Beyond the Bruise: A Radiological Journey Into Morel-Lavallée Lesions Through Four Illustrative Cases

Morel-Lavallée lesions (MLLs) are rare closed degloving injuries resulting from significant trauma. These lesions occur when a high-impact force causes separation of the skin and subcutaneous tissue from the underlying fascia, leading to hemolymphatic collections. Despite their clinical significance, MLLs are frequently underdiagnosed, often leading to improper management and recurrence. This case series explores four illustrative cases of MLLs, highlighting the critical role of MRI in accurate diagnosis and staging. Detailed imaging features and optimal treatment options are discussed to guide clinicians in providing the best possible care. By raising awareness and providing a comprehensive understanding of these lesions, this series aims to enhance early detection and appropriate intervention, ultimately improving patient outcomes and reducing the mental distress associated with recurrent lesions.
