[Analysis of 15 cases of toxic encephalopathy caused by acute benzene poisoning].

In this paper, the MRI manifestations of 15 patients with benzene toxic encephalopathy were analyzed, and the lesion location, shape, scope and signal were observed. The clinical manifestations of 15 patients were mainly central nervous system damage, and the MRI manifestations were characteristic, with a wide range of lesions, and the shapes were "sunflower-like", "flame-like", "bracket-like" and "butterfly-like", and the MRI signal was sheet-like long T(1), long T(2), fluid attenuated inversion recovery (FLAIR) sequence and diffusion weighted imaging (DWI) high signal, apparent diffusion coeffecient (ADC) map low, equal or high signals. When the patient's diagnosis is unclear, MRI examination may provide clinical basis for diagnosis.本文分析15例苯中毒性脑病患者的磁共振成像（MRI）表现，观察其病变部位、形状、范围及信号等。15例患者临床表现以中枢神经受损为主，MRI表现具有特征性，病变范围广，形状呈"向日葵样""火焰状""括弧样""蝶翼样"，MRI信号为片状长T(1)、长T(2)，液体抑制反转恢复序列（FLAIR）和弥散加权成像（DWI）高信号，表观弥散系数（ADC）图低、等或高信号。在患者诊断不明确时，MRI检查可能为临床提供诊断依据。.
