“…Mellado and Bencardino proposed a classification system which describes six types of MLLs classified based on shape, the presence of a capsule and other MR imaging characteristics. [16][17][18] Thus, MRI may potentially be used to establish if a capsule is present, and to stage or age lesions. 3,17,19 As MLLs are superficial, they also lend themselves to imaging by ultrasound, which can also allow for guidance for aspiration/drainage.…”

Introduction: Morel-Lavall ee lesions (MLL), also referred to as closed degloving injuries, result from traumatic shearing forces with separation of the subcutaneous fat from the underlying fascia. The aim of this study was to determine the incidence and treatment of MLLs at a level 1 trauma centre. Methods: Single-centre retrospective cross-sectional study of consecutive patients with an imaging diagnosis of a Morel-Lavallee lesion from 1/1/2010-31/12/2019. Demographic data, mechanism of injury, volume of lesion, management and outcome data were collated. Results: Sixty-six MLLs were identified in 63 patients (64% Male) with a median age of 49.5 years (19-94 years). Mechanism of injury were road traffic accidents in the majority (66%). Median injury severity score (ISS) was 17 (range 1-33). Patients on oral anti-coagulants had significantly larger lesions (181.9 cc v 445.5 cc, P = 0.044). The most common lesion location was the thigh (60.5%). Patients that underwent imaging within 72 h of injury had significantly larger lesions than those imaged more than 72 h after the inciting trauma (65 cc v 167 cc, P < 0.05). Management data were documented in 59% of lesions (39/66) in which 66.6% (n = 26) had invasive treatment. In the 31 patients where follow-up was available, 64.5% (n = 20) were persistent but decreasing in size. There was no significant difference in follow-up size for those who had invasive compared to conservative treatment (P = 0.3). Conclusion:The diagnosis of MLL should be considered for soft-tissue swelling in the context of shearing trauma. A variety of management options have been employed, with good overall outcomes.

“…Generally, a chronic lesion shows homogeneous hypointensity on T1-WI, hyperintensity on T2-WI, and a water-like MRI signal with a hypointense thick peripheral ring or capsule 2711). As the lesion evolves and matures, a peripheral ring or capsule develops and appears hypointense on T1-WI and T2-WI due to the presence of hemosiderin and fibrous tissue 715). In our case, MRI showed a fluid collection between the deep fascia and hypodermis, with homogeneous hypointensity on T1-WI, hyperintensity on T2-WI with internal septations, and a surrounding hypointense, thick peripheral capsule.…”

Morel-Lavallée Lesion in the Sacrococcygeal Area with Associated Coccygeal Fracture

A Morel-Lavallée lesion is a posttraumatic, closed internal degloving injury caused by shearing force abruptly separating the skin and superficial fascia from the deep fascia and creating a potential space. Blood, lymphatic fluid, and debris collect and fill the space. The most commonly affected sites are the thigh, knee, hip, and pelvic area, but the lesion can occur anywhere in the body. Among various treatments, surgical procedure is a good option if the lesion is chronic and a thick peripheral capsule has developed. We report an uncommon case of a chronic Morel-Lavallée lesion in the sacrococcygeal area, a rarely reported location, with an associated coccygeal fracture and dislocation.

“…Su aspecto anecoico se debe a que no contienen restos celulares o coágulos. No obstante, en sus fases iniciales, las lesiones de Morel-Lavallée (colección postraumática) se presentan con el aspecto ecográfico de los seromas, es decir, con contenido líquido anecoico; la clave diagnóstica para diferenciar estas últimas lesiones, es su típica localización en la zona peritrocantérica, con extensión variable al tercio proximal del muslo (27,28) ultrasonido hace posible observar su evolución de manera objetiva. La ecografia de alta resolución permite identificar con gran precisión los cuerpos extraños -incluso milimétricos-que no son evidentes mediante otros métodos diagnósticos (29,30) .…”

La Dermatología es una rama de la Medicina en la que se ha sentido ampliamente el impacto del desarrollo tecnológico del ultrasonido de alta resolución. En la actualidad, son múltiples sus indicaciones tanto en enfermedades benignas como malignas, y siguen creciendo día a día en beneficio de los pacientes.El ultrasonido no pretende reemplazar la juiciosa interpretación clínica del dermatólogo ni otras herramientas disponibles, como la dermatoscopia. Por el contrario, es una herramienta adicional que brinda información útil, invisible al ojo clínico, y que confirma, descarta o apoya el diagnóstico del médico tratante. El ultrasonido de alta resolución es preciso, accesible y de bajo costo, en comparación con otros métodos diagnósticos.En este artículo se revisan sus indicaciones, hallazgos y ventajas en algunas de las enfermedades dermatológicas benignas más frecuentes.
