Brain MRI findings of carbon disulfide poisoning.

Cha JH, Kim SS, Han H, Kim RH, Yim SH, Kim MJ - Korean J Radiol (2002 Jul-Sep)

Bottom Line: T2-weighted images depicted white matter hyperintensity in 70 patients (76.9%) and lacunar infarcts in 27 (29.7%).In these patients, the prevalent findings at T2-weighted MR imaging of the brain were white matter hyperintensity and lacunar infarcts.Disturbance of the cardiovascular system by carbon disulfide might account for these results.

ABSTRACT

Objective: To evaluate the findings of brain MRI in patients with carbon disulfide poisoning.

Materials and methods: Ninety-one patients who had suffered carbon disulfide poisoning [male:female=87:4; age, 32-74 (mean 53.3) years] were included in this study. To determine the extent of white matter hyperintensity (Grade 0-V) and lacunar infarction, T2-weighted MR imaging of the brain was performed.

Results: T2-weighted images depicted white matter hyperintensity in 70 patients (76.9%) and lacunar infarcts in 27 (29.7%).

Conclusion: In these patients, the prevalent findings at T2-weighted MR imaging of the brain were white matter hyperintensity and lacunar infarcts. Disturbance of the cardiovascular system by carbon disulfide might account for these results.

Figure 1: A 34-year-old man exposed to carbon disulfide for nine years, but with no accompanying disease. T1- (A) and T2-weighted (B) axial images depict between 10 and 20 grade-II focal white matter lesions in the fontal lobe.

Mentions: The MRI findings were interpreted by a radiologist with no knowledge of the exposure level, being assessed for the presence of white matter hyperintensity and lacunar infarcts. T1- and T2-weighted images indicated that white matter lesions were isointense and hyperintense, respectively, and their location and grade were described. For grading, a modified six-point scale established by Horikoshi et al. (10) was used: grade 0: no lesions; grade I: less than 10 scattered focal lesions; grade II: 10 or more, but less than 20, scattered focal lesions; grade III: 20 or more scattered but non-confluent focal lesions; grade IV: partially confluent lesions; grade V: bilaterally diffuse confluent lesions (Figs. 1, 2). Lacunar infarcts were also counted, and their locations described. The grades of white matter hyperintensity and lacunar infarcts were compared between different age groups and between low and high exposure groups. Correlation analysis and the t test were used for statistical analysis.
