| 目的 探讨海洛因白质脑病的CT特点及CT对本病的诊断价值。 方法 回顾分析10例海洛因引起的白质脑病的CT表现与临床资料,男6例,女4例,年龄13~38岁。有吸毒品海洛因史2~4年。其中5例做了增强CT扫描。 结果 海洛因白质脑病的CT表现为小脑齿状核、大脑后部脑白质、内囊后肢、胼胝体压部、大脑脚、中脑、桥脑对称的低密度影8例,以小脑损害为重,小脑中线两侧对称性边界的类圆形蝴蝶样病灶为特征。其中2例表现为双侧豆状核、内囊区对称性低密度灶。增强扫描无强化。 结论 海洛因海绵状白质脑病的CT表现有特征性,CT对本病诊断有重要价值。 |

| Objective To study heroin-induced leukoencephalopathy CT features and evaluate the value in CT diagnosis of the disease. Methods The author reviewed the CT and clinical data of 10 cases of heroin-induced leukoencephalopathy,6 male and 4 femal patients at the age of 13-38 years were presented,all of them had inhaled heroin for 2 to 4 years.The plain and contrast enhanced CT examinations were made in 5 cases. Results CT showed a symmetrical hypodensity of the cerebellar dentatum,posterior cerebral white matters,posterior limbs of internal capsule,splenium of corpus callosum,medial lemniscuses,midbrain,and pons in 8 patients,with the cerebellum heavily impaired. The most outstanding characteristics of the lesion were ring-like or butterfly-like in shape with clear margin in cerebellar hemispheres.Symmetrial hyperintense lesions of bilateral lenticular nucleus and internal capsule were found in 2 of the 10 patients.No contrast enhancement in CT was revealed. Conclusion The CT manifestation of the heroin-induced leukoencephalopathy is typical,which is of great value for the diagnosis in patients with heroin-induced lenkoencephalopathy. |
