A case of Erdheim-Chester disease with intracerebral masses containing characteristic lipid-laden histiocytes is presented. These unusual lesions remained enhanced on magnetic resonance images obtained 8 days after injection of gadolinium diethylenetriaminepentaacetic acid (DTPA) dimeglumine. Chemical analysis of a biopsy specimen revealed a high concentration of gadolinium. Findings suggest that the Gd-DTPA complex or possibly a gadolinium-containing metabolite may be retained for extended periods in this unusual type of histiocytic lesion.
本文报告一例患有脑内肿块的厄尔海姆-切斯特病，肿块内含有特征性的富含脂质组织细胞。在注射钆喷酸葡胺（DTPA葡甲胺）8天后获得的磁共振图像上，这些异常病变持续强化。对活检标本的化学分析显示钆浓度很高。研究结果表明，钆-二乙三胺五乙酸（Gd-DTPA）复合物或可能含钆的代谢物可能会在这种特殊类型的组织细胞病变中长期留存。
