The goal of this study was to follow over time the MR imaging features of cortical laminar necrosis.
Six patients with cortical laminar necrosis were included. There were two women and four men aged 54-84 years, with a mean age of 68 years. In four patients, cortical laminar necrosis was caused by ischemic stroke, one case occurred after a cardiac arrest and the last patient had a meningoencephalitis. The time delay from insult to the first MR study varied between one week and 3 months.
The MRI showed hyperintense lesions in the cerebral cortex on T1W and T2W images. The high intensity signal was still observed a few months after the insult. Cortical laminar necrosis lesions did not demonstrate hemorrhage on CT and MRI studies.
MRI allowed detection of cortical laminar necrosis and could differentiate it from hemorrhage.
本研究的目的是长期跟踪皮质层状坏死的磁共振成像（MR）特征。
纳入6例皮质层状坏死患者。其中2例女性，4例男性，年龄54 - 84岁，平均年龄68岁。4例患者的皮质层状坏死由缺血性卒中引起，1例发生在心脏骤停后，最后1例患者患有脑膜脑炎。从损伤到首次MR检查的时间间隔在1周和3个月之间。
MRI显示在T1加权（T1W）和T2加权（T2W）图像上大脑皮质有高信号病变。损伤后几个月仍可观察到高强度信号。CT和MRI检查显示皮质层状坏死病变无出血表现。
MRI能够检测皮质层状坏死，并可将其与出血相鉴别。
