Morel-Lavallee lesion (MLL) entity represents as a haemolymph mass as a result of closed degloving injury following focal trauma. The swelling can be mistaken as a tumor or simple hematoma formation, and it can be of concern as it gradually increases in size. It is important to diagnose the entity promptly as proper management can avoid skin necrosis and further complications. We present a 20-year-old female nursing student who fell down from a scooter and developed painful massive right thigh swelling over a 3-week course following trauma. She underwent plain radiography which was unremarkable. Ultrasound and magnetic resonance imaging revealed the diagnosis of MLL and she was treated accordingly.
