The Morel-Lavallée lesion is a closed, post-traumatic, soft tissue degloving injury. There is separation of the skin and subcutaneous tissue from the underlying fascia resulting in an effusion and creation of a perifascial space often containing lymph and necrotic fat.We present a case of a 70-year-old female that was referred to us with a painful right thigh after a fall from her bike. Ultrasound showed a persistent MLL and an ultrasound-guided injection with cortisone was injected the MLL, which resolved the patient's complaints.
