Morel-Lavallée lesion in lower back, an uncommon location: A case report with detailed literature review

Morel-Lavallée lesion is a post traumatic closed degloving injury. This occurs due to disruption of capillaries and lymphatics, resulting in a hemolymphatic collection between the subcutaneous fat plane and deep fascia. Early diagnosis and treatment are crucial to avoid complications such as encapsulation, infection, or skin necrosis. The thigh is the most common location for this lesion. We report a case of classical Morel-Lavallée lesion in posterior lumbar region, which is an uncommon location, diagnosed with imaging by Ultrasonography and computed tomography scan. We review the pathophysiology, clinical course, magnetic resonance imaging MRI features, and differential diagnosis of Morel-Lavallée lesions.
