Morel-Lavallée Lesions: A Diagnostic and Clinical Dilemma

Morel-Lavallée lesions (MLL) occur following closed degloving injuries in trauma and appear as subcutaneous fluid collections. These lesions provide a diagnostic dilemma due to their resemblance to other subcutaneous lesions, including post-traumatic or post-procedural hematomas, and malignant entities such as soft tissue sarcomas. Magnetic resonance imaging (MRI) remains the diagnostic test of choice to diagnose MLL. Here we present a single case of MLL in a 40-year-old female who sustained an injury to her left thigh months earlier after falling through a pier as well as a review of literature on the diagnostic findings typically seen in this type of injury.
