A rare, cytoplasmically inherited striatal degeneration associated with Leber's optic atrophy exhibited selective symmetric low-density lesions in the putamen on the CT scan in five patients. The CT findings, however, were asymmetric (one patient) and subtle in the early phases of the disease. Occasionally, caudate lesions were demonstrable. On MR imaging, the lesions had high signal intensity on T2-weighted images and low signal intensity on T1-weighted images. This group of patients was distinguished from patients with other causes of striatal degeneration by a lack of hemispheric, brainstem, or cerebellar atrophy.
一种与Leber视神经萎缩相关的罕见的细胞质遗传性纹状体变性，在5例患者的CT扫描中显示壳核有选择性对称性低密度病变。然而，CT表现（在1例患者中）不对称，且在疾病早期较轻微。偶尔可显示尾状核病变。在磁共振成像上，病变在T2加权图像上呈高信号强度，在T1加权图像上呈低信号强度。这组患者与其他原因导致的纹状体变性患者的区别在于没有半球、脑干或小脑萎缩。
