An unusual computed tomography finding, the "target sign," is demonstrated in a patient with a corpus callosum tumor mass extending to the right lateral ventricle. The central low attenuation of the "target" is produced by the isolated part of the dilated lateral ventricle surrounded by tumor tissue, the dense area of the "target." The diagnosis of the tumor of the corpus callosum and the explanation of the "target sign" was made by polytome pneumoencephalography.
一名患有胼胝体肿瘤且肿块延伸至右侧脑室的患者显示出一种不寻常的计算机断层扫描表现，即“靶征”。“靶”的中央低密度区是由被肿瘤组织包围的扩张侧脑室的孤立部分产生的，即“靶”的致密区。胼胝体肿瘤的诊断及“靶征”的解释是通过多层面气脑造影做出的。
