The computed tomographic (CT) findings in 34 patients in whom 45 lacunae were observed were reviewed. Twenty-four patients had a recent stroke-like clinical picture, whereas in ten patients, symptoms developed gradually. Three patients had no abnormal neurologic findings. Twenty-two patients had evidence of systemic arterial hypertension. A round or ovoid, sharply marginated, nonenhancing hypodense lesion that was smaller than 20 mm in diameter and that was seen on only two scan sections was considered characteristic of a cerebral lacuna. With the use of "high resolution" CT, the frequency of the diagnosis of cerebral lacunae by CT has markedly increased.
回顾了34例观察到45个腔隙的患者的计算机断层扫描（CT）结果。24例患者近期有类似中风的临床表现，而10例患者症状逐渐出现。3例患者无异常神经系统表现。22例患者有系统性动脉高血压证据。直径小于20mm且仅在两个扫描层面可见的圆形或椭圆形、边界清晰、无强化的低密度病变被认为是脑腔隙的特征性表现。随着“高分辨率”CT的应用，CT诊断脑腔隙的频率显著增加。
