Abstract：ObjectiveTo explore the clinical features, diagnosis and treatment of seroma after Morel-Lavallée injury. MethodsThe clinical data of a patient with seroma after Morel-Lavallée injury treated in the Department of Traumatology, Daping Hospital on August 19, 2024 were analyzed retrospectively, and the literature was reviewed. ResultsThe patient, a 48-year-old male, was injured on July 22, 2024 by a heavy object crushing his chest and abdomen. On August 13, 2024, the patient found swelling in the left inguinal area and gradually extended to the left thigh. Pelvic magnetic resonance imaging and CT examination in the outside hospital showed multiple injuries and effusion, suggesting lymphatic leakage, with rhabdomyolysis to be excreted. Lymphography showed lymphatic effusion from the left upper thigh to the left inguinal region, with minor gas and lymphatic leakage observed around the soft tissue, considering lymphatic vessels injury in the left inguinal region with reflux obstruction and leakage. Following the necessary examinations upon admission, the abdominal drainage tube and the left inner thigh drainage tube were retained, and the left thigh was bandaged with pressure. After 7 days, the drainage tube was removed and bandaged under continuous pressure. There was no effusion in ultrasonic examination, and the patient's symptoms were obviously improved without surgical treatment. ConclusionsMorel-Lavallée seroma is often misdiagnosed or diagnosed late. Therefore, a thorough understanding of the diagnosis and treatment of Morel-Lavallée seroma is crucial.
