Seroma de Morel-Lavallée: reporte de caso desde Manu, Perú, con diagnóstico y manejo en atención primaria

The Morel-Lavallée lesion is a post-traumatic fluid accumulation between fascial layers, commonly following an accident. Its diagnosis is based on clinical history and imaging tests, and treatment ranges from conservative measures to surgical interventions and sclerotherapy, depending on the age and size of the lesion. Effective management is crucial to prevent long-term complications. This report presents a 38-year-old male who suffered a knee contusion from falling off his parked motorcycle, developing a fluctuating mass and moderate pain. Initially treated with paracetamol, the lesion grew to 7 x 7 x 5.5 cm, requiring medical attention. It was confirmed by radiography and surgically drained, releasing serohematic fluid. The treatment included rest, limb elevation, and NSAIDs, showing significant improvement. This case underscores the importance of early diagnosis and proper management of Morel-Lavallée lesions to prevent long-term complications.
