Morel-lavellee lesion - an uncommon entity needs imaging consideration.
Pak J Radiol Jan ;28(1):50-3.

Morel-Lavallee lesions are relatively rare closed degloving injuries caused by a shearing force resulting in separation of the dermis and the hypodermis from the subjacent deeper fascia 1 . These shearing forces can disrupt perforating vessels and nerves, creating a potential space that fills with blood, lymph, debris, and fat (necrotic and/or viable) 2 . Although most commonly encountered lateral to the greater trochanter, these injuries may occur throughout the body in a variety of locations 1 . These lesions may not be well recognized at the initial presentation and can be easily missed. Patient`s history and imaging findings are very important in reaching the correct diagnosis. Radiological knowledge of this entity is pivotal in avoiding unnecessary patient`s worriment. We describe a case of 24 years old female who presented with a history of gradually increasing fluctuant swelling in the left gluteal region, and subsequently underwent imaging to reach the diagnosis of this lesion.
