Abstract

Morel-Lavallée lesion is a chronic, recurrent collection of serous fluid in the soft tissues and usually occurs following injury. The most common sites are thigh, hip and pelvic region. This presents as a local or diffuse swelling and may cause discomfort to the patient besides being a potential site for bacterial contamination. So, early diagnosis and timely management is crucial for an early and successful outcome. The investigation modality of choice for diagnosis of these lesions is MRI. Definitive management ranges from percutaneous aspiration with or without sclerotherapy to open debridement and irrigation. Although recurrences are common with conservative management, it can be minimised with judicious use of sclerotherapy.
