A Morel-Lavallée lesion is a post-traumatic soft tissue degloving injury which presents as a haemolymphatic mass or collection. Morel-Lavallée lesions are the result of direct trauma or shearing forces abruptly separating skin and subcutaneous tissue from underlying fascia causing disruption of perforating vessels and nerves, creating a potential space that may fill with blood, lymph and debris forming a collection. ⋯ Early diagnosis and management is essential to prevent complications. We present this pictorial review to highlight the imaging characteristics of Morel-Lavallée lesions across imaging modalities to improve recognition, early diagnosis and management.
