Abstract
Objectives

We aim to review the characteristics of Morel-Lavallée lesions and to evaluate their treatment.

Material and methods

We retrospectively reviewed 17 patients (11 men and 6 women; mean age, 56.1 years, range 25–81 years) diagnosed with Morel-Lavallée lesions in two different departments. All patients underwent ultrasonography, 5 underwent computed tomography, and 9 underwent magnetic resonance imaging. Percutaneous treatment with fine-needle aspiration and/or drainage with a 6–8F catheter was performed in 13 patients. Two patients required percutaneous sclerosis with doxycycline.

Results

All patients responded adequately to percutaneous treatment, although it was necessary to repeat the procedure in 4 patients.

Conclusions

Radiologists need to be familiar with this lesion that can be treated percutaneously in the ultrasonography suite when it is not associated with other entities.

Keywords:
Magnetic resonance imaging

Resumen
Objetivo

Revisar las características de las lesiones de Morel-Lavallée y valorar su tratamiento.

Material y métodos

Hemos revisado de forma retrospectiva 17 pacientes diagnosticados de lesión de Morel-Lavallée en dos servicios diferentes: 11 hombres y 6 mujeres, edad media 56,1 años, rango de edad 25-81 años. En todos se hizo un estudio con ecografía, en cinco se realizó tomografía computarizada y en nueve resonancia magnética. Trece fueron tratados de forma percutánea mediante aspiración con aguja fina o drenaje con catéter de 6-8 F, o con ambos procedimientos. Dos pacientes requirieron esclerosis percutánea con doxiciclina.

Resultados

Todos los pacientes respondieron de forma adecuada al tratamiento percutáneo, aunque en cuatro hubo que repetir el procedimiento.

Conclusiones

El radiólogo debe estar familiarizado con esta patología cuyo tratamiento percutáneo, cuando no está asociada a otras afecciones, puede realizarse con éxito en la sala de ecografía.
