异想天开的近义词Findings
CT: CT shows a 5-mm focus of hyperattenuation with surrounding hypoattenuation within the superior right cerebellar hemisphere. Diffu sulcal and ventricular prominence, compatible with diffu cerebral volume loss. Scattered geographic regions of relative hypoattenuation within the bilateral periventricular white matter, compatible with small-vesl ischemic dia.
MRI: MRI shows numerous small, rounded areas of signal dropout, best appreciated on axial GRE, within the cerebellum, right paracentral pons, left posterior and ventral thalamus, and corona radiata.

CT：右小脑半球偏上部可见一直径约5mm高密度灶，周围环绕低密度影。脑沟、脑室广泛增宽，脑体积缩小。双侧侧脑室旁白质可见片状较低密度影，为脑小血管缺血性疾病表现。
MRI：GRE序列轴位图像示小脑、右侧脑桥近中心处、左侧丘脑后侧及腹侧、放射冠可见多发小类圆形低信号灶。

Discussion
Cavernous malformations
Cavernous malformations (also known as cavernomas) are benign vascular hamartomas that are comprid of sinusoids of endothelial-lined, immature blood vesls without intervening normal brain tissue. They demonstrate a wide range of behavior and may progress, regress, or enlarge. Cavernous malformations are the most common angiographically occult CNS vascular malformation, with a prevalence of approximately 0.5%. About 75% of cas are solitary (sporadic), with 10% to 30% of cas being multiple or familial. The average age of ont is age 40 to 60, but they can be en in children. They occur in equal frequency in men and women, and they are en in all ethnicities.
