作6小时内进行的扫描）是根据连续CT检查结果诊断得出的。对CT扫描进行了以下分析：（a）豆状核轮廓模糊或部分消失，（b）组织密度略有降低，或（c）脑沟消失。25例患者中有23例（92%）出现了上述一种或多种表现。第一种表现最为常见，且出现最早。豆状核模糊被认为是包括豆状核在内的脑梗死的重要早期征象。
