Intracerebral amyloidoma is the least common form of amyloid deposition in the brain. CT and MR imaging features in a case of pathologically proved cerebral amyloidoma are presented, and the available literature is reviewed. Typical imaging features of this entity include solitary or multiple supratentorial white matter masses that are hyperattenuated on nonenhanced CT. They have little or no mass effect on surrounding structures, extend medially up to the lateral ventricle wall, and have fine, irregular, enhancing margins.
脑内淀粉样瘤是脑内淀粉样沉积最罕见的形式。本文报道了一例经病理证实的脑淀粉样瘤的CT和MR成像特征,并对现有文献进行了综述。该病变的典型影像学特征包括幕上孤立或多发的白质肿块,在非增强CT上呈高密度。它们对周围结构几乎没有或没有占位效应,向内延伸至侧脑室壁,边缘有细小、不规则的强化。
