Morel-Lavallée lesions are post-traumatic, closed degloving injuries occurring 
deep to subcutaneous plane due to disruption of capillaries resulting in an 
effusion containing hemolymph and necrotic fat. Magnetic resonance imaging (MRI) 
is the modality of choice in the evaluation of Morel-Lavallée lesion. Early 
diagnosis and management is essential as any delay in diagnosis or missed lesion 
will lead to the effusion becoming infected or leading to extensive skin 
necrosis.
