A review of 2000 consecutive magnetic resonance imaging (MRI) brain studies identified 18 (0.9%) patients with lesions that satisfied MRI criteria for cavernous haemangiomas. The clinical, computed tomography (CT) and MRI findings in 23 patients with probable cavernous haemangiomas were compared. Thirty-three lesions were identified with multiple lesions in five (22%) patients. In 19 (82%) patients the neurological presentation corresponded to a cavernous haemangioma. The presenting symptoms were: seizures in 11 patients (48%); progressive neurological symptoms and signs in four (17%); and acute symptoms and signs due to haemorrhage in four (17%). T2 weighted images suggested the diagnosis in all cases, with 24 (73%) lesions showing the typical appearance of an area of mixed signal intensity with a rim of low signal intensity. In the absence of acute haemorrhage, CT demonstrated well circumscribed, round or oval hyperdense lesions without significant mass effect and with normal surrounding brain tissue in the majority of cases. Although not diagnostic, these CT features are strongly suggestive of cavernous haemangiomas.
对连续2000例脑部磁共振成像（MRI）研究进行回顾，发现18例（0.9%）患者的病变符合海绵状血管瘤的MRI标准。比较了23例可能患有海绵状血管瘤患者的临床、计算机断层扫描（CT）和MRI表现。共发现33个病灶，其中5例（22%）患者有多个病灶。19例（82%）患者的神经学表现符合海绵状血管瘤。主要症状为：11例（48%）患者出现癫痫发作；4例（17%）患者出现进行性神经症状和体征；4例（17%）患者因出血出现急性症状和体征。所有病例的T2加权图像均提示诊断，24个（73%）病灶表现为典型的混合信号强度区域，周边有低信号强度环。在无急性出血的情况下，大多数病例的CT显示边界清晰的圆形或椭圆形高密度病灶，无明显占位效应，周围脑组织正常。这些CT特征虽不能确诊，但强烈提示海绵状血管瘤。
