摘要
目的:对巨淋巴细胞增生症胸腹部CT表现及诊断结果进行分析。方法:运用随机抽样的方法选取自2000年1月至2014年9月收集的60例巨淋巴细胞增生症患者,运用西门子16排CT扫描,对所有患者进行CT平扫及增强扫描,对患者的胸腹部CT表现及诊断结果进行分析。结果:CT平扫,具有低或稍低密度15例,缺乏均匀的密度10例。通常情况下,肿块具有较为均匀的密度,胸腹部肿块均有显著强化,部分强化不均匀,腹膜后肿块部分有斑点状、片状高密度钙化存在于中央;缺乏均匀密度的肿块,增强没有显著强化存在于中央;直接征象和间接征象分别为肿瘤部位、大小、形态、边缘、强化方式和附近脏器受压情况。结论:巨淋巴细胞增生症具有较高的胸腹部误诊率,增强扫描病变呈现几乎同步于胸腹部主动脉的显著强化,延迟持续中度强化,在巨淋巴细胞增生症的诊断中具有极为重要的临床意义。
Objective： To analyze the chest and abdominal CT findings and diagnosis of giant lymph cell hyperplasia. Methods： 60 cases of giant lymph cell hyperplasia patients who were collected from January 2000 to September 2014 were selected by random sampling method, all patients were plain and enhanced by Siemens 16-slice CT scan, then the chest and abdominal CT findings and diagnosis of the patients were analyzed. Results： 15 cases of patients were with low or slightly low density, 10 cases were lack of uniform density. Under normal circumstances, the mass had a more uniform density, retroperitoneal tumor and part were lack of uniform density changes; retroperitoneal mass part of a sheet had high-density exists in the center, there was no significant enhancement to strengthen presence in the central, and thoracic and abdominal tumors were significantly strengthen, partly inhomogeneous enhancement; tumor location, size, shape and edge enhancement pattern were direct signs and pressure near the organ case were its indirect signs. Conclusion： Giant lymph cell hyperplasia has a higher rate of misdiagnosis of the chest and abdomen, and enhance scan lesions are significantly enhanced, the degree of enhancement in the thoracic and abdominal aorta are almost simultaneous, the delay continued moderate enhancement, it has very important clinical significance in the diagnosis of giant cell hyperplasia.
