Abstract
We herein describe the case of a patient with chronic renal failure complicated by star fruit poisoning. T2-weighted and diffusion-weighted MR imaging showed hyperintense lesions at the thalami and right temporo-occipital cortex. Single voxel proton MR spectroscopy revealed elevation of lactate and (31)phosphorous MR spectroscopy revealed elevation of inorganic phosphate and decrease of phosphocreatine and nucleoside triphosphates. The imaging and metabolic changes indicated energy deprivation, with subsequent cortical necrosis proved at autopsy.
摘要
我们在此描述一例慢性肾衰竭并发杨桃中毒的患者。T2加权和扩散加权磁共振成像显示丘脑及右侧颞枕叶皮质有高信号病变。单体素质子磁共振波谱显示乳酸升高，（31）磷磁共振波谱显示无机磷酸盐升高，磷酸肌酸和三磷酸核苷降低。影像学和代谢变化提示能量缺乏，尸检证实随后发生了皮质坏死。
