Morel-Lavallée lesions are traumatic abnormalities characterized by the accumulation of hemolymphatic fluid collection following disruption of subcutaneous fat tissue from the underlying deep fascia. Here, we present the case of a 63-year-old woman with a prepatellar Morel-Lavallée lesion, an unusual location for this pathology initially misdiagnosed as prepatellar bursitis. An MRI was performed allowing the correction of the diagnosis, highlighting the essential role of imaging in confirming the diagnosis and ruling out differentials such as prepatellar bursitis or neoplastic origins. In our case, conservative treatment with compression alone was employed, since surgery is reserved for chronic or complicated cases. Our experience underscores the utility of MRI in accurately delineating the anatomical extent and characteristics of prepatellar Morel-Lavallée effusion (PMLE). This imaging modality serves as a critical tool in guiding appropriate management strategies, ensuring timely and effective treatment for patients presenting with this lesion.
莫雷尔-拉瓦利损伤是一种创伤性异常，其特征是皮下脂肪组织与深层深筋膜分离后出现血淋巴液积聚。在此，我们报告一例63岁女性髌前莫雷尔-拉瓦利损伤病例，该病变的这一不寻常部位最初被误诊为髌前滑囊炎。进行了磁共振成像（MRI）检查，从而纠正了诊断，突出了影像学在确诊及排除诸如髌前滑囊炎或肿瘤起源等鉴别诊断方面的重要作用。在我们的病例中，仅采用了加压保守治疗，因为手术仅适用于慢性或复杂病例。我们的经验强调了MRI在准确描绘髌前莫雷尔-拉瓦利积液（PMLE）的解剖范围和特征方面的实用性。这种成像方式是指导适当管理策略的关键工具，可确保为出现该病变的患者提供及时有效的治疗。
