To describe MR imaging characteristics and treatment options for prepatellar closed degloving injuries or Morel-Lavallée effusions. Imaging features are discussed that may aid in the distinguishing of this entity from "housemaid's knee" or prepatellar bursitis.
MR images of four young wrestlers were reviewed by two attending radiologists and one fellow, and correlative clinical data were collected using the electronic medical database.
MR images in all cases showed a unilocular, T2 hyperintense prepatellar collection extending beyond the normal boundaries of the prepatellar bursa. No necrotic fat or blood products were identified in the collections. Surgical pathology proving the absence of synovial tissue was available for one case, and differentiation of the collection from the adjacent bursa was confirmed visually by the surgeon in a second case.
Although prepatellar hemorrhagic bursitis and Morel-Lavallée effusions share many imaging features, making a specific diagnosis in most cases is not necessary, as treatment is often similar for both entities.
描述髌前闭合性脱套伤或莫雷尔-拉瓦利埃积液的磁共振成像（MR）特征及治疗选择。讨论有助于将该病变与“髌前滑囊炎”或髌前滑囊炎相鉴别的影像学特征。
两位主治放射科医生和一位住院医生对四名年轻摔跤运动员的MR图像进行了回顾，并使用电子医疗数据库收集了相关临床数据。
所有病例的MR图像均显示髌前单房性、T2高信号积液，超出髌前滑囊的正常边界。积液中未发现坏死脂肪或血液成分。有一例可获得手术病理证实无滑膜组织，另一例外科医生通过视觉确认了积液与相邻滑囊的区别。
尽管髌前出血性滑囊炎和莫雷尔-拉瓦利埃积液有许多影像学特征相同，但在大多数情况下无需进行明确诊断，因为这两种病变通常治疗方法相似。
