[Table/Fig-5]:

Same patient as in [Table/Fig-4]. MRI lumbar spine sagittal a) T1, b) T2 and; c) and d) axial T1 & T2 images demonstrate a lenticular shaped collection between the thoracolumbar fascia and overlying subcutaneous fat and superficial fascia consistent with Morel-Lavallée. There is mild T1 hyperintensity relative to muscles with an internal area of T1 and T2 hypointensity (yellow arrowheads) representing retracted clot. There is hypointense capsule (blue arrow) and internal septations. Ultrasound images of the same region e) and f) demonstrate hypoechoic collection with septations (white arrowheads).
