We present a case of an 85-year-old woman with extensive metallosis of the left hip joint secondary to prosthetic polyethelene liner dislocation and wear. Radiographs demonstrated amorphous cloudy radiodensities surrounding the prosthesis, a feature we have called the "cloud sign." The presence of amorphous cloudy radiodensities as a radiographic sign of metallosis has not been previously described to our knowledge.
我们报告一例85岁女性患者，因人工聚乙烯内衬脱位和磨损继发左髋关节广泛金属沉着症。X线片显示假体周围有无定形云雾状放射密度影，我们将这一特征称为“云雾征”。据我们所知，此前尚无将无定形云雾状放射密度影作为金属沉着症的影像学征象的相关描述。
