A Morel-Lavallée lesion (MLL) is a rare, closed traumatic soft-tissue degloving injury that is often misdiagnosed. The mechanism that results in this lesion involves a shearing force that separates the hypodermis from underlying fascia, thereby disrupting perforating vascular and lymphatic vessels and resulting in a hemolymphatic fluid collection prone to infection and pseudocyst formation. We describe a case of a 70-year-old male with an initially missed MLL despite CT imaging that was ultimately diagnosed on point-of-care ultrasound (POCUS) on a second emergency department visit. Although an MLL is often misdiagnosed on radiography and CT imaging, POCUS is an expeditious imaging modality that can facilitate diagnosis of an MLL by visualizing specific sonographic characteristics.
莫雷尔-拉瓦利损伤（MLL）是一种罕见的闭合性创伤性软组织脱套伤，常被误诊。导致这种损伤的机制涉及一种剪切力，该剪切力将皮下组织与深层筋膜分离，从而破坏穿支血管和淋巴管，导致易于感染和形成假性囊肿的血淋巴液积聚。我们描述了一例70岁男性病例，尽管进行了CT成像，但最初仍漏诊了MLL，最终在第二次急诊科就诊时通过床旁超声（POCUS）确诊。尽管MLL在X线摄影和CT成像上常被误诊，但POCUS是一种快速的成像方式，通过可视化特定的超声特征可以促进MLL的诊断。
