English: CT scan of a Morel-Lavallee lesion.
Article description: A 57-year-old man with no underlying disease was hit by a train in a factory. He experienced an iliac wing fracture with a friction burn on the inguinal region (Figure 5). Retrospectively, a subcutaneous hematoma was found around the left iliac wing (Figure 6). As there was no obvious fluctuation, MLL was not initially recognized. Subcutaneous hematoma was revealed around the left greater trochanter when performing open reduction and internal fixation for the iliac fracture on the 6th day after the trauma. We irrigated the interior of the lesion with pulsed lavage and placed a drainage tube through small incisions, similar to Case  1. Because the lesion was infected at 3 days after surgery, we left the lesion exposed (Figure 7). The infection was soon brought under control, and skin grafting was performed at 9 weeks after the trauma. The wound was completely healed at 4 months after the trauma (Figure 8).
