Abstract

Morel-Lavallée is a rare lesion caused by post-traumatic soft tissue injury. It usually occurs around the greater trochanter, and it occurs very rarely in the lumbar region. It is often difficult to be diagnosed in the emergency room. Delayed diagnosis may result in the need for open surgery. The authors report a patient with extensive multiple Morel-Lavallée lesions in the thoracolumbar, buttock, and thigh after trauma and provide a literature review.

  Fig. 1 Sagittal T2-weighted fat-suppressed image of the thoracolumbar spine (A) shows a large fluid collection within the subcutaneous tissues, from the T10 level to the S1 level. Coronal T2-weighted fat-suppressed image of the left thigh (B) and axial image of the right hip (C) show a fluid collection between the fascia and the subcutaneous layer.
