Morel-Lavallée Lesion!
Soft tissue cystic lesion resulting from degloving at the junction between the subcutaneous tissues and underlying superficial muscle fascia. This traumatic “separation” of tissues creates a potential space.
The degloving injury is due to shear forces usually related to trauma and less likely liposuction procedure.
The degloving causes injury to small vessels and lymphatics, and thus composed of blood products, lymph, fat globules and debris.
Lesions are common about bony protuberance. This particular case is about the greater trochanter, which is the classic Morel-Lavallée lesion.
Due to blood products, the lesion usually shows high T1 and high T2 signal intensity without fat suppression on MRI. The enhancement is variable, but usually no central enhancement.
Acute cases are treated medically with compression. More chronic cases develop a fibrotic capsule and require surgical intervention and debridement.
Because injury to lymphatics and leakage, the lesion can continue to grow until definite treatment.
