To discuss the imaging features of AIDS patients complicated with bone infarction.MethodFour AIDS patients complicated with moderate and advanced bone infarction were enrolled and their imaging data was analyzed retrospectively.ResultsFour patients were all involved with bilateral femoral inferior segment and proximal tibia. Irregular low-density shadow could be seen in the X-ray film, and there were trip or point flaky calcified shadows in the medullary cavity. CT examination showed that bone trabecular structure disappeared, and irregular calcification was visible with strip hardened edge around cancellous bone. MR imaging showed slightly hyperintense or isointense on T2WI images, and hypointense or isointense on T1WI images, and some double-hypointense also could be visible. Between the normal bone marrow and the edge, abnormally hyperintense, winding long T2 hyperintense and T1 hypointense could be visible via STIR sequences.ConclusionX-ray, CT and MRI were all favorable for diagnosis of AIDS patients complicated with moderate and advanced bone infarction, among which, by contrast, MRI seemed to be the most efficient imaging examination.
