RESUMEN
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.

A teoria da inibiçäo da piridoxamina pelo CS2 e a conseqüência interferência no metabolismo do triptofano, tem sido estudada por alguns autores e se apresenta como muito promissora para a elucidaçäo de um dos mecanismos de açäo tóxica desse solvente industrial. A funçäo da Vitamina B6 no organismo humano, principalmente sobre o metabolismo do triptofano e a excreçäo do seu principal metabilito, o ácido xanturenico, é estudada no presente trabalho, correlacioando-se a exposiçäo ocupacional ao sulfeto de carbono
