Abstract

Lipoma arborescens (LA) is defined as a villous lipomatous proliferation of the synovial membrane with diffuse substitution of the synovial tissue by mature fat cells. The injury is very rare, involving the knee joint (suprapatellar region) and is associated with degenerative joint disease. We describe the case of a male patient, suffering from ankylosing spondylitis with monoarthritis of the right knee and swelling in suprapatellar region important. The diagnosis of lipoma arborescens was confirmed from the MRI of the right knee.

摘要

树枝状脂肪瘤（LA）被定义为滑膜的绒毛状脂肪瘤样增生，成熟脂肪细胞弥漫性替代滑膜组织。这种损伤非常罕见，累及膝关节（髌上区域），并与退行性关节疾病相关。我们描述了一例男性患者，患有强直性脊柱炎，右膝单关节炎，髌上区域肿胀明显。通过右膝的磁共振成像（MRI）确诊为树枝状脂肪瘤。
